Forward Acting Thrust
In How Airliners Fly it shows the workings of a jet engine and states:
"The fan, which is encased in a cowling, forces the compressed air backwards in the form of a jet, much in the form of a domestic electric fan. The engine itself experiences an equal and opposite force and this is the forward acting thrust which propels the aircraft".
If the thrust is coming out forward from the engine, how come the aircraft still flies forwards?

Newtons 3rd (I think) law of motion.
For every action there is an equal and opposite reaction.
Propel a mass of air rearwards and the resultant force (thrust) is forward.
Simples.

Although the action of producing thrust does produce a rearward force in the
engine!
engine!
The compressors and the diffuser section, amongst others, produce forward thrust. The turbine section produces a rearwards force.

Should have a Reply With Quote Button on here but anyway
So the total forward gas load less the rearward gas load produces total forward thrust?

thrust?
If you think it's wrong, then please feel free to put Rolls Royce on the right track!!!!
