ABSTRACT:
A propelling nozzle for a hypersonic jet plane having movable upper and lower primary and secondary flaps assigned to the gas turbojet engine as well as to the ramjet engine, both engines being arranged axially above one another, their outlet ducts being separated by means of a partition extending in the downstream direction to the narrowest cross-section of the propelling nozzle. The nozzle flaps can place themselves against the end edge of the partition on both sides in a manner advantageous with respect to the flow in the transition area from the primary flaps to the secondary flaps. As a result, each of the two outlet ducts can advantageously, either alternatively or simultaneously, be closed or opened, while, at the same time, a narrow cross-section and a divergence of the propelling nozzle can be adjusted which are optimal for the respective flying Mach number.
