Thrust reverser for a jet engine with blockdoors and deflector vanes linked to the fixed frame

摘要

The thrust reversal system consists of a number of hinged doors (7) which form part of the outer wall of the by-pass flow duct behind the engine fan when closed, and are opened to deflect the flow outwards and forwards. The opening through which the flow is deflected is bounded at the forward end by a deflector edge attached to the engines fixed structure, and behind which is a deflector vane (8) which is designed to improve the orientation of the thrust reversal flow. The vane, which has an aerofoil section, is situated in the cavity beneath the forward end of the thrust reversal door when closed. In a variant of the design the system can have a series of deflector vanes which deploy as the door is opened.
