Abstract:
1. A turbomachine comprising: an intermediate casing between a low-pressure compressor and a high-pressure compressor; an electrical generator/starter including a rotor driven by a shaft of the high-pressure compressor around a longitudinal axis of said turbomachine, said electrical generator/starter including a stator carried by said intermediate casing an annular housing that houses said electrical generator/starter, said annular housing being mounted around the longitudinal axis of said turbomachine in an upstream enclosure of the turbomachine, said upstream enclosure being situated inside the intermediate casing and containing oil, the annular housing of the generator/starter being supplied with compressed air from said low-pressure compressor, wherein the annular housing comprises a first connector that couples said housing to electrical cables mounted in structural arms of the intermediate casing, said first connector being leaktight and extending inside a chamber delimited by the housing and by the intermediate casing and supplied with said compressed air from said low-pressure compressor, and wherein said annular housing comprises a rotating housing element coupled to said rotor of said electrical generator/starter and being driven by said shaft of said high-pressure compressor around said longitudinal axis of said turbomachine, wherein said annular housing further comprises stationary housing element coupled to said stator of said electrical generator/starter and to said intermediate casing, and wherein said rotating housing element and said stationary housing element being coupled to each other via rotating seals so as to form said annular housing.
