  1. The relationship between the load measured by strain method and the load calculated according to flight parameters and the wind tunnel test data has been investigated in this thesis. the result showed that the calculation load based on the flight parameters and wind tunnel test data is acceptable in subsonic speed and gets good agreement, with the load measured by strain method

    本文研究了採用應變法實測載荷和根據飛行實測參數和風洞實驗數據計算載荷之間的關系，研究表明採用飛行實測參數和風洞實驗的數據計算載荷在亞音速范圍內是可行的，與採用應變法實測載荷是吻合的。
  2. 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律，本研究採用風洞實驗的方法對3種不同格寬翼弦比的柵格翼在亞、跨、超聲速3個馬赫數下進行了氣動特性的研究。
