TURBINE THRUST REVERSER HAVING A DEVICE FOR RE-ORIENTATING THE GAS FLOW

摘要

The present invention relates to an improved thrust reverseer door structure having a deflector that will reduce the aerodynamic losses and thereby increase the operating efficiency of a turbofan engine. The deflector has a first portion that extends generally radially inwardly when the door is in its retracted position and a second portion extending in a downstream direction from the distal edge of the first portion. The downstream facing second portion is located adjacent the inner surface of a secondary-duct wall and serves to deflect the air passing through this annular space away from an inner, concave portion of the thrust reverser door. The deflector may also include aperatures in the first portion to allow passage of the thrust reversing gases when the door is in its extended position. A baffle may also be attached to the first portion so as to extend at an angle over the aperatures.
