摘　　要：以仿真分析和试验试飞为手段,对某型客机空气分配进行优化设计。首先建立飞机座舱热载荷动态仿真模型,分析飞机驾驶舱及客舱新的供气需求;其次根据飞机空气分配管路实际构型建立Flowmaster仿真模型,并基于模型调节管路构型,以调整各舱室空气分配流量,实现驾驶舱和客舱的流量需求;最后将优化设计应用于民用飞机空气分配系统中,仿真分析和试验试飞验证结果吻合较好,说明了仿真技术手段的合理性。In this paper, simulation analysis and experimental validation are applied for indicating air distribution configuration complied with the requirements. Firstly, the cabin/cockpit heat load dynamic model is set up and air supply requirement is analyzed. Secondly, to fulfill the target of air supply, Flowmaster model for one civil aircraft air distribution system is built and quantity of supplied air is adjusted based on the model. Lastly, ground/flight test is performed to validate simulation result similar with test result, and the air supplied to the cabin and cockpit meets the requirement of air worthiness standard and high level requirement. This attempt is the trial of civil aircraft air conditioning system distribution development and research, and the methods adopted are effectively enhancing the civil aircraft independent research capability.
