| 摘 要： | 根据风切变对飞机飞行影响的机理,以及FAA对CATⅠ类着陆最坏条件下的边界要求,推导了风切变的危险程度判据。通过计算,分析了垂直风切变与水平风切变对飞行性能的影响的异同,并通过对危险判据与性能恶化参数的相关性研究,提出了适用于机载风切变探测告警系统的告警准则。

| Abstract: | A simplified windshear hazard criterion is developed in this paper, based on the mechanism of the effects of windshear on aircraft flight and the CAT I worst landing limits specified by FAA. The effects of longitudinal and vertical windshear components on the flight performance are analysed respectively, in the purpose of investigating the hazard of winds-hear components. After careful study of the correlationship between the hazard criterion and the performance deteriorating parameter .72. the alert principle and threshold of the predictive airborne windshear detecting and warning system are discussed in detail in this paper. |
