Title:
THRUST REVERSING DEVICE FOR JET ENGINE
Document Type and Number:
Japanese Patent JPS52139816
Kind Code:
A
Abstract:
A thrust reverser for a turbo-fan engine is provided with a sleeve (28) which normally forms part of the fan outlet duct. When reverse thrust is required the sleeve is pushed rearwards by means of a jack and shuts off the duct outlet. An annulus (37) in the sleeve (28) houses a number of rings which form a cascade of blades (34). These blades are exposed to the air flow by the rearward movement of the sleeve (28). The air from the fan is then deflected by the cascade of blades and consequently exerts a reverse thrust on the aircraft.
