In aircraft, thrust is generated by the reaction of the propulsion system's acceleration of a mass of gas. Group of answer choicesTrueFalse PreviousNext

The statement is True.

In aviation terminology, thrust is the force that propels an aircraft forward. It is generated primarily through the propulsion system, whether it be jet engines, propellers, or rotor systems. According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. When the propulsion system accelerates a mass of gas (such as air or exhaust gases from a jet engine), it produces a thrust force in the opposite direction.

In jet engines, this process occurs when air enters the engine, is compressed, mixed with fuel, ignited, and then expelled at high speed out of the engine. Likewise, in propellers, rotating blades push air backward, resulting in thrust. Therefore, the thrust experienced by the aircraft is a direct result of accelerating this mass of expelled gas. This fundamental principle is critical in aerospace engineering and helps us understand how aircraft manage to overcome drag and achieve flight.
