In order to research the aerodynamic characteristics of grid fins effected by width to length ratio , the grid fins of three hight to width ratios were adapted in wind tunnel experiments at subsonic , transonic and supersonic speeds 為研究它對柵格翼氣動特性的影響規(guī)律,本研究采用風(fēng)洞實驗的方法對3種不同格寬翼弦比的柵格翼在亞、跨、超聲速3個馬赫數(shù)下進行了氣動特性的研究。
