Abstract:The hybrid actuating system with HA/EHA dissimilar redundancy configuration is the development trend of the future multielectric aircraft actuating system. In order to solve the problem of high energy consumption and serious overheat in the hybrid actuating system, first, the efficiency analysis of HA and EHA that constitute hybrid actuation system should be made, by comparing the efficiency characteristics, an optimization method is proposed to automatically switch to a high efficiency channel according to different working conditions; Then, the operating characteristics of air flight load of four quadrant are analyzed, to load F and actuator velocity conditions constitute the V network as a starting point, proposes a hybrid energy recovery and adaptive conditions of actuator system work mode. Compared with the traditional working mode, the energy consumption is reduced by more than 50%. The effectiveness of the method can be verified by simulation.
