Thrust reversal device for air-craft turbojets

摘要

The invention relates to thrust reversal devices for jet aircraft turboreactors and particularly for a turbo-fan type engine. The casing E surrounding the engine structure D comprises an intermediate section S3 formed by doors P4 pivoting about an axis 17-17' extending along a chord of passage CA so that the rear part of the door is short, which provides considerable clearance for the doors which may open up to 90 DEG , as well as an action of flux F1 flowing in the passage promoting opening of the doors. A jack 21 coupled to each of the doors acts between the fixed structure of the casing and the internal part of the door.
