METHOD FOR PROTECTION OF FIRE-FIGHTING AMPHIBIAN AIRPLANE POWER PLANT AGAINST FOREIGN OBJECTS ENTERING AND VORTICES DESTRUCTION AT AIR INTAKE OF DUAL-FLOW TURBOJET ENGINE (DFTJE)

摘要

FIELD: transport.;SUBSTANCE: invention relates to aircraft, in particular, to methods of operation and protection of dual-flow turbojet engines of fire-fighting amphibian airplanes against foreign objects entering. Protection method consists in blowing out high-pressure streams in front of dual-flow turbojet engine air intake. Blowing out is performed by water taken from water tanks of fire-fighting amphibian airplane and creates dynamic water curtain aimed forward and down from lower air intake half-ring and in emergencies - additionally from engine spinner along periphery towards fan contour.;EFFECT: higher efficiency of amphibian airplane dual-flow turbojet engines protection.;3 dwg
