| description | The title of the invention is increasing the surge margin via shaft power transfer. In a gas turbine engine 101 of the type having a high-pressure (HP) spool and a low-pressure (LP) spool, methods ofincreasing surge margin and compression efficiency at a given thrust are provided. One method increases compression efficiency and comprises transferring mechanical power from the HP spool to the LP spool to reduce a corrected speed of a HP compressor 105 therein and raise a working line of a LP compressor 104 therein. Another method increases surge margin and comprises transferring mechanical power from the LP spool to the HP spool to increase a corrected speed of a HP compressor 105 therein and lower a working line of a LP compressor 104 therein.
本发明题为"经由轴功率传输增加喘振裕度和压缩效率"。本发明在具有高压(HP)滑阀和低压(LP)滑阀的类型的气体涡轮引擎101中提供了在给定推力下增加喘振裕度和压缩效率的方法。一种方法增加了压缩效率，并且包括将机械功率从所述HP滑阀传输到所述LP滑阀，以减小该气体涡轮引擎中的HP压缩机105的校正速度并提高该气体涡轮引擎中的LP压缩机104的工作线。另一种方法增加了喘振裕度，并且包括将机械功率从所述LP滑阀传输到所述HP滑阀，以增加该气体涡轮引擎中的HP压缩机105的校正速度并降低该气体涡轮引擎中的LP压缩机104的工作线。 |
