Abstract
A variable geometry device is provided for synchronous control of flow of fluid at the compressor inlet and outlet of a turbine engine. The turbine engine includes a support housing, a compressor contained within the support housing, a set of variable inlet guide vanes and a compressed air outlet in which a pair of spaced walls define an annular and radially extending diffuser passageway. The inner end of the diffuser passageway is open to the compressor outlet while the outer end of the diffuser passageway is open to the combustion chamber for the turbine engine. A plurality of circumferentially spaced diffuser vanes are mounted to one of the diffuser walls and protrude across the diffuser passageway. An annular recessed channel is formed around the opposite diffuser wall and an annular ring with a hollow cavity is mounted within the channel. A motor is operatively connected to this ring and, upon actuation, displaces the ring transversely across the diffuser passageway to variably restrict the diffuser passageway. In addition, a plurality of variable guide vanes are provided in the inlet to the compressor and varied in synchronism with the ring.
