What is thrust reverser?

A thrust reverser is a device on an aircraft engine that redirects the thrust produced by the engine in the opposite direction, typically to slow down the aircraft upon landing. This is achieved by changing the direction of the airflow, using mechanical components or aerodynamic surfaces, to create reverse thrust.

Thrust reversers are commonly found on jet engines and turboprop engines, and can be deployed either automatically or manually by the pilot. They are a crucial safety feature during landing, helping to reduce the runway distance required for the aircraft to come to a stop and improving overall braking efficiency.

There are several types of thrust reversers, including clamshell doors, cascade vanes, target reversers, and cold stream reversers, each with their own unique design and operation. Thrust reversers are often integrated into the engine nacelle or mounted externally on the aircraft as separate assemblies.

Overall, thrust reversers play a vital role in enhancing the safety and performance of modern aircraft during landing and ground operations.
