Turbomachine, has blower supplying tertiary flow to duct, where blower is driven in rotation by air entering or leaving another blower that supplies primary flow to compressor and secondary flow to another duct

摘要

The turbomachine (10) has a blower (12) supplying a primary flow (16) to a compressor (22) and a secondary flow (18) to a duct (40) extending around the compressor. Another blower (14) supplies a tertiary flow (20) to another duct (44) extending around the former duct. The latter blower is secured to a turbine wheel (46) rotatably mounted upstream of the compressor and upstream or downstream of the former blower, where the latter blower is driven in rotation by air entering the former blower or leaving the former blower.
