摘要
为了充分利用机场跑道富余长度,提高国产民机商载能力,在满足民航适航和运行规章要求的前提下,就起飞重量、起飞速度比与平衡起飞决断速度对起飞距离的影响分别进行了单参数敏感性分析。通过仿真计算建立了实施组合参数敏感性分析的ARJ21-700飞机网格工具图,并进一步建立了不平衡起飞场长限重增量速查表,最后结合ARJ21-700飞机的实际运行环境对典型高原机场进行实例分析,比较了不同可用距离差异下使用不平衡起飞方法对场长限重和起飞速度比的影响。结果表明:实施不平衡起飞能够在满足规章要求的前提下有效利用跑道富余长度,增加商载能力,提升航空公司经济效益。
In order to make full use of the surplus length of the airport runway and improve the commercial carrying capacity of domestic civil aircrafts, this article separately discusses the effects of take-off weight, take-off speed ratio and balance take-off decision speed on take-off distance under the premise of meeting the requirements of civil aviation airworthiness and operation regulations. The grid tool diagram of ARJ21-700 aircraft for implementing combined parameter sensitivity analysis is established through simulation calculation, and a quick reference table for unbalanced take-off field length limit weight increments is further established. Finally, an example analysis is carried out on a typical plateau airport based on the actual operating environment of the ARJ21-700 aircraft, and the impacts of using the unbalanced take-off method on the field length limit weight and take-off speed ratio under different available distances differences are compared. The results show that the implementation of unbalanced takeoff can effectively utilize the surplus runway length to increase the commercial load capacity and improve the economic benefits of airline under the premise of meeting the requirements of regulations.
