Jet Engine Flashcards
(17 cards)
What is another name for a jet engine?
Turbojet engine.
How is a jet engine shut down?
By cutting off the fuel supply.
What are the four main types of jet engines?
Turbojet, turbofan, turboprop, and turboshaft.
Which jet engine type is the most basic and used in early jets/military aircraft?
Turbojet.
What is the key difference between a turbofan and a turbojet?
A turbofan adds a fan for extra thrust and efficiency, making it common in passenger planes.
Which jet engine type is used to power helicopter rotors?
Turboshaft.
Why are turboprops efficient for short-range flights?
They use a turbine to drive a propeller, which is efficient at slower speeds.
What is the function of the compressor in a jet engine?
To suck in and compress air.
What are the two types of compressors and where are they typically used?
Centrifugal flow compressor (military). Axial flow compressor (commercial airplanes).
What happens in the combustor (burner) section?
The compressed air mixes with fuel and burns continuously.
How can the combustor be turned off?
By cutting off the fuel supply.
What is the role of the turbine section?
It turns the compressor.
Which part of the jet engine produces thrust?
The nozzle.
How does thrust reversal help slow down an aircraft?
Clamshell doors deflect thrust forward, creating reverse thrust.
What is the purpose of an afterburner and where is it used?
It provides extra thrust for supersonic flight, takeoff, and combat (used in military aircraft).
How does an afterburner work?
By injecting additional fuel into the jet pipe downstream of the turbine.
What type of engine is jet engine?
Continuous Engine
