| Abstract: | An important design indicator of aircraft hydraulic system is to meet the load flow demand in full flight profile scenes. This paper introduces a digital simulation analysis method of load flow demand for aircraft hydraulic system. According to the actual structure of the hydraulic system, mathematical models are developed to build the load subsystem model of the hydraulic energy subsystem and the hydraulic users. And then the simulation analysis of the load flow requirements of hydraulic system was carried out under typical flight profiles. The dynamic process of the aircraft hydraulic system is simulated, which can reflect the coupling dynamic characteristics between the aircraft hydraulic system and the hydraulic user load.The simulation results show that the hydraulic system model meets the requirements of hydraulic system analysis and can be used for hydraulic system design support. |
