一种用于飞机起飞性能计算的数值仿真模型

A mathematical model used to calculate the takeoff performance for an aircraft

针对飞机起飞性能计算公式过于简单化的问题 ,提出了一种全量数值仿真模型。该模型包含了起落架系统特性和全机气动力特性 ,根据飞机总体设计参数可仿真给出其起飞性能指标。以某型飞机为例进行了计算 ,结果表明 。

Different from the simplification of the expressions used to calculate the performance of takeoff in the past, a mathematical model including the characteristics of airplane undercarriage system is introduced in this paper. On the basis of the vehicle oriented parameters and the aerodynamic characteristics, the history of takeoff is emulated. Simulation studies show that the model is useful in the aircraft design.
