Abstract

The nozzle 1 of the jet unit is extended by a diverging part 2. Between nozzle 1 and part 2, immediately behind the nozzle outlet 3, four segmental spoilers 4 are arranged. By operating the control bars 8 the spoilers can be pushed into the nozzle as shown in the diagram below. A ring chamber 9 is divided by radial walls 9a into four sectors opening into the diverging part 2 of the nozzle by an annular slot 10. Each sector may be provided with air pressure by opening a valve 12 in the tube 11. When all four spoilers project into the nozzle the jet leaves the nozzle in its axial direction. By retracting one of the spoilers 4 the jet is deflected to the side of this spoiler. This deflexion is increased by providing the adjacent chamber sector with air pressure. Each valve 12 is coupled to the corresponding spoiler control bar 8 by a lever 13.
