Propulsion Quiz

What is the primary purpose of propulsion in an aircraft?

• To generate lift

• To produce thrust to overcome drag

• To increase fuel efficiency

• To reduce the weight of the aircraft

What is the relationship between thrust and drag in straight and level flight?

• Thrust must be greater than drag

• Thrust must be less than drag

• Thrust and drag must be equal

• Thrust and drag are unrelated

In basic aerodynamics, propulsion is needed to:

• Maintain airflow over the wings to sustain lift

• Increase the angle of attack

• Decrease the aircraft’s weight

• Eliminate the effects of drag entirely

Which of the following principles explains the generation of thrust in aircraft propulsion?

• Bernoulli's Principle

• Newton’s Third Law of Motion

• Archimedes’ Principle

• Pascal’s Law

Which component of a turbojet engine is responsible for accelerating the exhaust gases to produce thrust?

• Compressor

• Turbine

• Combustor

• Nozzle

In a piston engine, thrust is generated by which process?

• Expanding gases pushing a turbine

• Moving pistons that turn a crankshaft to drive a propeller

• Injecting fuel into the engine

• Cooling engine parts
