摘　　要：本文以某型双转子民用涡扇发动机为例,根据AC-33.87-1A咨询通告以及国外试验实践经验,依托发动机性能计算软件GasTurb和多学科优化软件Isight,搭建了一套三红线状态自动匹配计算平台,采用多目标寻优算法,以多种不同的发动机调节手段作为变量,实现了在给定额定推力/功率和红线值条件下,快速匹配出满足最小改装量要求的调节手段组合,给出了试验构型改装方案。该三红线状态自动匹配计算平台大大提高了持久试验设计的工作效率,同时也为不同调节手段对三红线状态的进一步研究提供分析平台。Taking a certain type of dual-rotor civil turbofan engine as an example,according to the AC-33.87-1A advisory circular and foreign test practice experience,this paper uses the engine performance calculation software"GasTurb"and the multidisciplinary optimization software"Isight",and builds a set of triple-redline condition automatic matching calculation platform.Under the conditions of given rated thrust/power and triple-redline values,the platform adopts a multi-objective optimization algorithm and uses a variety of different engine adjustment methods as variables to quickly match the adjustment method combinations that meet the minimum modification requirements,which support the test configuration modification plan developpment.The triple-redline condition automatic matching technique greatly improves the work efficiency of engine endurance test design,and also provides an analysis platform for further research on triple-redline condition throught different adjustment methods.
