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.
