TELESCOPICALLY DEPLOYABLE NOZZLE SYSTEM WITH NESTED CONES FOR A ROCKET ENGINE

摘要

P This system comprises a fixed part 10 and a series of displaceable conical segments of increasing diameters, which, in the retracted position of the system, are arranged concentrically around the fixed nozzle. A set of aerodynamic drive panels 26, 28 is attached to each segment 16, 24. These panels are arranged so as to be pushed back by the thrust of the exhaust gases from the rocket engine and they drive the segments to the deployed position. In this position, the outlet surface of the assembly is much greater than that of the fixed nozzle, which improves the performance of the rocket engine. /P
