engine thrust的意思|示意

Engine thrust is a force created by an aircraft engine that propels the aircraft forward. The thrust produced by an engine is the primary force that keeps an aircraft in the air.

When an engine creates thrust, the engine takes in air and releases it in the same direction as the plane is traveling. This change in momentum causes an equal and opposite reaction, pushing the plane forward, allowing it to move forward. This is known as Newton’s third law of motion, which states for every action there is an equal and opposite reaction.

The thrust produced by an engine depends on the speed at which the engine exhausts the air. The faster the air leaves the engine, the greater the thrust. Jet and turbo-prop engines exhaust the air at high speeds, providing them with more thrust than piston engines.

Engine thrust is measured in pounds, and the amount of thrust an engine produces is determined by several factors, such as the size and type of engine, as well as the power output and the rate at which fuel is consumed.

Engine thrust is very important to an aircraft’s performance. The ability of an aircraft to accelerate, climb, and reach cruising speed is determined by the amount of thrust it produces. The amount of thrust an engine produces is also used to determine the maximum weight an aircraft can carry.

In summary, engine thrust is the primary force that propels an aircraft forward. The amount of thrust an engine produces is determined by the speed at which the exhaust air is released, as well as the size and type of engine, and the power output and fuel consumption rate. Engine thrust is important for aircraft performance, and it affects the maximum weight an aircraft can carry.
