Clamshell type thrust reverser.
The method and means of reducing the landing run of an aircraft without excessive use of wheel brakes or any use of braking or tail parachutes. On piston and turboprop engines, it can be done by reversing the propeller pitch. In turbojet engines, it can be done by reversing the direction of the exhaust gas stream. In gas turbine engines, thrust reversal normally is accomplished by mechanical blockage, bucket-type doors (retractable ejector system), clamshell doors, etc.

The DGCA directed aircraft operators to develop safe operating procedures to land at any airport with minimal use of thrust reversal without compromising the safety and runway capacity.
The Navigator ensured the aircraft remained on-station and on-course while the pilots ran the checklist for "Engine In-flight Thrust Reversal!' Upon advancing the #3 throttle in accorda nce with step four of the checklist, the crew immediately noticed a sudden yaw and roll.
In designing the ultrahigh bypass turbofan, critical areas of interest include thrust reversal, interaction of the variable-pitch fan and the core engine, acoustics, fuel consumption reduction, and the mechanical integration compatibility of the variable-pitch mechanism and the fan drive gear system.
