Abstract
A gas turbine power plant, especially for helicopters, includes a main engine and a reduction gear transmission forming a self-sufficient auxiliary modular unit. A compensating arrangement includes an articulated outer cover and a shaft section inside said outer cover connected for transmitting power and for compensating any position disalignment between the main engine and the helicopter main gear drive. The reduction gear transmission is directly, rigidly force-coupled to the helicopter main gear drive, and the compensating arrangement including the articulated outer cover and shaft section is located between the main engine and the reduction gear transmission, whereby the axial length spacing between the main engine and the helicopter main gear drive is substantially reduced.
Claims16
A gas turbine power plant, especially for a helicopter, comprising a main engine (1, 1') including fresh air intake means (10) and exhaust gas discharge means (62), a power transmission train including reduction gear transmission means (3, 3') for reducing an engine r.p.m., main gear drive means (2, 2') for transmitting engine power, shaft means forming part of said power transmission train, and compensating means (4, 4') for compensating any position disalignments between said main engine (1, 1') and said main gear drive means (2, 2'), means attaching said reduction gear transmission means (3, 3') directly to said main gear drive means (2, 2'), and means mounting said compensating means (4, 4') directly between an output of said main engine (1, 1') and an input of said reduction gear transmission means (3, 3') substantially axially and radially within one of said fresh air intake means (10) and said exhaust gas discharge means (62) for effectively reducing an installed length of said power plant so that a distance between said main engine (1, 1') and said main gear driving means (2, 2') is reduced substantially by the axial length of said compensating means (4, 4').
