      摘要:
      針對Gauss偽譜法在處理近空間可變翼飛行器最省燃油軌跡優化與可變小翼伸縮狀態的最優關系等問題時存在計算量大365英超体育投注、計算效率低下、優化精度低等缺陷,本文提出一種改進的多段整合優化的高斯偽譜法的求解策略?紤]到本文研究對象帶有可伸縮小翼的特殊性及飛行過程中聲速、密度、地球引力及發動機推力變化等因素的影響,對爬升模態進行合理分段365英超体育投注,建立多段優化模型,應用本文所提的改進方法進行了整體優化仿真試驗365英超体育投注。通過數值仿真得到整個爬升各子段的最少耗油爬升軌跡及小翼伸縮狀態。仿真結果表明:改進后的優化方法在計算時長365英超体育投注、優化精度等整體性能上得到了進一步的提升365英超体育投注。
