摘要： A gas generator having a double entry low pressure centrifugal compressor, a single entry high pressure centrifugal compressor and a radial inflow turbine positioned coaxially and coupled for interdependent rotation by a single shaft assembly for the double entry compressor mounted to the generator frame using a plurality of rigid hollow cross-over ducts which also carry diffused compressed air to the high pressure compressor, where the single shaft assembly uses two shaft portions connected by an expansible coupling having a helical spline torque transmitting device to allow the double entry compressor rotor to "follow" compressor housing axial position changer and to maintain a close running clearance despite thermal expansion in the structure between the low pressure (LP) and high pressure (HP) compressor portions of the gas generator.

摘要： The use of externally-pressurized porous media in shaft sealing for turbomachinery is provided for single seals, tandem seals, double-opposed seals, and a ventless seal. These arrangements provide for significant benefits, such as the following: (a) external pressurization allows frozen seal faces to lift open before rotation, (b) pressure is distributed uniformly across the seal face, as opposed to allowing leakage to pass over it, (c) low flow rates of injected gas are possible, (d) the seal faces are self-defending due to the uniform pressure in the gap, and (e) complete elimination of venting process gas is possible. By employing externally-pressurized porous media sealing, a drastic simplification of seal design, as well as gas treatment and seal panel design, is possible.
