空气涡流场中飞行物体轨迹参数计算方法的探讨
Approach to Trace Calculation Method for Flying Object in Eddy Air Flow Field
【摘要】 对涡核扰动源引起的无限空间和有限圆形空间内的空气涡流流场进行了理论分析和数学描述,建立了流场的速度沿径向的分布关系式,引用旋转坐标系的方法解决了空气涡流流场影响环境中飞行物轨迹参数的计算问题。
【Abstract】 :In this paper ,theoretical analysis and mathematical d escription to edd y flow aroused by eddy core disturbance in free space and limited cylinder space are conducted, speed distribution formula along radial direction about rotating eddy air flow field is established, then, by means of rotating coordinate syste m, trace calculation problem of flying object against rotating air flow field r esistance is solved.
