摘　　要：针对某型飞机在飞行试验中并联多发气源引气流量不平衡导致的压力干扰问题,基于多源并联管网流量分配原理开展分析,找出根本原因,提出气源系统设计方案,并使用AMESim和CFD进行仿真验证。结果表明:经设计改进后,多发气源系统引气流量差异控制在10%以内。This paper aims at the problem of imbalance flow in bleeding air system of a type of aircraft found in flight test,performs root cause analysis basing on the flow distribution principle of multi-source parallel pipeline network,provides bleed air system design proposal according to root reason,and verifies the design using AMESim and CFD software.The results show that the flow difference between the multi-source parallel pipeline bleed air systems can be controlled within 10%.
