摘要： A bypass turbofan gas turbine engine (10) is started by means of electric starter motor (26) mounted directly about a downstream end or upstream of the low pressure spool (12) of the engine. This causes air to be driven by a fan (16) through a bypass duct (32) around the engine casing (28). Closures (34) close to substantially seal an outlet of the bypass duct (32), and the air is directed into a combustion chamber (24) of the engine and through the turbines (22,23), causing the high pressure spool (14) to pick up speed for starting.

摘要： A gas turbine engine (2) comprises a fan unit (4, 18, 36, 42, 44, 46) in flow relationship with an engine core and a bypass duct, of which said engine core and bypass duct (16) are in parallel flow relationship with each other. The engine core comprises a compressor (6), a combustor (8) and a turbine (10), with an inner casing (12) provided around said engine core which defines the engine core intake (32). The bypass duct (16) is defined by an outer casing (14) radially spaced apart from the fan unit (4, 18, 36, 42, 44, 46) and the inner casing (12) along at least part of the length of the gas turbine engine (2). Bypass air compression means (28) are provided such that, under substantially all engine power conditions, air at exit from the bypass duct (16) is at a greater pressure than air delivered to the engine core intake (32).
摘要翻译：燃气涡轮发动机（2）包括与发动机芯和旁通管道成流动关系的风扇单元（4,18,36,44,44），其中所述发动机机芯和旁路管道（16）处于平行状态流动关系。发动机机芯包括压缩机（6），燃烧器（8）和涡轮机（10），其中设置有围绕所述发动机机芯的内壳（12），所述内壳限定了发动机机芯进气口（32）。所述旁路管道（16）由与所述风扇单元（4,18,36,44,46）和所述内壳体（12）径向间隔开的至少部分长度的外壳（14）限定，燃气涡轮发动机（2）。旁路空气压缩装置（28）设置成使得在基本上所有的发动机功率条件下，从旁路管道（16）出口的空气处于比输送到发动机芯进气口（32）的空气更大的压力。
