Transcript of IB Physics 11 Mr. Jean March 20 th, 2014. The plan: Video clip of the day Rocket Designs and builds.
Nose Cone Test:
• A proper nose cone must fit inside the rocket fuselage.– The fit should be snug– Nose cone should detach from body when an
individual quickly blows air through the body. • Do not have your parachute in when testing this!
Wing Test:
• In order to test the strength of the wings. A individual should be able to hold the entire rocket by one wing.– If the wing becomes unglued, falls off or
structurally fails this rocket is not suitable for flight.
Parachute Test:
• Take a 100g weight and attach parachute to it. Drop from ceiling with parachute fully open. The parachute should guide the weight softly to the ground without horizontal displacement. – Common Failures
• Parachute lines break• Parachute causes horizontal motion• Issues with parachute design
Engine Test Part #1:
• Engine should have a snug fit to the inside of the fuselage. – There MUST be a point where the engine can
not go past. • However there must remain hollow space to allow
the parachute deployment charge to function correctly.
– Engines are NOT to be glued into the rocket.
