Abstract
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.degree., 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.
