METHOD FOR PREVENTING INGRESS OF FOREIGN BODIES INTO AIR INTAKE OF GAS-TURBINE ENGINE Russian patent published in 2000 - IPC

Abstract RU 2156369 C1

FIELD: gas-turbine engine. SUBSTANCE: method for preventing ingress of foreign bodies into engine air intake during take-off and landing of flying vehicle involves blow-out of high-pressure air upstream of air intake and organizing its continuous flow in the form of conical jet along engine axis away from air intake. In this way, reduced amount of high-pressure air is taken off high-pressure condenser for air intake protection. EFFECT: improved efficiency. 1 dwg
