  1. Lesson 7 – How are flying objects propelled? 6B: Tuesday April 17th 6A: Wednesday April 18th THRUST:Forward Motion

  2. Propulsion Lab!

  3. Squid & Octopus Propulsion!

  5. Jet Engine Propulsion! • _____ enters at the front of the engine and is compressed. • The air is mixed with _______ and the gases are ignited. • The gases _________ and rush out the jet’s tailpipe at very high speeds. • This force thrusts (propels) the plane __________. • http://www.youtube.com/watch?v=p1TqwAKwMuM&feature=related

  6. Airplanes vs. Rockets

  7. Rocket Propulsion! • Tremendous thrustis needed for space shuttles to lift off and escape the gravitational pull of earth. • Since there is no airin space, rockets must carry boosterscontaining oxygenas well as fuel. • The boosters drop off when their fuelis used up (2 minutes after being launched). • They land in the oceanand are retrieved by boat. • The external fuel tank is released 8 minutes into flight and burns up re-entering Earth’s atmosphere. • http://www.youtube.com/watch?v=vPQvTgD2quQ&feature=player_embedded
