JET ENGINE WITH VARIABLE GEOMETRY FAN NOZZLE AND THRUST REVERSER

摘要

The present invention relates to a jet engine (10), in particular for an aircraft, comprising an engine nacelle (22), a core engine (18) arranged inside the engine nacelle (22) with a core engine casing (20) surrounding the core engine (18) Core engine (18) a core stream (C) is feasible or guided, between the core engine housing (20) and the engine nacelle (22) extending bypass duct (17), wherein by the bypass duct (17) a side stream (B) is guided or guided, a thrust reverser (27), which is designed so that it deflects only the secondary flow (B) of the bypass duct (17) in the activated operating state, and a variable Nebenstromdüse (33), which for providing a variable exit surface (34) of the Nebenstromdüse (33) is formed and has variable shelves. In particular, in order to achieve the best possible weight savings, a single common actuator system is provided for the thrust reverser (27) and the variable bypass nozzle (33) provided so as to be capable of the thrust reverser (27) and the variable bypass nozzle (33) mechanically coupled to each other and decoupled from each other, for example, by the Schubumkehreinrichtung (37) is selectively connected and moved.
