A turbine engine emergency power system includes low and high pressure spools, the lower pressure spool including a low pressure compressor. A turbofan is coupled to the low pressure spool. The turbofan drives the low pressure spool in a windmill condition in which the low pressure turbine fails to provide rotational drive to the turbofan. A generator is rotationally driven by the low pressure spool in the windmill condition. A gear train is used to increase the speed of the generator in one example. In one example embodiment, a centrifugal clutch is use...
What is claimed is: 1. A turbine engine emergency power system comprising: a first spool including a turbine; a turbofan coupled to the first spool, the turbofan driving the first spool in a windmill condition in which the turbine fails to provide rotational drive to the turbofan; a generator selectively rotationally driven by the first spool in the windmill condition; and a coupling arranged between the first spool and the generator for selectively driving the generator with the first spool in the windmill condition, wherein the coupling includes a cen...
