依据Ｍｏｎｔｅｃａｒｌｏ法，对系统基本部件统计抽样，按故障树模型，确定系统平均失效时间，计算系统可靠度各项指标，进行可靠性设计。经２８００多条气动实验曲线测定表明，在控制精度、燃料消耗、系统可靠度等方面均达到国内高速风洞的先进水平。 According to the Montecarlo method, statistical sampling of the basic components of the system is carried out, and the average failure time of the system is determined according to the fault tree model, and the reliability of the system is calculated to carry out the reliability design. After more than 2800 aerodynamic test curves show that in the control accuracy, fuel consumption, system reliability, etc. have reached the advanced level of domestic high-speed wind tunnel.
