Deflector doors with movable grille for a jet engine thrust reverser

摘要

The thrust reversal system comprises pivoting hollow doors which form part of the engine cowling when closed, and pivot to enter the jet flow and deflect part of it outwards. Each hollow door (3) acts as a scoop and incorporates a mobile deflector grille (23) with hinged vanes along its rear edge. The grille is located inside the door during normal flight and its pivot (24) is carried by the door's supporting structure.
