A History of Aviation Notes
What is “Aviation?” • Aviation is… • a field of study which includes not only flying, but all activities relating to airborne devices created by humans, generally known as aircraft. • the design, development, production, operation and use of aircraft.
Early Efforts of Flight • Around 400 BCE – China • The discovery of the kite that could fly in the air got humans thinking about flight. • Kites were first used by the Chinese in religious ceremonies. • Were later used to test weather conditions and in warfare as a way to scare enemies. • Were the forerunner to balloons and gliders.
Early Efforts of Flight • Hero and the Aeolipile • The ancient Greek engineer Hero of Alexandria worked with steam and air pressure to create sources of power. • One experiment that he developed was the aeolipile. • Hero mounted a sphere on top of a water kettle. • A fire below turned the water to steam, which traveled up pipes to the sphere. • Two L-shaped tubes on opposite sides of the sphere allowed the steam to escape, which gave a thrust to the sphere that caused it to rotate.
Early Efforts of Flight • Leonardo da Vinci • Sketched the first ornithopterin 1488. • The first ornithopters capable of flight were built in France in 1858 – almost 400 years later.
Lighter than Air Aircraft • The Hot Air Balloon • Designed by the Montgoflier brothers in 1783. • A duck, sheep and rooster first flew on June 5. • Had its first successful manned flight onNovember 21. • Could not be steered and could onlyfly downwind. • The first steerable hot air balloonwasn’t built until 1901 – over 100years later.
Homework… • Read “The Invention of Lighter-than-air Craft” • Create a Bubble Map describing the facts surrounding the invention of the first hot air balloon and/or the use of balloons from their invention up to today.
The Hot Air Balloon (continued) • In 1794, the French used a tethered balloon to observe the battlefield and direct attacks during the French Revolution. • In 1837, Canadian John Ray successfully launched a weight-carrying balloon.
Heavier than Air Aircraft • George Cayley (1799-1850’s) designed the first gliders that used movements of the body to control. • A 10 year old boy was the first to fly one of his gliders. • For 50 years, he made improvements to his gliders. • He changed the shape of the wings so that air could flow over the wings correctly. • He designed a tail for the gliders to help with the stability. • Is considered to be the “Father of Modern Aviation.”
Heavier than Air Aircraft • Otto Lilienthal • German engineer who studied aerodynamics, is the first person to make repeated successful gliding flights – over 2,500 flights. • In 1891, he built the first glider for long distance flights. • Wrote a book on aerodynamics that was used by the Wright Brothers as the basis for their designs.
Heavier than Air Aircraft • Samuel P. Langley • In 1891, Samuel Langley realized power was needed to help man fly for long periods of time. • His model called the Aerodrome was steam-powered and flew 3/4s of a mile before running out of fuel. • Attempted to make the first piloted heavier-than-air aircraft. His models flew, but his first two attempts at piloted flight were not successful.
Homework… • Read “The Wright Flights” and “Wright Brothers’ Plane: How Did It Fly?” • Create a Bubble Map describing the facts surrounding the Wright Brothers and the events leading up to and following their famous first flight.
Classwork… • Create a Double Bubble Map comparing and contrasting the Montgolfier Brothers and the Wright Brothers and their inventions. • This will serve as a template for two8-sentence paragraphs you will write comparing and contrasting the Montgolfier and Wright Brothers. • Please turn in (all stapled together): • Balloon (Montgolfier Brothers) Bubble Map • Airplane (Wright Brothers) Bubble Map • Double Bubble Map • 2 Paragraphs
