| 摘要 |
The present invention provides a supercharged open cycle gas turbine engine comprising a core engine for generating shaft power output, said core engine includes a multi-stage compressor, the first stage of which being a rotary ram compressor or a rotary ram-in compressor; a supercharger for increasing the pressure of intake air of the core engine, said supercharger includes a rotary ram-in compressor and a turbine driven by gases discharged from the core engine and having variable-area nozzle assembly; operator controlled means for elective bleeding of variable part of the exhaust gases discharged from the core engine and supplied to the supercharger turbine; at least one pressure sensor for detecting the degree of rise in the pressure of air supplied by the supercharger's compressor; means for adjusting the area of the nozzles of the supercharger's turbine according to the detected degree of rise in the air pressure; and means for adjusting the rate of fuel supply to the core engine according to the pressure level of air supplied by the supercharger's compressor.
