Air suction arrangement for aircraft, has branch line to draw bleed air from high-pressure region of engine so as to drive turbine of turbo-supercharger

摘要

#CMT# #/CMT# The suction arrangement has suction surfaces in critical flow areas. A suction pipe (23) is connected between the suction surface and a compressor (24) of a turbo-supercharger (2). A branch pipe (10) is connected between a high-pressure region (P) of an engine (1) to draw bleed air used for driving a turbine (20) of turbo-supercharger. The air from the boundary layer is drawn by the suction pipe using suction force of the compressor. #CMT#USE : #/CMT# For use in aircraft. #CMT#ADVANTAGE : #/CMT# Achieves highly efficient power conversion and prevents power losses in operating states in the suction of the air from the boundary layer is not required. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a cross sectional view of the aircraft with air suction arrangement. 2 : turbo-supercharger 10 : branch pipe 20 : turbine 23 : suction pipe 24 : compressor P : high-pressure region.
