    Abstract: 本文之目的在發展一個數值分析的方法來 計算直昇機螺旋槳旋轉時所產生的升力及阻力 。本方法組合邊界層法及勢流法兩種數值方法 所構成,作者使用本文之方法計算九種不同外 形螺旋槳在盤旋時的流場(次音速及穿音速) , 所得結果與實驗收據比較誤差相當小,顯示本 文所提方法能夠準確的計算出螺旋槳旋轉時螺 旋槳葉片周圍的流場。
    A three-dimensional viscous-inviscid interaction analysis has been developed to predict the performance of rotors in hover at subsonic and transonic tip speeds. The analysis solves the full-potential and boundary-layer equations by finite difference numerical procedures. Calculations were made for several different model rotor configurations in hover at subsonic and transonic tip speeds. The results were compared with predictions from a two-dimensional integral method and with experimental data. The comparisons show good agreement between predictions and test data.
