Abstract (en)
[origin: WO2011144837A1] Said thrust reverser, having gratings and intended for an airplane dual flow jet engine nacelle, includes: a front frame (9) holding a plurality of cascades (7); a cowl (13) that is slidably mounted between a direct jet position, in which said cowl covers said cascades (7), and a reverse jet position, in which said cowl uncovers said cascades (7), said cowl (13) including a substantially annular diaphragm (17) that is placed edge-to-edge with said front frame (9) and radially inside said cascades (7) when said cowl (13) is located in a direct jet position; - thrust reversal flaps (31) that are pivotably mounted onto said diaphragm (17) between a direct jet position, in which said flaps enable the flow of cool air downstream from the thrust reverser, and a reverse jet position, in which said flaps direct said cool air (F2) to said cascades (7); and cylinders (19) for actuating said cowl (13) between the direct and reverse jet positions thereof. Said thrust reverser is characterized in that the upstream ends of said cylinders (19) are to intended be mounted onto a stationary portion of said nacelle and in that the downstream ends of said cylinders are mounted onto the upstream edge (27) of said diaphragm (17).
