| 摘要 |
<p>A turbine engine is disclosed that is capable of operating in an emergency power mode, an air breathing auxiliary power mode and a bypass bleed environmental control mode. A valving system selectively admits compressed air into the compressor and turbine section from the stored air inlet, air breathing inlet or bypass bleed inlet depending on the mode of operation. The tri-mode operation is made possible by a unique two-way bypass ring having a plurality of axial passages communicating the stored air inlet and air breathing inlet with the upstream combustor inlet and a plurality of radial passages communicating the bypass bleed inlet with the downstream combustor inlet.</p> |
