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 means of gears to rotate the second pipe section independently of rotation of the first pipe section. Actuating devices mounted on the engine jet pipe and providing a linear movement are coupled by way of actuating arms extending externally of the pipe sections to the nozzle actuated skirt for control of the nozzle flaps.
