  1. The complicated aerodynamics characteristic of spinning projectile with lateral jets and with attack angle is studied detailedly. the formation and changes are analyzed including magnus force, normal force, yawing moment, pitching moment and pressure center

    系統分析了旋轉側噴彈丸復雜的空氣動力學特性，分析了馬格努斯力系數、法向力系數、偏航力矩系數、俯仰力矩系數和壓力中心等參數的產生機理和變化規律。
  2. All models can predict the attached and little separation flows. for the high angle - of - attack separated flows with distinct history effects, the j - k and k - g models perform better than b - l model. for multi - body and multi - block mesh system, model k - g, which does not need the distance normal - to - wall, performs much better adaptability for complex geometries

    所有模型都可以很好地模擬附體及和小分離流動;對于具有明顯上游歷程效應的大迎角分離流動， j一k和k - s模型的模擬能力較強;對于多體干擾和多塊網格系統， k - s模型無需計算網格單元至物面的垂直距離，具有較強的適應能力，且計算效果最佳。
