飞机航路爬升与下降性能计算模型研究

Research on Models for Calculating Climb and Descent Performance of Aircraft

文章主要分析了航路爬升、下降性能计算的一般方法,包括油耗、空中距离及所耗费的时间的计算。借助某航空公司的性能手册,得到多组飞机在不同重量、不同大气条件下爬升到不同高度(从不同高度下降)的油耗、空中距离、时间数据。再运用线性回归(拟合)的办法得到飞机在不同条件下的爬升、下降油耗等数值的计算公式。公式能够通过相关统计检验,并且在与性能手册数据比较中发现该计算公式的误差较小,可以接受,证明该公式可行。

The thesis analyzes general calculation method of enroute climb （descent） performance, including fuel consumption, nautical air miles and time elapsed. By using the company＇s performance manuals we can get fuel consumption, nautical air miles and time under different conditions such as weight, atmosphere and height. Then we use Linear regression（fitting） to get the formula to calculate climb and decent performance data such as fuel consumption. The result of regression is statistically tested. And comparing with the result calculated by software, the error is acceptable, which proves that the method is feasible.
