摘要
本文对某型机空调供气分配系统出现的问题进行了研究,通过运用流体仿真手段对供气分配系统的压力损失、温度、流量和流速进行计算分析,并与空调系统性能试验结果进行对比分析,选择合理的驾驶舱和客舱分配比例,最终确定了空气分配系统的改进方案,改进后的供气分配系统操作简单,维护方便,经试验测试性能满足空调系统设计要求。
We discussed the problem in the air-condition air feed-distribution system of X type aircraft. We calculated pressure loss,temperature,flux,and velocity of flow by using hydro-simulation. Then,we compared the air-condition capability test data with the simulation results. After the analysis,we chose the best distributing scales of cockpit and cabin,and finally determined the best improvement scheme of air feed-distribution system.The improved system is freindly to operation and maintenance,and can well meet the performance requirement.
