| 摘 要： | 为了使现有轻型航空发动机在海拔高度为10km的高空保持原有动力性不变,需要采用二级涡轮增压,保持发动机在不同海拔高度时稳压腔内的进气密度与海平面的一致.对原发动机在一级涡轮增压的基础上进行二级涡轮增压匹配.这里采用AVL-Boost软件建模,根据实验校验一级涡轮增压模型,然后建立二级涡轮增压模型.考虑小型离心式压气机高...

| Abstract: | In order to operate the light aero-engine without power loss at altitude 10 km,two-stage turbocharging was required to keep the intake air density at in plenum different altitudes the same as that at sea level.AVL-Boost model was built to simulate the working process of single-stage turbocharging engine and the model was verified through relevant experiments.Based on the primary model,the two-stage turbocharging model was built.Considering the effect of Reynolds number on small size centrifugal compressor a... |
