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 patented PERT (Planar Exit Rear Target) thrust reverser features two blocker doors that serve as the engine's exhaust exit during flight, and are deployed on landing for the reverse thrust function.
On the taxi director's signal, I placed my hand on the nosewheel-steering handle and gave a good shot of reverse thrust to back us out of the wire.
The Maximum Reverse Thrust (MRT) feature allows you to rotate the engine 180 degrees, adjust the trim and the motor performs in reverse.
