重心位置对飞机性能的影响分析

Analysis of Effect of Gravity Center Position on Aircraft Performance

在不引进新飞机、不加装新设备且同样运行条件下,航空公司可以通过调节飞机重心位置来使得飞机搭载更多的旅客或货物,提高飞机载重量。文章分析了飞机重心对于飞机气动性及性能的影响,运用波音的性能软件BCOP,以思茅机场的运行条件为例,计算不同重心位置对飞机性能和运行条件的影响,验证了配载重心位置可以提高飞机运载能力的可行性,为航空公司实际运行提供了参考数据和材料。

The adjustment of gravity center position enables aircrafts to carry more passengers or cargo under the same operating conditions without importing new aircraft or installing new equipment.This paper analyzes,based on the operating conditions at Simao Airport,the influence of aircraft gravity center on aircraft aerodynamics and performance.Boeing's performance software BCOP is applied to calculating the influence of different gravity center positions on aircraft performance and operating conditions.It is verified that positioning gravity center can improve the loading capacity of aircraft,which provides reference data and resources for the actual operation of airline companies.
