초록

로터크래프트의 동력전달장치용 기어박스는 엔진에서 생성된 동력을 승하강 및 전진 비행을 위한 팬 및 푸셔로 전달하며, 사용목적에 따라 메인기어박스, 보조기어박스로 구분된다. 로터크래프트 동력전달장치용 기어박스의 주 설계 목표는 주어진 요구사항(전달동력, 장착공간 등)을 모두 만족시키는 범위에서 가능한 경량화 설계를 하는 것이다. 특히 기어박스는 같은 기능을 하더라도 시스템 구성에 따라 전체 중량이 크게 달라질 수 있기 때문에 경량화를 위해서는 초기 개념 설계가 매우 중요하다. 본 연구에서는 엔진의 장착 위치에 따른 기어박스의 다양한 개념 설계를 수행하였다. 또한 각 개념 설계에 따른 기어, 베어링 등의 요소부품 설계를 수행하여 시스템 구성에 따른 예상 중량을 비교 검토하였다.

Gearboxes for power transmission of a rotorcraft transfer power generated by an engine to the fan and the pusher for up, down and forward flight. The gearboxes are divided into the main gearbox and the sub-gearbox. The main goal of the gearbox design is to design the weight as light as possible within a range that satisfies all given requirements (transmission power, mounting space, etc.). In particular, the initial conceptual design is very important to reduce the weight of the gearbox, since the weight can vary greatly depending on the system configuration, even if it has the same function. In this study, various conceptual designs of the gearbox according to the installation position of the engine were presented. Also, the element parts such as gears and bearings in each concept design were designed by sizing for their life, and the estimated weights of the conceptual system configuration were compared.
