Abstract: A filling device adapted for wetting or filling a component provided with an undercut, includes a mixing head for mixing a flowable, curable, filler and an outlet tube for feeding the flowable filler to or into a filling space in the component. An adjustable deflecting unit for changing the direction of flow F of the flowable filler is provided such that the filler emerging from the outlet tube can be deflected into an intended direction of flow.

Abstract: In an exemplary variable area nozzle, a fixed duct section has an inlet and an outlet oriented approximately perpendicular to the inlet. A controllable nozzle member is disposed adjacent the outlet of the fixed duct section. The controllable nozzle member has an area that is adjustable to maintain a substantially constant nozzle pressure ratio. The controllable nozzle member may include first and second flap doors hinged and pivotable in opposite directions between an open position and a closed position and that also may be hinged and pivotable in a same direction so thrust from gas exiting the nozzle is vectorable. When disposed in rotor tips of an aircraft capable of rotary wing flight and fixed wing flight, the variable area nozzle may maintain a substantially constant nozzle pressure ratio near an optimized nozzle pressure ratio as the aircraft transitions from rotary wing flight to fixed wing flight.
