TURBOFAN ENGINE WITH COMPACT SYSTEM OF AIR TAKEOFF FROM BOOSTER COMPRESSOR

摘要

FIELD: engines and pumps.;SUBSTANCE: turbofan engine (10) comprises a fan (14), attached to a frame (32) of fan fixation inside a fan body (30). The booster compressor (16) is attached to the fan (14) inside a flow separator (34). The body (30) surrounds the fan (14) and the separator (34) and is located at a distance from the separator (34) to form an outer contour (36) between them. The frame of fan fixation (32) is located behind the booster compressor (16) and includes a row of struts (38), passing along the radius outside via an outer circuit (36) from a circular bushing (40), arranged between the booster compressor (16) and the high pressure compressor (18). The system (54) of air takeoff from booster compressor is located inside the separator (34) and includes an inlet channel (58) of the takeoff system, arranged between the booster compressor (16) and the bushing (40), and an outlet channel (60) of the takeoff system, arranged at the rear end of the separator (34) in front of struts (38).;EFFECT: increased efficiency ratio.;7 cl, 2 dwg
