What is the function of an aircraft's thrust reverser?

The function of an aircraft's thrust reverser is primarily to redirect the engine's thrust forward to help slow down the aircraft after landing. This system operates by changing the direction of the engine's exhaust, which provides a decelerative force that assists in reducing landing roll distance. When an aircraft lands, reducing speed quickly and efficiently is critical for safety, and thrust reversers contribute to that by allowing the aircraft to decelerate more rapidly than it would by relying solely on wheel brakes.

Thrust reversers are particularly beneficial for larger aircraft, where the landing speeds are higher, and the distance required to come to a stop needs to be minimized. By deploying the thrust reversers, the aircraft can safely and effectively slow down, enhancing overall landing performance.
