摘要
爬升速度是爬升阶段关键的可控节油点。首先分析爬升速度对爬升耗油的影响,然后建立爬升速度与爬升耗油的算例模型,通过波音的INFLT软件获得爬升相关数据,利用MATLAB实现插值计算得到其多项式函数关系,然后通过多次拟合函数的比较,确定爬升速度与爬升耗油量的拟合函数预测模型,最后对所得拟合函数进行验证并利用拟合函数获得最佳爬升速度。该方法的研究具有通用性,适合一般机型的航路爬升速度与耗油函数模型的研究。
The climbing speed is the key point of controllable oil-saving in the climbing stage. At first, the article analyzes how the climbing speed influences the climbing fuel consumption, then builds the calculation model between the climbing speed and the climbing fuel consumption, obtains relevant data of climbing from Boeing INFLT software and by MATLAB gets the polynomial function relation through the interpolar calculation. Next, through the comparison of several times fitting functions, the fitting function prediction model is confirmed. Finally, the fitting function prediction model is verified and the optimal climbing speed is obtained. The study method is versatile and suitable for the research on the climbing speed and fuel consumption function of the general types of aircraft.
