A bypass air valve for a gas turbine engine is provided which includes a liner, a strap, and means for selectively actuating the valve. The liner includes an inner radial surface, an outer radial surface, a plurality of first regions, and a plurality of second regions. Each first region includes a plurality of first apertures. Each second region includes a plurality of second apertures. The strap includes a plurality of openings and a plurality of third regions. Each third region includes a plurality of third apertures. The valve may be selectively actuated into an open or a closed position. In the open position, the first regions are substantially aligned with the openings and the third regions are substantially aligned with the second regions. In the closed position, the first regions are substantially aligned with the third regions and the second regions are substantially aligned with the openings.

[ We claim:] [1.] A bypass air valve for a turbofan gas turbine engine, comprising:a liner, having an inner radial surface, an outer radial surface, a plurality of first regions, each first region including a plurality of first apertures, and a plurality of second regions, each second region having a plurality of second apertures;a strap, surrounding said liner, said strap having a plurality of openings and a plurality of third regions, said third regions including a plurality of third apertures;an actuator, for selectively actuating said strap relative to said liner;wherein said valve may be selectively actuated into an open position where said first regions are substantially aligned with said openings, thereby providing a first flow path for bypass air through said valve via said openings and said first apertures, and said third regions are substantially aligned with said second regions thereby providing a second flow path for bypass air through said valve via said third apertures and said second apertures; andwherein said valve may be selectively actuated into a closed position where said first regions are substantially aligned with said third regions, thereby providing a third flow path through said valve via said third and first apertures, and said second regions are substantially aligned with said openings, thereby providing a fourth flow path through said valve via said openings and said second apertures.
