ABSTRACT:
A jet pipe for jet propulsion in aircraft has in flow-series a first or fixed duct 13, a second duct 14 and a third duct 15. The second duct 14 is supported on the first duct 13 for rotation about a common axis 13A, 14A of these two ducts. The third duct 15 is supported on the second duct 14 for rotation about an axis 19A having an angle oblique the axis 14A of the second duct. A ring 30 is supported on the second duct 14 for rotation about the axis 14A thereof. A bracket 31 mounted on the ring 30 has a guide and slide connection 32,33 with the third duct 15. A single drive shaft 24, mounted on the fixed duct 13, is connected to rotate the second duct 14 and the ring 30 in opposite directions. The guide and slide connection effects a corresponding rotation of the duct 15 about the axis 19A. The resulting relative rotation of the ducts 14,15 results in the duct 15 moving so that the axis 15A thereof moves through an angle .beta. while remaining in a given plane 11A, 11B.
