  • Patent number: 4697981
    Abstract: A turbine construction in which the axial loading on the rotor including the compressor and turbine resulting from cooling air pressure in the compartment between the compressor and turbine is balanced by making the compressor and turbine areas exposed to the cooling air of equal area as by having the seals at compressor and turbine ends of the compartment equal in radius with respect to the air of the rotor.

  • Patent number: 4668164
    Abstract: A stator assembly 18 for a gas turbine engine is disclosed. The stator assembly includes an engine case 24 and a wall 26, such as a wall that includes an array of stator vanes 42. A high pressure region 74 (cooling chambers) extends between the wall and the engine case. The cooling chambers 74 are in flow communication through a leak path with a working medium flow path 14. An annular outer support 56 bounding the chambers beneath the vanes forms with the vanes an intermediate chamber 132 through which the leak path for cooling fluid passes. The annular support further includes a plurality of orifices 94 for diverting flow away from the leak path to lower the pressure of the intermediate chamber. In one embodiment, the chamber is formed in part by an annular groove 84 in the support and a plurality of flanges 124 associated with the vanes. The flanges are urged rearwardly into sealing contact with the annular support.

  • Patent number: 4268221
    Abstract: A compressor structure for a gas turbine engine capable of enhanced active clearance control within the compressor is disclosed. Various construction details which enable the discharge of cooling air against the compressor case and which minimize thermal distortion of the case are developed. The concepts are applied to a longitudinally split compressor case and include an external bleed manifold of circular cross section which extends across the longitudinal split in the case. Cooling air is dischargeable beneath the manifold to cool the case structure. Heat shields are provided in access ports to the manifold to inhibit heat transfer to the compressor case at the local regions of the ports.
