Model Rocketry?
A hobby.
Which century did the Chinese turn black-powder–propelled objects into weapons?
13th
At what stage does the rocket come back down to Earth? (controlled descent)
Recovery
Method in which the rocket flutters down to Earth.
Featherweight Recovery
The launch site is next to a highway and is surrounded by trees, tension wires, and homes.
Fly in an open field.
Rocket?
A missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine.
Who described and sketched the important idea of multistage rockets?
Belgian Jean Beavie
What keeps a rocket stable?
Fins
Method in which the rocket tumbles back down to Earth.
Tumble Recovery
Material used to build the rocket includes heavy metal.
Don't use metal.
Propellant?
a substance that can propel something, in this case a rocket.
Who is considered to be the father of model rocketry?
George Harry Stine
What connects the nose cone, body tube, and parachute during recovery?
Shock Cord
Method in which the nose cone is ejected off using an ejection charge.
Nose-blow recovery
Recovery systems must be ______.
tested.
Aerodynamics
study of motion of air, particularly as an interaction with a solid object, such as an airplane wing or rocket fin.
Who invented model rocketry?
Orville Carlisle
What connects the rocket to the launch pad stand prior launch?
Launch Lugs
Method in which the ejection charge deploys an airfoil wing.
Glide Recovery
The weather today seems to be windy and rainy.
Don't fly in high winds or threatening weather
Rocket Engine?
uses stored rocket propellant as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas.
What Aerospace company was George Harry Stine fired from?
Martin
CHEMISTRY: In your rocket, the motor’s ejection charge will ignite and generate hot gases that pressurize the rocket’s airframe and exert a net force on the bulk-plate of the nose cone. This net force will eject the nose cone, shock cord, and parachute out of the rocket airframe. This all happens because the rocket is obeying the _____.
Ideal Gas Law.
Method in which the rocket is able to preform self-landing.
Vertical Takeoff and Vertical Landing
Brewing rocket fuel is dangerous.
Must be proven and tested.
