The ancient Greeks and Romans pictured many of their gods with winged feet, and imagined mythological winged animals. According to the legend of Daedalus and Icarus, the father and son escaped prison by attaching wings made of wax and feathers to their bodies. Unfortunately, Icarus flew too near the sun, and the heat caused the wax and feathers to melt. The feathers fell off, and Icarus plummeted to the sea. Daedalus landed safely in Sicily. Hero’s Engine About 100 BC, a Greek inventor known as Hero of Alexandria came up with a new invention that depended on the mechanical interaction of heat and water. He invented a rocket-like device called an aeolipile. It used steam for propulsion. Hero mounted a sphere on top of a water kettle. A fire below the kettle turned the water into steam, and the gas traveled through the pipes to the sphere. Two L-shaped tubes on opposite sides of the sphere allowed the gas to escape, giving a thrust to the sphere, causing it to rotate. http://history.msfc.nasa.gov/rocketry/02.html http://www.grc.nasa.gov/WWW/K-12/TRC/Rockets/IMAGES/History1.gif

At some point, they attached bamboo tubes to arrows and launched them with bows. Soon they discovered that these gunpowder tubes could launch themselves just by the power produced from the escaping gas. The true rocket was born. The “Fire Arrow” sounded more like fireworks but the Chinese used the rockets as weapons in battle. Chinese Repulse Mongols In 1232 AD, the Chinese used rockets against the Mongols who were besieging the city of Kai-fung-fu. An arrow with a tube of gunpowder produced an arrow of flying fire.

Forty seven assistants, each armed with torches, rushed forward to light the fuses. There was a tremendous roar accompanied by billowing clouds of smoke. When the smoke cleared, the flying chair and Wan-Hu were gone.

Enemy troops in India repulsed the British with rockets. Later in Britain, Sir William Congreve developed a rocket that could fire to about 9,000 feet. The British fired Congreve rockets against the United States in the War of 1812. Indian Troops Rout British The English confrontation with Indian rockets came in 1780 at the Battle of Guntur. The closely massed, normally unflinching, British troops broke and ran when the Indian Army laid down a rocket barrage in their midst.

The British used Congreve rockets in 1806 to attack Napoleon's headquarters in France. In 1807, Congreve directed a rocket attack against Copenhagen; approximately 25,000 rockets were fired. Credit: TRW Inc. and Western Reserve Historical Society, Cleveland, Ohio The Rockets’ Red Glare Francis Scott Key coined the phrase the "rocket's red glare" after the British fired Congreve rockets against the United States in the War of 1812. Congreve had used a 16-foot guide stick to help stabilize his rocket. William Hale, another British inventor, invented the stickless rocket in 1846. The U.S. army used the Hale rocket more than 100 years ago in the war with Mexico. Rockets were also used to a limited extent in the Civil War.

7. http://history.msfc.nasa.gov/rocketry/14.html Rockets as Inventions - Late 19th Century Small Animals Launched During the 19th century, rocket enthusiasts and inventors began to appear in almost every country. Some people thought these early rocket pioneers were geniuses, and others thought they were crazy. Claude Ruggieri, an Italian living in Paris, apparently rocketed small animals into the sky as early as 1806. The payloads were recovered by parachute. As depicted here by artist Larry Toschik, French authorities were not always impressed with rocket research. They halted Ruggieri's plans to launch a small boy using a rocket cluster.

Skillful theorists, like Russian Konstantian Tsiolkovsky (1857-1935), were examining the fundamental scientific theories behind rocketry. They were beginning to consider the possibility of space travel. In 1892, he began publishing science fiction stories including his speculations on spaceflight. In 1895, he published “Dreams of the Earth and Sky” envisioning artificial satellites, space stations and colonies, artificial gravity, interstellar travel and the possibility of extraterrestrial life. Rocket Designs by Tsiolkovsky In 1898 Tsiolkovsky,a schoolteacher, proposed the idea of space exploration by rocket. In a report he published in 1903, Tsiolkovsky suggested the use of liquid propellants for rockets in order to achieve greater range. Tsiolkovsky also stated that the speed and range of a rocket were limited only by the exhaust velocity of escaping gases. For his ideas, careful research, and great vision, Tsiolkovsky has been called the father of modern astronautics. http://www.grc.nasa.gov/WWW/K-12/TRC/Rockets/history_of_rockets.html http://history.msfc.nasa.gov/rocketry/19.html Rockets into Space by Craig Frank H.

He was a theoretical scientist as well as a practical engineer. His dream was the conquest of the upper atmosphere and ultimately space through the use of rocket propulsion. In the 1950's, American rocket scientists discovered that it was virtually impossible to construct a rocket or launch a satellite without acknowledging the work of Dr. Goddard. More than 200 patents, many of which were issued after his death, covered this great legacy. First Flight of Liquid Propellant Rocket Dr. Goddard is shown with the first liquid propellant rocket in the frame it was launched from on March 16, 1926, at Auburn, MA. Fueled by liquid oxygen and gasoline, the rocket flew for only 2.5 seconds, climbed 41 ft, and landed 184 ft away.From 1930 to 1941, Dr. Goddard made substantial progress in the development of progressively larger rockets that attained altitudes of 7,874 ft. He refined his equipment for guidance and control, his techniques of welding, and his insulation, pumps and other associated equipment. In many respects, he laid the essential foundations of practical rocket technology. He is considered one of the fathers of rocketry along with Konstantin Tsiolovsky and Hermann Oberth. http://grin.hq.nasa.gov/ABSTRACTS/GPN-2002-000132.html

Rocket with turbo-pumps that inject propellants into the combustion chamber is shown on its assembly frame without its casing at the Goddard workshop in Roswell, New Mexico in 1940. In 1930, he shifted his entire rocket operation to Roswell to escape publicity. The new location also provided wide-open spaces and excellent climate for testing. http://dayton.hq.nasa.gov/IMAGES/LARGE/GPN-2002-000140.jpg

A Hungarian-born German, he is considered to be one of the top three pioneers in modern rocketry - Konstantin Tsiolkovsky and Robert Goddard are the other two. Oberth was the only one out of the three to see human spaceflight come to fruition. Oberth was a guest at the Apollo 11 moon landing launch on July 1969 as well as at the launch of the STS-51J, Space Shuttle Atlantis mission.He is credited with suggesting that space stations would be essential if humans wished to travel to other planets. He was inspired by the tales of Jules Verne in From the Earth to the Moon and Travel to the Moon. Oberth’s Liquid Fueled Rocket Team In 1923, Oberth (right of his rocket) published a book about rocket travel into outer space. Because of his important writings, many small rocket societies sprang up around the world. In the spring of 1930, an eighteen year old Wernher von Braun (second from the right) assisted Oberth in his early experiments in testing a liquid fueled rocket with a thrust of about 15 pounds. After the three pioneers, rocketry required large teams of experts; a small team could not keep pace with the advancing technologies. http://www.allstar.fiu.edu/aero/rock2.htm http://history.msfc.nasa.gov/rocketry/28.html http://grin.hq.nasa.gov/ABSTRACTS/GPN-2003-00099.html

12. http://history.msfc.nasa.gov/rocketry/29.html 20th Century Rockets - Early to Mid-20th Century V-2 Rocket The Germans, under the technical direction of Wernher von Braun, developed the V-2 at their Peenemuende Research Facility in Germany. The V-2 became one of the best known of all early missiles. The 46.9 ft rocket used alcohol and liquid oxygen as propellant and could carry a 1,650 pound warhead 225 miles. It had a takeoff weight of 28,229 lbs and a thrust of 59,500 lbs for 68 seconds. Some historians have estimated that by the end of World War II, the Germans had fired nearly 3,000 V-2 weapons against England and other targets. First Launch into Space On October 3, 1942, the V-2 was the first rocket to be launched into space. It attained a 125 mile range and came within 2.5 miles of its target, reaching a top speed of 3,300 miles per hour and a peak altitude of 60 miles, or the fringes of space. The first two launches, on June 13 and August 16, 1942, were failures. The photograph to the right measures 8 x 10 inches and includes the signatures of Wernher von Braun, and Konrad Dannenberg and Raketen Gruppe, members of Von Braun's team.

14. http://history.msfc.nasa.gov/rocketry/30.html 20th Century Rockets - Early to Mid 20th Century Von Braun Team Moved to the U.S. As the war ended, the United States developed an interest in the technical capability of the Germans. A team of American scientists was dispatched to Europe to collect information and equipment related to German rocket progress. "Project Paperclip" enabled the German rocket specialists to come to the United States to advance American rocketry. V-2 at White Sands The German team of specialists was initially assigned to Fort Bliss, TX where they reassembled and tested V-2 rockets brought to America from Germany. Later, they were re-assigned to Redstone Arsenal in Huntsville, Alabama. In Huntsville, the German team, as well as an increasing number of American-born members, would develop plans for exploring space and would build the rockets that would serve as the foundation for the American space program for years to come. http://history.msfc.nasa.gov/rocketry/31.html http://grin.hq.nasa.gov/ABSTRACTS/GPN-2003-00099.html

15. http://en.wikipedia.org/wiki/Rocket Space Race Rockets - Mid 20th to Late 20th Century Soviets Launch First Satellite and First Human into Space Independently, research continued in the Soviet Union under the leadership of the chief designer, Sergei Korolev. With the help of German technicians, the V-2 was duplicated and improved as the R-1, R-2 and R-5 missiles. German designs were abandoned in the late 1940s, and the German workers were sent home. A new series of engines using liquid oxygen and kerosene as propellant were built by Valentin Glushko and based on inventions of Aleksei Mihailovich Isaev. This formed the basis for the first intercontinental ballistic missile (ICBM), the R-7. Korolev was aware that a ICBM also had the capability to launch satellites and humans into orbit around the Earth. The R-7 launched Sputnik and then Yuri Gagarin into Earth orbit. It was the biggest leap in rocketry since the German V-2. Derivatives of the R-7 are still in use today. The R-7 that launched the Sputnik-2 spacecraft carrying the dog, Laika, the first living creature to orbit Earth on November 3, 1957, is shown. http://grin.hq.nasa.gov/IMAGES/LARGE/GPN-2002-000182.jpg http://en.wikipedia.org/wiki/Rocket http://grin.hq.nasa.gov/ABSTRACTS/GPN-2003-00099.html

The Von Braun team was ready when the United States turned to the Huntsville group to launch America's first satellite.On January 31, 1958, a modified Army Redstone rocket lifted the first American satellite into orbit just 3 months after the Von Braun team received the go-ahead. This modified Redstone rocket was known as Jupiter-C. Its satellite payload was Explorer I. Explorer I Architects The three men responsible for the success of Explorer 1 are (from left to right): Dr. William H. Pickering, former director of JPL that built and operated the satellite; Dr. James A. van Allen, from the University of Iowa who designed and built the instrument on Explorer I that discovered the radiation belts circling the Earth; Dr. Wernher von Braun, leader of the Army's Redstone Arsenal team that built the first stage Redstone rocket that launched Explorer 1. http://grin.hq.nasa.gov/ABSTRACTS/GPN-2000-000478.html http://grin.hq.nasa.gov/IMAGES/LARGE/GPN-2000-000478.jpg http://grin.hq.nasa.gov/ABSTRACTS/GPN-2003-00099.html

Its development goes back to just after World War II when captured German rocket and missile technology supported many new missile research studies. In 1953, Convair completed the initial design studies. Innovations introduced in the development of the Atlas included: movable thrust chambers mounted on gimbals to provide directional control, integral airframe and tank structure to reduce deadweight and thus increase range and payload, the use of vernier engines to obtain precise velocity and attitude adjustments, and a separable warhead re-entry vehicle. The fuel tank containing a kerosene mixture and the oxidizer tank with liquid oxygen was separated by an intermediate bulkhead. If the tanks were not pressurized, the entire structure collapsed. The first silo-stored Atlas F squadron became operational in November 1962. The Atlas was 75 ft long and its 10 ft diameter flared to 16 ft at the nacelles. An Atlas D missile was adapted to carry the manned Mercury capsule. Astronaut John Glenn became the first American to orbit the Earth on February 20, 1962 aboard Friendship 7 launched by the Mercury - Atlas rocket at Cape Canaveral, FL.

Two Apollo 11 crewmen were the first to land on the moon. The Saturn V rocket was the largest rocket ever used by NASA and the only one able to lift the large masses needed to land astronauts on the moon and return them safely. Saturn V rockets launched all of the Apollo moon missions and several to Earth orbit. The rocket could place a 285,000 lb payload into Earth orbit or send 100,000 lbs to the moon. The three-stage, 363 ft tall Saturn V was the culmination of years of development. The “V” stood for the five first stage F-1 rocket engines delivering a total of 7.65 million lbs at sea level. The oxidizer was liquid oxygen and the fuel was RP-1 (kerosene). The second stage was powered by five J-2 engines generating a total thrust of 1.0 million lbs. The third stage was a single J-2 engine yielding 200,000 lbs of thrust (later up-graded to 230,000 lbs). The J-2 engines used liquid oxygen and liquid hydrogen as the oxidizer and fuel, respectively.

Valier insisted that re-useable spacecrafts were superior to expendable rockets. Eugen Sanger, an Austrian aeronautical engineer, believed that such a space plane could be used for the construction, transport, and supply of a space station. The space shuttle orbiters were the first spacecraft capable of routinely launching into orbit like rockets and then returning to Earth as gliders. The orbiters were part of the Space Transportation System used for scientific research and space applications. The first space shuttle, the orbiter named Colombia, was launched April 12, 1981 at the Kennedy Space Center, FL. The Earth orbital mission lasted 54 hours and ended with an un-powered landing at Edwards Air Force Base, CA. The space shuttle was retired in July 2011 after flying 135 missions.

The line then branched into three parallel paths, one to each engine. Liquid hydrogen (LH2) fuel, at -423 OF, from the External Tank flowed into the orbiter at the liquid LH2 feed line disconnect valve. It then entered the orbiter LH2 feed line manifold and branched out into three parallel paths to each engine. http://history.nasa.gov/ap11-35ann/kippsphotos/apollo.html

They were the largest solid-propellant motors ever flown and the first designed for reuse. Prior to launch, the SRBs carried the entire weight of the external tank and orbiter through their structure to the mobile launcher platform. Seventy-five seconds after SRB separation, SRB apogee occurred at an altitude of 41 miles; parachutes were deployed and impact occurred in the ocean approximately 141 miles downrange. The SRBs were recovered and processed to be used again. Each booster had a thrust of approximately 3,300,000 lbs at launch providing 71.4 % of the thrust at lift-off. The SRBs were ignited after the three Space Shuttle Main Engines' thrust level was verified. Each was 149.16 ft long and 12.17 ft in diameter and was comprised of four segments. The propellant mixture in each SRB motor consisted of an ammonium perchlorate (oxidizer, 69.6% by weight), aluminum (fuel, 16%), iron oxide (catalyst, 0.4%), a polymer (binder that holds the mixture together, 12.04%), and an epoxy curing agent (1.96%). The cone-shaped aft skirt reacted the loads between the SRB and the mobile launcher platform. Four separation motors mounted on the skirt released the shuttle from the mobile launch platform. The nozzle was a convergent-divergent design using a gimbal mechanism to help steer the shuttle. The Space Shuttle Operator’s Manual, Kerry Mark Joels, Random House, 1982

It had the capacity to place up to 110 tons in low Earth orbit. It could be configured for heavier payloads comparable to, or even greater than, the Saturn V. On May 15, 1987, it initially launched Polyus (shown to the left atop the rocket), a military test-bed put together on a crash basis as an answer to America's Star Wars program. Polyus failed to reach orbit, but if it had succeeded, it would have been the core module of a new Mir-2 space station. Its mere presence could have decisively changed the shape of the Cold War in its final months. Soviet Shuttle Launched On November 15, 1988, Energia launched an unmanned Buran re-usable shuttle. After two orbits, Buran landed at an airfield. The Soviet re-usable spacecraft program Buran (snowstorm or blizzard) began in 1976 as a response to the NASA Space Shuttle. The objectives were similar to those of the U.S. program except Buran would re-supply the Mir space station. Buran did not fly a manned mission. Production of Energia rockets ended with the fall of the Soviet Union and the end of the Buran shuttle project. Rockets into Space by Craig Frank H.

The Orion Multi-Purpose Crew Vehicle (MPCV) will serve as the primary crew vehicle for missions beyond low Earth orbit (LEO). The MPCV will be capable of conducting regular in-space operations such as rendezvous, docking and extravehicular activity, in conjunction with payloads delivered by the Space Launch System (SLS) or other vehicles in preparation for missions beyond LEO. NASA has selected a 27.5 ft diameter space shuttle-derived vehicle with two existing stages and two strap-on boosters for the initial lift version shown to the left launching the Orion MPVC.The SLS will be able to initially lift 154,000 - 220,000 lbs (70 - 100 metric-tons) to LEO, and evolvable to 286,000 lbs (130 metric-tons) or more. Orion Asteroid Mission This artist's rendering represents a concept of the Orion spacecraft with an astronaut investigating a near Earth asteroid (NEA). Asteroids have gained significant attention recently especially with President Obama’s announcement in April 2010 that a human mission to an asteroid no later than 2025 would be one of NASA’s new exploration goals. Near Earth Asteroids (NEA) come close enough to Earth that the proximity of some NEAs makes them ideal destinations for human exploration missions. http://www.lockheedmartin.com/data/assets/ssc/Orion/Toolkit/AsteroidCovhi.jpg Stepping Stones: Exploring a Series of Increasingly Challenging Destinations on the Way to Mars; Lockheed Martin, Denver, CO - Orion missions are discussed

24. Future Rockets - Human Space Exploration Program Cargo Configuration The 320 ft tall initial lift SLS (70 - 100 metric-tons) will use a liquid hydrogen and liquid oxygen propulsion system equipped with three RS-25D/E shuttle main engines. The evolved lift capability (130 metric ton) SLS is an upgraded version with five RS-25D/E engines that will have a liftoff thrust of 9 million pounds and be able to launch more than 286,000 lbs of cargo into low Earth orbit. Keeping the 27.5 ft core booster's diameter the same as the shuttle's external tank permits the use of existing ground equipment and sharing components between the first and second stages. The Mobile Launch Platform hardware developed for the Ares program will then be able to be used for the SLS. The upper stage will be powered by the J-2X engine developed by Pratt & Whitney Rocketdyne. The J2X is based on the upper stage engine for the Saturn V moon rocket. The twin boosters would either be propelled by solid-fuel or liquid-fuel. A competition will determine the solid-fuel or liquid-fuel booster needed to allow the vehicle to evolve to the 130 metric-ton capability that Congress ordered in the 2010 NASA reauthorization legislation. Development of a kerosene-fueled engine will be considered. 400 ft Cargo Fairing Upper Stage with J-2X Engine Core Stage Solid or Liquid Rocket Booster (2 Places) RS-25D/E Engine (5 Places) Credit: NASA http://www.nasa.gov/pdf/588413main_SLS_Fun_Facts.pdf http://www.nasa.gov/exploration/systems/sls/sls1.html http://spaceflightnow.com/news/n1109/14heavylift/ http://www.aviationweek.com/aw/generic/story.jsp?id=news/awx/2011/06/16/awx_06_16_2011_p0-337088.xml&channel=space

Chemical rockets create their exhaust by the combustion of rocket propellant. The action of the exhaust against the inside of combustion chambers and expansion nozzles accelerates the gas to extremely high speed and exerts a large reactive thrust on the rocket. Today's rockets are remarkable collections of human ingenuity that have their roots in the science and technology of the past. They are natural outgrowths of literally thousands of years of experimentation and research on rockets and rocket propulsion. How it Works A balloon provides a simple example of how a rocket engine works. After the balloon is blown-up and tied, the balloon is in equilibrium; it does not move by itself. When the balloon is untied, the air trapped inside the balloon pushes out the open end, causing the balloon to move forward. The force of the air escaping is the "action;” the movement of the balloon forward is the "reaction" predicted by Sir Isaac Newton's Third Law of Motion stating that for every action (force) in nature there is an equal and opposite reaction.

30. Rockets as Inventions - Late 19th Century Tsiolkovsky’sRocket Concepts • The big breakthrough in rocket technology was the use of liquid propellants that Konstantin Tsiolkovsky advocated at the turn of the 19th Century. The liquids are stored in separate tanks and fed into the combustion chamber either under the pressure of a stored gas or by means of pumps. The thrust can be controlled by valves. Later, the rocket pioneers quickly discovered that combustion chambers and nozzles can burn through if they are not properly designed. Some of the first motors were provided with water-cooling jackets. Soon, regenerative cooling was introduced that used part of the fuel, after circulating in the jacket, and then entered the chamber for combustion with the oxidant. • Concept 1 - The first spaceship design in 1903 envisioned the use of liquid hydrogen (LH2) and liquid oxygen (LO2). It incorporated a pressure cabin and exhaust vanes for thrust vector control (TVC). • Concept 2 - The 1914 design was a development of the 1903 design in which the passenger lay supine. It featured double-walled construction, including the pressure cabin and TVC, and was remarkable in that combustion took place in an offset chamber that exhausted into a curved tube that would have greatly impaired performance. • Concept 3 - The 1915 design is taken from the jacket of the book Lunar Travel On the Moon (Moscow, 1935). Internal detail now shows inlet valves for LO2 and LH2. 1 2 3 Legend: Oxidant Combustion Fuel http://history.msfc.nasa.gov/rocketry/19.html

An alcohol burner between the tanks was used to increase vaporizing of the liquid oxygen. A starting hose (pulled free as the rocket began to rise) fed oxygen from a ground supply cylinder through the oxygen gas pressure line. Cork float valves prevented the liquid propellants from spilling into the pipes while still allowing the gas to flow. The supply of fuel/oxidant to the igniter that contained match heads and black gunpowder provided the initial explosion. De Laval Nozzle De Laval Nozzle Throat Low Pressure High Velocity Gas High Pressure Low Velocity Gas Supersonic Subsonic Convergent Section Divergent Section In 1915, Robert Goddard found that rockets of the time were not very efficient. Only 2% of the energy released was used to accelerate the exhaust. Since a faster exhaust means more power, he looked for effective ways to channel the exhaust. Gustav De Laval, a Swedish engineer, had invented a nozzle while working on steam engines. De Laval found that the most effective way to generate a high speed jet was with a nozzle that alternately converged and diverged. http://www2.jpl.nasa.gov/basics/bsf3-2.php

Sutton, American Institute of Aeronautics and Astronautics, Inc., Reston, VA, 2006 20th Century Rockets - Early to Mid 20th Century Third Stage Second Stage Legend: Oxidant First Stage Combustion Fuel Legend: Oxidant Fuel Combustion Pressurant Oberth’s Cone Motor Oberth’s Modell B Rocket Oberth's “Kegelduese,” cone motor, of 1929 set the pattern for the VfR's (the German Society for Space Travel) early rocket engine experiments. The liquid oxygen/gasoline motor was comprised of two halves secured by bolts. It was made of steel and heavily copper plated on the inside. The lower half included the nozzle. In 1930, the cone motor performed for 90 seconds delivering a constant thrust. Oberth's three stage rocket concept is a design for a sounding rocket. Although the rocket was never built, it is considered the predecessor of the modern multi-stage rocket incorporating stabilizing fins. In the first stage, fueled by alcohol/water and liquid oxygen, the alcohol/water also functioned as a cooling agent around the thrust chamber and nozzle throat. The second and third stage propellants were liquid oxygen and liquid hydrogen. The third stage was needed to propel it to an altitude of 18,000 ft where it would separate.

The rocket reached a height of 50 miles before the engine shutdown. • The fuel and oxidizer turbo-pumps were steam turbines, and the steam was produced by concentrated hydrogen peroxide with a potassium permanganate catalyst. The alcohol-water fuel was pumped along the double wall of the main combustion burner. This cooled the chamber and heated the fuel. The fuel was then pumped into the main burner chamber through 1,224 nozzles, assuring the correct mixture of alcohol and oxygen. Small holes also permitted some alcohol to escape directly into the combustion chamber, forming a cooled boundary layer that further protected the wall of the chamber, especially at the throat where the chamber was narrowest. The boundary layer alcohol ignited in contact with the atmosphere, accounting for the long, diffuse exhaust plume. • The V-2 was guided by four external rudders on the tail fins and four internal graphite vanes at the exit of the motor. The guidance system consisted of two free gyroscopes (a horizon and a vertical) for lateral stabilization, and a gyroscopic accelerometer connected to an electrolytic integrator (engine cut-off occurred when a thin coating of silver was electrochemically eroded off a poorly conducting base). Some later V-2s used "guide beams" (radio signals transmitted from the ground) to navigate towards the target, but the first models used a simple analog computer that adjusted the azimuth for the rocket, and the flying distance was controlled by the timing of the engine cut-off, ground controlled by a Doppler system or by different types of on-board integrating accelerometers. The rocket stopped accelerating and soon reached the top of the (approximately parabolic) flight curve. http://grin.hq.nasa.gov/ABSTRACTS/GPN-2003-00099.html

Sergei Korolev's solution was a "cluster of clusters." The R-7s central or "sustainer" engine was a single RD-108. Surrounding the rocket were four RD-107s serving as boosters that were jettisoned after use. Igniting the sustainer and booster engines on the launch pad resolved the concern whether stage engines could be ignited in the space environment. Heating and burning stability problems were resolved by using a single turbo-pump to feed four thrust chambers leading to the four-chambered RD-I07 and RD-I08 engines. As a result, the R-7’s total of 32 large and small vernier combustion chambers collectively produced more than 1.1 million pounds of thrust at lift-off. To save weight and to streamline the rocket, the boosters were placed in tapered pods with a fin protruding from each. The overall diameter for the Sputnik version of the R-7 was 33.7 ft, the length was 95.7 ft, and the estimated loaded weight was 588,735 lbs. Rockets into Space by Craig Frank H.

35. Space Race Rockets - Mid 20th to Late 20th Century Atlas Propulsion System Each rocket engine consisted of the thrust chamber (except for the booster engine, which had two), the pump and valves that controlled the flow of propellants to the thrust chamber. The engines started on propellants from the fuel and oxidizer main tanks. The thrust chambers were cooled by flowing fuel through tubes in the thrust chamber walls, and gimbaled to allow movement in any direction. Pyrotechnic devices ignited the propellants as they flowed into the thrust chambers. Propellants from the engine tanks also entered and ignited in gas generators. The hot gases of combustion drove turbo-pumps that forced propellants from the tanks into the thrust chambers and gas generators until the engines were shut down. The rocket engines started and developed thrust before the missile was released from the launch pad. When the vehicle was released, the thrust of the engines lifted the missile from the pad and accelerated it. At staging, the booster engines were cut off and the booster sections separated. The missile continued to accelerate, propelled by the sustainer and vernier engines. The sustainer engine was cut off and; after attitude and direction were corrected, the two vernier engines were cut off.

Space Race Rockets - Mid 20th to Late 20th Century Forward Skirt Oxidizer (LO2) Tank Intertank Section Fuel (RP-1) Tank Thrust Structure F-1 Engine (5 Places) Engine Fairing & Fin Heat Shield Saturn V S-1C Stage The S-IC provided the first stage boost of the Saturn V launch vehicle to an altitude of about 38 miles and acceleration to increase the vehicle velocity to 7,700 feet per second. It then separated from the S-II stage and fell to Earth about 360 miles downrange. The S-IC stage was a cylindrical booster, 138 feet long and 33 feet in diameter, powered by five liquid propellant F-l rocket engines. The stage dry weight was approximately 293,500 pounds and its total weight at ground ignition was approximately 5,030,500 pounds. The primary structural material was aluminum alloy. The major components were the: forward skirt, oxidizer tank, intertank section, fuel tank, and thrust structure. Four hold-down points in the lower ring of the thrust structure supported the fully loaded Saturn/Apollo (over 6,000,000 pounds) and also restrained the vehicle from lifting off at full F-I engine thrust. The heat shield provided thermal shielding for critical engine and structural components during the flight. Each outboard F-l engine was protected from aerodynamic loading by a conically shaped engine fairing. The fairings also enclosed the engine actuator supports. Four fixed, titanium covered, stabilizing fins augmented the stability of the Saturn V vehicle. Saturn V Flight Manual, MSFC-MAN-506, NASA/Marshall Space Flight Center, 1969

They were throttled during ascent and they moved, “gimbaled,” to help steer the shuttle. The SSME burned liquid hydrogen (LH2) and liquid oxygen (LO2) to produce a rated thrust of 400,000 lbs at sea level. Each SSME was designed to operate for a total of up to 71/2 hours between major overhauls. At a rate of only 8 minutes per flight, the engines should have lasted for fifty-five missions. The SSME used a two-stage combustion process. LO2 and LH2 were pumped from the External Tank and burned in two preburners. On the way to the preburner, some super-cold LH2 was diverted from the mainstream and circulated through tubes in the engine's nozzle and combustion chamber walls cooling the engine. Eventually, all the H2 found its way to the preburner. The mixture ratio of O2 to H2 was less than one part O2 to one part H2. A very hot H2-rich steam resulted from this mixture. The hot gas drove the high-pressure propellant turbopumps before it was ducted into the main injector, where it mixed with the rest of the O2 and was fed to the combustion chamber where the second stage of combustion occurred. The expansion of the gases through the chamber and the nozzle produced thrust. In about 8 minutes, 40 seconds, the three SSMEs burned over 1.6 million lbs of propellant (approximately 528,000 gallons). http://en.wikipedia.org/wiki/Space_Shuttle_main_engine
