Front 5

Main type of engine used today?

Back 5

Tubojet

Front 6

Mqin propulsion system in modern aircraft?

Back 6

Jet propulsion

Front 7

What produces thrust?

Back 7

Difference of speed between entering and exiting air

Front 8

Turbojet working principle

Back 8

1 air enters through inlet duct

2 compressor compresses air

3 compressed air has fuel added and is ignited in the combustion section

4 compressed air expands and it passes through turbine wheels which power the compressor

5 air exits engine at high velocities

Front 9

How much air does a jet engine intakes per second?

Back 9

1.2 tons
