Thrust Reversal consist of 2 words. Thrust and reversal. This is a process adopted to reduce the aircraft velocity during landing. It is a type of braking system. The braking system in an aircraft consist of:
1. Landing Gear brakes.
2. Ground Spoilers
3. Thrust reversal.
So while talking about the thrust reversal, the type of aircraft has an important role to play.
For the propeller driven aircraft the reverse thrust is achieved with the appropriate change in the blade angle.
However for a jet engine the reversal of the thrust come in basically 2 major types:
1. Reversal by the use of hot exhaust.
2. Reversal by the use of cold bypass air.
Classification in terms of mechanism used are:
1. Target (bucket) type
Operated With hydraulics in turbojet engine
2. Clamshell (Cascade) type
Operated with Pneumatics in Low bypass turbofan engine
3. Coldstream type
The cold stream reverser system is activated by an air motor in High bypass turbofan engine
