飞机机动性随质量变化的换算问题研究

Research on the Conversion of Aircraft Maneuverability with Mass Change

文章以牛顿力学分析了质量反比律的适用范围和误差,给出了持续盘旋角速度峰值须满足的微分方程;提出并证明了用加速性计算单位重量剩余功率的定理,以及一种对比机动性的载油标准;针对几种机型的公开性能数据进行对比验证,证明了方法的正确性。

In this paper, the application range and error of the inverse mass law are analyzed by Newton mechanics, and the differential equation that the peak value of the sustained turning rate must satisfy is given. The theorem of calculating the specific excess power by acceleration is proposed and proved,and a fuel load standard for comparing the maneuverability is proposed. The public performance data of several types of aircrafts are compared and verified, and the results show the correctness of the method.
