The tuyere deployable telescopically, ice cream cones nested, for a motor - rocket

摘要

P & this system comprises a fixed part 10 and a series of segments can be moved with increasing diameters, which, in the retracted position of the system, are arranged concentrically around the nozzle is fixed. Each segment 16, 24 is fixed a set of panels of the aerodynamic 26, 28. These panels are arranged so as to be pushed towards the rear by the thrust of the engine exhaust gases - fuse, and they cause the segments towards the deployed position. In this position, the output surface of the assembly is much greater than that of the nozzle is fixed, which improves the performance of the rocket engine - / p
