TWIN-DOOR THRUST REVERSER

摘要

A thrust reverser for aircraft turbojet engine nacelle includes at least one upstream door and a downstream door. The upstream and downstream doors move in concert between a direct jet position and a reverse jet position. In the direct jet position, two doors are closed, and in the reverse jet position the two doors are open and able to deflect a part of a cold air flow circulating inside the nacelle. The thrust reverser further includes a curved downstream edge of the upstream door to make adapted a part of cold air flow circulating between an upper camber of the upstream door and a lower camber of the downstream door.

1. A thrust reverser for an aircraft turbojet engine nacelle, comprising:
at least one pair of doors, the at least one pair of doors comprising an upstream door and a downstream door which move in concert between a direct jet position and a reverse jet position, wherein in the direct jet position, the upstream and downstream doors are closed, and in the reverse jet position, the upstream and downstream doors are open and able to deflect at least part of a cold air flow circulating an inside the nacelle; and adapting means configured to adapt a part of the cold air flow circulating between an upper camber of the upstream door and a lower camber of the downstream door, the adapting means comprising means for reducing effects of a separation of a boundary layer of the part of the cold air flow circulating between the upper camber and the lower camber, the boundary layer being located on the upper camber of the upstream door.
