Optimized power transmission method and structure between helicopter auxiliary power motor and main engine

摘要

The present invention aims to optimize the entire traction system available to a helicopter by using an auxiliary engine to supply energy to the helicopter equipment and accessories connected to the engine. In an embodiment of an energy-optimized transmission structure for carrying out the present invention, the main engine (1, 1 ') and the APU device (8) such as an auxiliary engine are connected to the main engine (1, 1'). Is connected to the reduction gear box (6) and to the accessory gear box (7) for mechanical, electrical and / or hydraulic power take-off, and for the APU device (8) at least one power conversion member (83, 84). , 11) connected to the gas generator (2; 81). The power conversion member (83, 84, 11) of the APU device (8) is connected to equipment and accessories by a reduction gear box (6) and / or an accessory gear box (7) of the main engine (1, 1 '). .
