以某型民用飞机再循环系统为研究对象,考察了从再循环系统到货舱和混合腔的流量分配。采用Flowmaster软件对再循环系统进行建模,对飞机在高空巡航和地面热天两种工况下的再循环系统流量分配进行了仿真计算。结果表明,该再循环系统的设计满足下游用户的流量需求。
Taking a type of civil aircraft recirculation system as the research object, the flow distribution from the recirculation system to the cargo hold and the mixing chamber was investigated. The Flowmaster software was used to model the recirculation system. The recirculation system flow distribution under high-altitude cruising and terrestrial hot-day conditions was simulated. The results show that the recirculation system is designed to meet the downstream users’ traffic requirements.
