    Abstract: A propelling nozzle with a variable contour can be used in subsonic, supersonic and hypersonic aircraft. The variable contour of the nozzle extends between opposite primary and secondary flaps which are sealingly guided over the surface of the walls of a nozzle housing. The primary and secondary flaps are pivotally hinged upstream and downstream, respectively, of the nozzle housing. In addition, the secondary flaps are pivotally hinged on pivots of the primary flaps arranged on the side remote from the jet issuing from the nozzle and are connected by curved sections to the primary flaps so as to form a continuous or level aerodynamic contour.

    Abstract: The present invention relates to a low signature jet engine outlet comprising movable border segments forming at least one circular arc and being movable radially for controlling the form and area of the outlet, at least one stationary border element for defining the form and area of the outlet, and movable coupling means for connecting the at least one circular arc to the at least one stationary border element. The coupling means are movable along a connection part of the at least one stationary border element, and the connection part of the at least one stationary border element is substantially flat and extending in a substantially radial direction of the at least one circular arc.
