surge margin meaning in Chinese
喘震边界
喘振边界
Examples
- The performance of modern internal combustion engine for locomotives often depend on the improvement of the supercharge performance . as part of the main component of the compressor , the inlet turning tube will affect the performance , especially the surge margin , of the compressor directly
现代内燃机车柴油机的功率和性能的提高在很大程度上取决于增压器性能的提高，压气机进气弯管作为增压器的组成部分之一，直接影响压气机的性能和喘振裕度。 - Simulation results show that the surge line moved up - left relative to the original one and surge margin became larger when wet compression is used , which means wet compression can extend steady - operation regions of compressors and the si a - 02 gas turbine . at last , based on the moore - greitzer model surge and rotating stall of a compression system with wet compression is modeled with consideration of inlet evaporative cooling and compressor pressure rise when wet compression is used
哈尔滨工程大学博士学位论文最后，本文在压缩系统moors grei上zer模型的基础上，考虑进口蒸发冷却的作用和压气机湿压缩过程的作用，推导出了湿压缩系统喘振和旋转失速的统一模型，该模型可以模拟系统发生喘振和旋转失速时的瞬态响应以及喷水湿压缩对系统瞬态响应的影响。 - To meet the needs for wider surge margin of the turbofan engine , a new model was developed to predict the characteristics of the fan / high pressure compressor and turbine in this thesis . several ways , including , variable inlet guide vanes of the fan , variable guide vanes of the high pressure compressor , the variable inlet area ratio of the mixer and the nozzle areas , were presented to enlarge the surge margin of the turbofan engine . meanwhile , a method of combined variable geometries for optimizing controls of inlet guide vanes of the fan , guide vanes and the first two stators of high pressure compressor , area ratio of mixer and noz zle areas was established
为了满足下一代作战飞机对推进系统的性能和稳定性要求，本文建立了压缩系统特性和涡轮特性的新模型，并分别采用改变涡扇发动机风扇进口导流叶片、压气机导流叶片和前两级静叶片、混合室进口处内、外涵面积比和尾喷管面积，研究了其对发动机性能和稳定性的影响，进而得出了涡扇发动机变几何扩稳的方法，为发动机变几何扩稳研究打下理论基础。
