摘要
飞机地面压力加油系统通气能力计算是飞机燃油系统设计的重要环节。基于流体网络算法,给出了飞机地面压力加油系统和通气系统的计算模型,并对某型飞机地面压力加油控制失效时,油箱通气系统的通气能力进行了计算,获得了油箱承受的压力。通过计算结果与最大压力限制的比较,验证了地面加油通气系统的通气能力。模型对飞机地面压力加油通气系统的设计具有指导意义。
The vent system must keep the tank pressure within the permitted limits during ground pressure refueling. On the basis of flow network algorithm the calculation model for ground pressure refueling system and venting system has been established. According to the calculation of vent system when fuel overflow though the venting pipes in the course of ground refueling, the pressure in fuel tanks has been obtained. The comparison between the calculation results and the maximum pressure fuel tank could endurance, for verifying the vent system, has been taken at last. It indicate that the vent system satisfy the demands when ground refueling.
