摘要

The present invention at least one of the accessory (1, 2) and a rotor of a rotary wing aircraft (5) individually or in combination to the present invention relates to the transmission mechanism between the engine members (3, 4) with driving. A main shaft that drives the rotor (5) and (7), the accessory from the engine member (3) are selected for the drive of the accessory (1, 2) to the intermediate shaft between the drive shaft portion 12 with the 13 There is interposed. The intermediate shaft 13 is connected directly to the main shaft 7, also, pre-engagement with the wheel (16, 17) through the accessory drive gear 23, the gear 23 is in the engine member (3) by, or rotor, and (5) in the position for driving together can be driven by the main shaft 7, the rotor is driven like a windmill or in case of a failure by the other two engine members aenjin member 4 .
