Abstract:

Apparatus for simplifying maintenance of gas turbine engines. Ordinarily, to remove a high-pressure compressor in a twin-spool engine, many components of must be removed, such as parts of a booster, in order to gain access to a mounting nut which is threaded onto a shaft supporting the high-pressure compressor. The removal is necessary because the nut must be extracted from the engine after disengagement from the shaft. Under the invention, this removal-of-components is largely eliminated, by providing a stowage location for the nut within the engine. The nut is removed, and then threaded onto a set of threads specifically provided for storage of the nut, and for nothing else.
