The method of wing shape optimization of space shutlle has been developed with penalty function approach in which the objective function is the mass of the wing and the constraints are the hypersonic re - entry flight cross range , lift / drag ratio , and subsonic flight lift / drag ratio , the margin of the longitudial static stability and the magnitude of the horizontal landing speed etc 摘要介紹了在滿足高超音速再入橫向機動航程,高超音速再入飛行時的升阻比,亞音速進場飛行時的升阻比,縱向靜穩定性裕度和水平著陸速度等飛行性能設計要求下,用罰函數法尋求使航天飛機機翼質量為最小的外形優化方法并給出了算例。

Speed : a half - fiend has bat wings . unless the base creature has a better fly speed , the creature can fly at the base creature ' s base land speed ( average maneuverability ) 速度:半煉獄生物擁有蝠翼。除非其基礎生物有更好的飛行速度,半煉獄生物能以其基礎生物基本陸地速度的兩倍速度飛行(機動力良好) 。

He was alone when he set out last week on what was to be a three - hour flight , looking for a large flat area where he could try to set a new land speed record on the ground 他上個星期又一次單獨起飛,他當時的計劃是要飛行3個小時,尋找一片平地,沖擊最快著陸速度的世界記錄。

He vanished while scouting dry lake beds , looking for a place to set a world land speed record 他當時在偵察一處干涸的湖床,希望找到一處適合挑戰世界陸上極速紀錄的地方,之后便失去聯絡。

Whisper gnome base land speed is 30 feet , despite their size 基本陸地速度為30英尺,即使他們是小體型。

He set a new land speed record 他立下一項陸上速度新紀錄。
