The forward force from a plane's engine is thrust.
A rocket in space operates off the expelled mass, from the conservation of momentum, dmv/dt = mdV/dt + Vdm/dt =0, The rocket is acceleration is mdV/dt = -Vdm/dt. The exhaust is Vdm/dt which is the force pushing the rocket forward as the exhaust goes out.
Rockets exert force at the upper part of the combustion chamber. This pushes the rocket forward.
The rocket is pushed forwards by the reaction to the force ejecting gas in the opposite direction to the direction of travel of the rocket. Rocket flight is an example of Newton's 3rd law of motion, which states that every action (force) has an equal and opposite reaction. In this case, the action is the ejection of rocket gas and the reaction is the forward force on the rocket.
The forward force from a plane's engine is called THRUST.

For every action (force) there is and equal and opposite reaction (force). When fuel is burned in a rocket or jet, the hot expanding gases leave the rear of the engine. The opposite is the force pushing the rocket itself forward.
Rockets have an exhaust of hot gas, moving rapidly away from the rocket, which is the action, and the reaction is that the rocket is propelled forward.
The Third Law of Motion, which states that for a given force, there is an equal reaction force. Burned fuel exits a rocket's backside, and the rocket moves forward.
