ABSTRACT:
A nozzle for a hypersonic engine includes an axially displaceable mushroom-shaped central body. Two mutually opposing expansion flaps are provided which, when the flying Mach number is low, can be swivelled with respect to one another and, when the flying Mach number is high, can be swivelled apart. As a result, an extensive change of the divergence of the nozzle can be achieved while maintaining a high mechanical stiffness and a low leakage level.
