Jet Engines
What are the 4 main sections of a jet engine?
What is Intake, Compression, Combustion, Exhaust
Newton’s ___ Law explains how thrust works.
Third
This engine is commonly found on airliners.
Turbofan
Which Aerospace Dimension is "Rockets"?
Aerospace Dimensions 4
Which engine is most common in Civil Air Patrol aircraft?
Propeller-Piston Engine
What part of the engine compresses incoming air?
What is the compressor
Name 2 forces that act on an airplane in flight.
Lift, Weight, Thrust, Drag
This engine is more efficient at supersonic speeds.
Turbojet
How many stages are needed for the model rocketry badge?
3
Which engine is better for high-speed, high-altitude flight?
Jet engine
What engine type has no bypass air?
What is the Turbojet
A balloon flying forward as air rushes out shows what law?
Newton’s 3rd Law
Which engine is noisier and used in older fighter aircraft?
Turbojet
What type of propulsion do most model rockets use?
Solid fuel rocket motors
Which engine type uses aviation gasoline (Avgas)?
Piston propeller engine
This part extracts energy from hot gases to spin the compressor.
What is the Turbine
What is the "action" when a rocket lifts off?
Exhaust gases are pushed downward
Which engine uses low pressure turbines to produce most of its thrust?
Turbofans
What is staging in rocketry?
Using multiple rocket motors in sequence for higher altitude
Why do jet engines perform better at higher altitudes than piston engines?
Higher Altitude results in thinner air and reduced drag
True or False: All the thrust in a turbofan comes from hot exhaust.
False — much comes from the fan bypass air
Explain how a propeller generates thrust.
It pulls/pushes air backward, creating forward motion
Which engine has a higher bypass ratio?
Turbofan
What organization’s safety code must be followed in CAP model rocketry?
National Association of Rocketry – NAR
Name two advantages of a propeller engine over a jet engine.
Cheaper Fuel, cheaper maintenance, simpler design, low speed efficiency
