摘　　要：高原地区多发的危险气象往往会直接影响到飞机运行安全,为保障高原军用机场的飞机正常起飞,需要对高原危险气象下的机场端净空评定方法进行研究。首先,确定了高原条件下的飞机性能计算参数。其次,针对典型机型的爬升性能进行了区段参数位移计算和危险气象条件下的飞机性能分析,并对不同高度的正常爬升航迹和遭遇不同程度危险气象的爬升航迹进行了模拟仿真。最后,得到了典型机型在不同高度下的性能变化规律,以及危险航空气象干扰对飞机下沉位移量的影响。研究结果表明,高原危险气象情况下飞机在爬升飞行时面临下沉威胁,应对现有机场端净空障碍物限制面作出部分修改。Frequent dangerous weather in the plateau area often directly affects the safety of aircraft operation,in order to ensure the normal take-off of the aircraft at the plateau military airport,it was necessary to study the assessment method of airfield end clearance under the plateau dangerous weather.Firstly,the calculation parameters of aircraft performance under high altitude conditions were determined.Secondly,the calculation of the section parameter displacement and the aircraft performance analysis under dangerous weather conditions were carried out according to the climbing performance of typical aircraft types,and the normal climbing track at different heights and the climbing track suffered from different degrees of dangerous weather were simulated.Finally,the performance variation law of typical aircraft at different altitudes and the influence of dangerous aviation meteorological disturbance on aircraft subsidence displacement were obtained.The research results show that the aircraft faces the threat of sinking when climbing and flying under the high altitude dangerous weather conditions,and partial modifications should be made to the restricted surface of the existing airport end clearance obstacles.
