COLD FLOW TUYERE OF A TWO SEPARATE FLOW DOUBLE FLOW TURBOREACTOR INCORPORATING A GRILLED PUSH INVERTER

摘要

The present invention relates to a cold flow nozzle of a split stream turbofan engine comprising an annular cowl element (27, 127, 227) movable in axial translation between an upstream retracted position for direct thrust engine operation. and a downstream extension position, and a grid thrust reverser (28, 128, 228) in the form of cylindrical ring sectors coaxial with said hood member, formed of radially oriented vanes, and axially spaced apart to provide between them radial guide passages, the bonnet member releasing in said downstream extension position said radial passages through the thrust reversal grids. The nozzle is characterized in that the radius of the ring sectors forming the grids (28, 128, 228) is not constant along the circumference of the hood member (27, 127, 227).
