Title:

GATE TYPE THRUST REVERSION DEVICE FOR TURBO FAN ENGINE CONTAINING DEFLECTION BLADE CONNECTED TO FIXED STRUCTURE

Document Type and Number:

Japanese Patent JPH10184454

Kind Code:

A

Abstract:

To reduce the occurrence of an unbalance of a gate during direct jet by a method wherein a distance between the downstream part of a deflection edge and the inner surface of a gate is maintained in a minimum as much as possible as reversion aerodynamic performance is ensured during reversion jet, and the length of a part situated upper stream from a gate from a revolution point is minimized.

In the thrust reversion device of a turbo fan engine incorporated in the outer wall of an annular pipe 15 during direct jet containing a revolution gate 7 constituting a barrier wall for deflection of a flop, a constant shape part 21 connected to the fixed structure of the reversion device is disposed in a cavity formed below a gate during direct jet and a deflection blade to improve decision of the direction of a reversion flow is provided.
