摘　　要：针对某超声速风洞试验运行中面临的主调压阀位移传感器故障导致阀门失控、试验段正激波回退以及不同马赫数的总压超压保护功能不足等安全隐患,提出了主调压阀智能判定规则及处理措施,研制了正激波位置实时监测系统,完善了总压保护值全域匹配等安全控制策略。实验结果表明:上述优化措施运行稳定、可靠,提高了控制系统智能化和自动化水平,对保障风洞试验安全运行有重要作用。To solve the problems in the certain type supersonic wind tunnel test about the runaway valve causing by the main pressure valve displacement sensor fault,the normal shock wave return to test-section and total-pressure excessive pressure protection insufficiency for different mach numbers.This paper presents the intelligence decision rule and treatment measure of the main pressure valve,researches the real-time monitoring system for normal shock wave position and improves the universe matching of total-pressure excessive pressure protection.The test results show that the above optimizing measures run stably and reliable,raise the intelligent and automatic level of control system,and play an important role for ensuring the wind tunnel test security.
