Tough question isn't it... the answer to this question is easy to understand but hard to accept. the answer lies in your ability to understand the evil of belief itself. Some watch a magic trick being performed and are completely amazed, other say.... "hey, wait a minute."

I understand that the previous answer is correct, but I will write it is scientifically. A common misconception is that thrust must push off another substance like air. This is in fact untrue because if you look at newtons third law you will see that (in its simplest form) that for every action there is an equal and opposite reaction. This means that the gases coming out of the jet is one force acting off of the jet itself therefore propelling it ;)

How is thrust used in jet engines?

Thrust is the main propulsion medium. The jet engines produce the thrust (the force forward) the air moves across the top of the wings creating a vacuum which in effect hold the aircraft in flight. The greater the engines are worked the greater the thrust and therefore speed.


How do jet engines provide a forward thrust to for an airplane?

The thrust is given by the difference in the velocity of air coming into the jet engine and going out of the jet engine, Thrust = F= mdV/dt = ma.


What is thrust in an aircraft?

Thrust is the power made by a jet engine to propel an aircraft.


What is the difference between a jet plane and a propeller?

A jet plane uses a jet engine's thrust for propulsion. A propeller is a set of blades somewhat like a big fan that blows air to the back of the plane for thrust instead of using a jet engine for the thrust to move the plane forward.


How does the after bunner jet engine work?

Jet fuel is sprayed into the exhaust gas steam and ignited, as this happens, the end of the primary nozzle constricts hydraulically and the result is increased thrust as the jet exhaust is "after burned".


How do jet planes fly?

Jet planes fly with the help of Thrust and Lift produced by the jet engines.


What is a thrust for the jet engines?

The forward propulsion of an aircraft is called thrust.The thrust is given by the engines.


What is the force that moves a plane forward?

Thrust. The pull of the propellers, the push of the jet engine, the pull of gravity.
