摘要: A fan-turbine rotor assembly for a tip turbine engine includes an inducer with an inducer inlet section and an inducer passage section in communication with a core airflow passage within a fan blade. Each inducer inlet section is canted toward a rotational direction of the fan-turbine rotor assembly such that the inducer inlet section operates as an air scoop during rotation of the fan-turbine rotor assembly. Both axial and centrifugal compression of the airflow occurs within the inducer passage section to effectively pump the airflow through the inducer section and into the core airflow passage.

摘要: Air (19, 119) captured from the tips (25, 125) of a compressor (10, 110) of a gas turbine engine is diverted from the engine core (22, 122) and can be collected for auxiliary uses. Gas path separation can be achieved using part-span shrouded compressor blades or using blade tip cut-outs (24) conforming to an airflow dividing annular shroud. In a preferred application for the present invention, the gas turbine engine is the auxiliary power unit of an aircraft.

摘要: A gas turbine engine (2) comprises a fan unit (4,18,36,42,44,46) in flow relationship with an engine core and a bypass duct, of which said engine core and bypass duct (16) are in parallel flow relationship with each other. The engine core comprises a compressor (6), a combustor (8) and a turbine (10), with an inner casing (12) provided around said engine core which defines the engine core intake (32). The bypass duct (16) is defined by an outer casing (14) radially spaced apart from the fan unit (4,18,36,42,44,46) and the inner casing (12) along at least part of the length of the gas turbine engine (2). Bypass air compression means (28) are provided such that, under substantially all engine power conditions, air at exit from the bypass duct (16) is at a greater pressure than air delivered to the engine core intake (32).

摘要: A compression system endwall bleed system having a plurality of bleed slots (41) formed in a mechanical housing (38) downstream of a rotating shrouded rotor (35). In one embodiment, the plurality of bleed slots (41) bleed off a separated tip boundary layer to relieve back pressure associated with this blockage. A sealing structure (47, 48) downstream of the shrouded rotor (35) is utilized to minimize working fluid leakage ahead of the plurality of bleed slots (41).
