Abstract: A nozzle arrangement for a gas turbine engine includes an engine nozzle and an ejector nozzle arranged axially downstream thereof. A gap S is formed between the outlet of the engine nozzle and the inlet of the ejector nozzle, and a flange which reduces the gap S is arranged at the outlet of the engine nozzle.

Abstract: A speed brake for aircraft in the form of a flap is provided. The flap can be extended into the air stream for increasing the flow resistance of the air. An extension is attached on the upper side of the flap on one side with respect to the center line of the flap, and the extension is attached in such a manner that in the retracted state of the flap, the extension extends along the flow direction of the air.

Abstract: A propulsion system for an aircraft capable of hypersonic flight combines a turbo-jet with a ramjet which are so arranged that the ramjet or jets are located directly adjacent to the aircraft body while the turbo-jet or jets are located away from the aircraft body so that the ramjet or jets is placed between the turbo-jets and the body. This arrangement makes the turbo-jets much more accessible for maintenance and exchange work. Both types of engines have a common air intake which is provided with flaps capable of guiding the body boundary layer through the ramjet when the latter is not in operation. When the ramjet is in operation, the air intake flaps form the air intake in such a way that boundary layer turbulent air is mixed with undisturbed incoming air for the ramjet while the air inflow to the turbo-jet is closed off altogether.
