SWINGING-DOOR THRUST REVERSER WITH MONITORED LEAKAGE DISCHARGE

摘要

bypass turbojet engines. SUBSTANCE: device has swinging doors integrated with external secondary-flow channel wall in forward thrust mode that function to oppose gas flow deflection in thrust reversal mode. At least one swinging door has passage in its rear zone along flow path for leakage flow whose geometry allows for passing monitored leakage flow in desired direction in thrust reversal mode; it also has means for shutting off mentioned passage in forward-thrust mode so as to ensure continuous or uninterrupted surface of secondary-flow channel; passage fully covers inner and outer parts of door; leakage gas flow goes towards rear part of door. EFFECT: reduced or fully eliminated resultant forward thrust of secondary-gas leakage discharge. 19 cl, 27 dwg
