transonic drag
解釋
跨音速阻力-
In this paper based on the optimization design method using control theory for airfoils, a design method for multi - element airfoils is developed with the chimera grids. and optimization computation for reducing drag of shockwave of single airfoil in transonic flow is also successful
本文的主要工作是：以在控制理論進行單段翼型優化設計的基礎上，利用嵌套網格技術將其發展為適用於帶襟翼多段翼型的優化設計。 -
The flowfield over low - drag and long - range projectile with small attack angle is numerically studied from transonic to supersonic velocity. it provides basic work for aerodynamics characteristic of this projectile and for lateral jet interaction flowfield, and it shows this projectile can decrease drag. zonal method is tried to compute flow over projectiles and results is satisfied, but computation is much slower
系統研究了低阻遠程彈丸在小攻角狀態，低跨聲速、高跨聲速和超聲速時的非對稱繞流流場，為該彈形氣動力研究提供理論指導並為彈丸側噴流研究奠定基礎，結果顯示低阻遠程彈丸外形具有優化繞流場、減小空氣阻力的特點。
