摘要： A dual-entry radial compressor rotor (140) has two sets of alternating full length blades (152a, 154b) and partial length blades (152b, 154b) on a symmetrical hub (144), with the par- tiallength blades (152b or 154b) on one hub side terminating at the rotor high velocity exit coincident with the full length blades (154a or 152a) on the other hub side, to smooth the gas velocity profile in the tangential direction. Aerodynamically shaped sawtooth-profiled reliefs (172) are provided in the hub radial portion between the blade tips to allow induced pressure differentials between the flow paths to smooth the axial velocity profile.

摘要： An aerodynamically tapered spike (60) is positioned for controlled axial movement in the conical portion (34) of a composite gas turbine engine diffuser (16) controlling engine air mass flow rate by adjusting diffuser area ratio at the entrance (38) to the conical portion (34). Also, a straight pipe transition diffuser portion (44) connects the conical portion (34) and a flat plate-type diffuser portion (50) and changes the velocity profile from an axially skewed profile (42) into a flat profile (48) at the entrance (52) to the plate-type portion (50). The spike (60) is fixed to an axially moveable rod (62) extending through an aperture (58) in the flat impaction wall (56) of the plate-type diffuser portion (50).

摘要： A recuperated gas turbine engine (10) has series connected low and high pressure compressor stages (30, 32) having independently rotatable shafts (44, 46). The turbine shaft (46), low pressure compressor shaft (44) and engine output shaft (28) are differentially coupled with a planetary gearing assembly (50), with a sprag clutch override (100) connection between the output shaft (28) and the low pressure compressor shaft (44) to limit the speed reduction of the low pressure compressor stage (30). A variable speed transmission (108) is connected between the low pressure compressor shaft (44) and the engine output shaft (28) to aerodynamically match the high and low pressure compressor stages (30, 32). A brake (124) is geared to the output shaft (28), a starter (126) is coupled to the low pressure compressor shaft (44), and the planetary gear ratios are selected to allow preferential acceleration of low pressure stage (30) relative to the high pressure stage (32) and the turbine (12) during start-up. The method of automatically reducing the air mass flow rate during part load operations follows a predetermined fuel flow schedule to maintain rated combustion temperatures.

摘要： A movable spike, variable entrance geometry annular pipetype diffuser has, for prevention and suppression of flow-induced vibrations, a gear assembly for imparting rotational motion about the axis of a rod member supporting the spike in the diffuser channel, and damper guides fixed to the spike and cooperating with guide slots in the diffuser housing for opposing the rotational motion to create a biasing torque between the spike and housing to increase rigidity and damping.

摘要： An inlet guide vane apparatus for the adjustable insertion and retraction of a guide vane into the inlet passage of a compressor and the adjustable varying of the flow direction of the fluid downstream of the vane body by varying the angle of attack of the vane body includes a longitudinal vane body protruding part way across the inlet passage of the compressor through an aperture in the inlet shroud, and a winglet attached to the end of the vane body extending inboard the compressor inlet shroud. The degree of insertion of the vane body into the passage may be controlled by a pneumatically actuated slidable plunger attached to the vane body and responsive to the compressor discharge pressure. The angle of attack of the vane body may be controlled by a rotatable plunger cylinder having a longitudinally extending groove engaging a pin radially extending from a lateral portion of the body of the plunger. The plunger cylinder can be rotated by a synchronizing ring that meshes with a bevel gear fixed to one end of the plunger cylinder. Alternatively, the plunger cylinder may be fixed and have a curved groove wherein the angle of attack can vary with the degree of insertion.
