The centralized filling subsystem is used for hydraulic ground service, in which the hand pump is the power component to complete the conversion of mechanical energy to hydraulic energy generated by manpower, thus realizing the purpose of injecting hydraulic fluid from the ground hydraulic fluid tank to the aircraft hydraulic reservoirs. In this paper, from the investigation of domestic and foreign typical civil aircraft filling maintenance method and hand pump data, comprehensive consideration and balance of its displacement, weight, installation size, operation force and mechanical efficiency and other key technical indicators, put forward a reasonable displacement and parking space, light weight, pretty mechanical efficiency of hand pump design scheme. It can greatly improve the efficiency of ground filling, reduce the burden of ground maintenance and save costs.
