What makes thrust? | AnswersDrive

Thrust is the force that propels a flying machine in the direction of motion. Engines produce thrust. Drag is the force that acts opposite to the direction of motion. Drag is caused by friction and differences in air pressure.

In this regard, what produces thrust?

The exhaust gases produced by a propeller, jet or rocket, due to Newton's Third Law, are feeling a force opposite and equal to the thrust, and therefore are moved in the direction opposite to the thrust of the engine. Hence, the exhaust is the effect of thrust.

How does a propeller generate thrust?

Like a wing, it produces lift, but in a forward direction—a force we refer to as thrust. Its rotary motion through the air creates a difference in air pressure between the front and back surfaces of its blades. In order for a propeller blade to spin, it usually needs the help of an engine.
