Disclosed is a thrust reverser for diverting the bypass flow of a bypass turbojet, comprising shiftable elements or buckets (17). At least one downstream portion of each bucket covers, in the direct flow, a portion of a fixed structure (20) which forms the outer wall of the bypass flow canal, the outer surface of said bucket (17) forming a portion of the outer pod surface. Attachment, retention, and guidance during the displacement of the bucket (17) are ensured by a system of connecting rods placed upstream (36) and downstream (27), said rods (27, 36) being situated on the fixed structure of the pod and disposed in the direct flow inside the thickness of the fixed beam that separates two buckets (17).

 Appl.No PCT/FR1995/001698 Applicant SOCIETE HISPANO SUIZA Inventor GLOWACKI, Pierre, Antoine
Shield for protecting the outer fairing (3) of a turbomachine. Said shield consists of a ring of ductile material retained by fastening means with fairly easy breaking properties. When a piece of the rotor (17) comes loose accidentally and impacts said shield, the denting caused ruptures some or all of the fastening means. This allows the shield (9) to undergo considerable deformation thus enhancing its energy absorbing capability.

 Appl.No PCT/FR2000/003183 Applicant SNECMA MOTEURS Inventor DUQUENNE, Catherine, Dominique, Béatrice
The invention concerns a shot blasting method called ultrasonic using a mist of microbeads inside a working chamber (30c), and more particularly a method for shot blasting workpieces (21) on a wheel (19), such as the vanes of turbo-machine blades on a rotor. Said method is characterised in that it consists in bringing the periphery of the wheel (19) simultaneously in front of the orifices of at least three chambers with limited clearances E1 and E2, at least one chamber being active, at least two chambers being passive, the wheel being then rotated, and the microbeads are removed from the passive chambers and the active chambers are fed with microbeads. The invention also concerns a shot blasting machine for implementing said method.

The invention concerns a thrust reverser for a turbofan comprising doors (7) integrated in direct jet in the external wall of the ring-shaped conduit (15) and pivoting by the operation of a control actuator (8) to constitute deviation obstacles for the reversed flow. Two primary locks (20a, 20b) integral with the reverser fixed upstream structure and arranged on either side of the central door line (7) are simultaneously in contact with the door (7) in flight configuration and retain said door (7) without protruding relative to the pod internal and external lines.
