| 摘 要： | 分析了飞行力学模拟与CFD模拟之间的影响关系。详细考虑了机动飞行过程中飞行参数变化与气动力变化之间的相互影响,开发出基于高精度CFD计算的飞行力学模拟方法。改进了传统飞行力学计算方法,保证了气动数据和飞行数据的计算精度。采用此方法,通过一次数值模拟即可得到飞行过程中气动力及飞行轨迹、飞行速度等的变化过程,可用于对飞行器设计方案进行精细模拟。

| Abstract: | The relationships between flight dynamics and CFD are analyzed, the interaction between flight parameters and aerodynamic loads is taken into account, then a new flight simulation method based on high precision CFD is developed, thus the accuracy of aerodynamic data and flight data are improved, and aerodynamic loads, flight path and flight velocity can be obtained through a numerical simulation. |
