Abstract: An arrangement is disclosed for distributing and supplying and removing a coolant to and from a wall of a turbine engine, in particular a turbine dynamic jet engine, which is subjected to the flow of a hot fluid and has cooling channels which can be acted upon by the coolant and which are arranged substantially parallel to one another in the wall. The arrangement includes tube guides which are spatially separated from one another and connected to the wall, a casing of each tube guide having a longitudinal slot, each tube guide being attached on an inlet or outlet side to the respective cooling channels by way of the longitudinal slot and apertures in the wall, and a soldering or welded seam connecting the tube guides to the wall along the respective longitudinal slot.

Abstract: A propelling nozzle has upper and lower primary and secondary flaps which are disposed opposite one another at a mutual distance and which are sealingly movably guided between lateral wall portions of a four-cornered nozzle housing. The primary flaps are arranged pivotally about a fixed axis of rotation on the nozzle housing. The secondary flaps, in each case upstream of levers non-rotatably connected with the primary flaps, are pivotally linked to pivots situated on the side facing away from the nozzle flow. The secondary flaps change into the primary flaps with a surface section which is bent concentrically with respect to the pivots. The primary and secondary flaps are arranged in a four-cornered nozzle housing which is itself closed in. In each case the secondary flaps are arranged on the nozzle housing in an axially movable and angularly adjustable manner at the downstream end. The levers are formed on interior sections which are bent away from the primary flaps in a toggle-lever-type manner.

Abstract: The proposal is for a thrust nozzle for aircraft fitted with jet engines especially for lateral thrust vector control, in which the upstream ends of at least two flaps (8, 12) actuated via lever-like adjusters are arranged to pivot simultaneously at different angles of rotation about spindles running across the nozzle axis (20) and between walls (22, 23) running substantially parallel to the nozzle axis of a square nozzle housing in such a way that, with a permanently convergent nozzle contour, a narrowest cross-section is formed between the flaps (8, 12) at the outlet side; one end of each lever-like adjuster (28, 29) is to engage in downstream ends of the flaps, said adjusters being arranged at their movably mutually coupled other ends to travel in a guide path (30) which is curved so as to produce continuously different flap rotation angles; one or more narrowest cross-sections can either be kept continuously constant or change dependently upon the jet deflection angle.

Abstract: Turboramjet engine having a variable air intake, a ram air duct annularly enveloping the basic turbojet engine, and shutoff devices with which the ram air duct is energized with air when the basic turbojet engine is shut off and with which the basic turbojet engine is energized with air when the ram air duct is shut off. An air tract communicates with the air intake on a tubular duct carried axially on the basic turbojet engine and expands to an annular inlet section to the ram air duct. The shutoff devices are associated at least on the inlet side with quadrilateral sections of the tubular duct. As shutoff means for the inlet flow, use is made of an axially adjustable and internally swept sleeve valve and at least one flap that can be pivoted against a partial inlet area of the inlet section, which flap seals off the sleeve valve in lid-fashion when the inlet section is in a jointly exposed position.

Abstract: An integrated turboramjet engine has an axially slidable inlet cone, a rigid guide ring arranged concentrically outside the inlet cone, and a lock ring which can be slid axially against the inlet cone, whereby the air volume flowing into the air inlet can be introduced alternately into a turbo-inlet duct or a ram-air inlet duct in a low-loss and flow-promoting manner.

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.

Abstract: A change-over arrangement for an integrated turboramjet engine has a guide ring which can be displaced in the axial direction and an annular cone which can be displaced against the guide ring. In the turbo-operation, the annular cone is in its front position and the guide ring is in its rear position closing off a ram air inlet duct, and in the ramjet operation, the annular cone, in its rear position, closes off the turbo-inlet duct, and the guide ring opens up the ram air inlet duct. As a result, a low-loss introduction of the air current can take place into the turbo-inlet duct or into the ram air inlet duct, without, at the same time, requiring disadvantageous enlargements of the diameter of the outer casing of the engine.

Abstract: A gas turbine jet engine is disclosed with a fan delivering into a bypass duct to generate mainly propulsion thrust, and with a thrust reversing device having flaps which for reverse thrust operation pivot into the fan air stream and cooperate with an axially extended extreme section of the outer wall of the bypass duct to uncover delection ports arranged at breakthroughs in the outer wall. The extreme section of the outer wall and the thrust reverser flaps are linked one with the other for relative movement between them such that in a first phase of actuation relative to a fixed extreme nozzle section, the extreme section provides an additional fan nozzle area which communicates with the inlet flow areas formed by the flaps relative to the bypass duct.

Abstract: A jet deflecting device has a first rotatable pipe section connected to the nd of an engine jet pipe and a second pipe section rotatably connected to the end of the first pipe section. Nozzle flaps are provided at the end of the second pipe section, and coupled to be moved inwardly and outwardly in response to axial movement of a nozzle actuating skirt slidably mounted at the end of the second pipe section. A first drive motor on the stationary jet pipe directly rotates the first pipe section by way of driving gears. A second drive motor is coupled by gears to rotate the second pipe section independently of rotation of the first pipe section, and a third drive motor is provided for rotating an angular gear carrier on the second pipe section independently of the angular position of the two pipe sections. An angle drive mechanism is provided for converting rotational movement of the angular gear carrier to axial movement of the nozzle actuating skirt for control of the nozzle flaps.
