1. Some variants also included one axial stage compressor for additional performance. 2. Vapor from this tank is compressed to a gage pressure of by the first-stage compressor . 3. The remaining vapor is compressed in a high-stage compressor to a gage pressure of about. 4. In a multi-stage compressor , at the high pressure stages, axial velocity is very small. 5. The engine features a single fan, a two-stage compressor and a two-stage turbine. 6. Of axial-flow design with 15-stage compressor and 7-stage turbine, it incorporated many modern features. 7. Because an all-axial design is employed, the final stage compressor rotor blades are amongst the smallest ever manufactured. 8. Each low-stage compressor is powered by a motor and each high-stage compressor is powered by a motor. 9. Each low-stage compressor is powered by a motor and each high-stage compressor is powered by a motor. 10. The five-stage compressor has four axial ( LP ) stages and one radial or centrifugal ( HP ) stage.
