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?:confused: |
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. :ok: |
If the thrust is coming out forward from the engine, how come the aircraft still flies forwards? |
By pushing all that air through the engine rearwards, the engine sucks it way forwards
|
I will do:ok:
Thanks all for your patience and replies, I get it now:ok: |
Although the action of producing thrust does produce a rearward force in the engine!
|
Isn't there a bloody big vacuum in front of the engine...?

Although the action of producing thrust does produce a rearward force in the 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:p
So the total forward gas load less the rearward gas load produces total forward thrust? |

Not so I'm afraid.

No I dont think you're wrong at all, am not qualified to think that:)
