Pre Requrest Aerospace Propulsion 1AEPC304

What is the primary function of an aerospace propulsion system?

• To provide thrust to overcome drag
• To control the aircraft's direction
• To provide lift to the aircraft
• To control the aircraft's speed

Which of the following is NOT a type of aircraft propulsion system?

• Jet engine
• Rocket engine
• Propeller engine
• Hydraulic engine

In a turbofan engine, the bypass air is used for:

• Cooling the engine
• Increasing the thrust and to reduce the noise

• Reducing the noise
• Fueling the engine

Which law of motion is fundamental to understanding propulsion?

• Newton's First Law of Motion
• Newton's Second Law of Motion
• Newton's Third Law of Motion
• Law of Universal Gravitation

The process of compressing incoming air in a jet engine is typically achieved by a:

• Piston
• Turbine
• Compressor
• Exhaust nozzle

Which type of propulsion system is most commonly used in rockets for space exploration?

• Jet propulsion
• Diesel engine
• Electric motor
• Liquid propellant rocket

The Mach number is a measure of an aircraft's:

• Speed relative to the speed of sound
• Fuel efficiency
• Altitude
• Weight

Which of the following is an advantage of a scramjet engine?

• It can operate at hypersonic speeds
• It requires less fuel than a jet engine
• It is quieter than a jet engine
• It is easier to maintain than a jet engine

The specific impulse of a propulsion system is a measure of its:

• Thrust-to-weight ratio

  
  

• Stability in flight

  
  

• Fuel Efficiency

• Noise level
