    此外，滑流的旋轉和尾翼處下洗的變化也是重要的因素。
  2. The potential flow theory is then applied to the overlap of the slipstream and the flow over the wing

    用位流理論來處理螺旋槳滑流與機翼繞流的迭加。
  3. The paper analyzes the characteristic of aerodynamics with structure of helicopter propeller blade, dissertrates vortex theory and the theory about gliding air field which produce the power of helicopter propeller blade. at the same time it also deduce the method of computing the induced velocity produced by helicopter propeller blade with vortex theory. at last, an influcence to the spreading of sound is discussed

    並且將兩種定位演算法進行了比較，說明了優劣；結合直升機的結構分析了旋翼的空氣動力特性，論述了直升機旋翼產生拉力的滑流理論和渦流理論，結合渦流理論論述了直升機旋翼流場誘導速度的計算方法，在此基礎上分析了直升機旋翼流場對聲音傳播的影響。
  4. Based on the mechanism of slipstream interaction, described in this thesis is firstly the interaction of the propeller slipstream with the wing 、 fuselage and horizontal tail. subsequently, the changes in lift 、 drag and pitching moment are derived, giving an engineering model for the prediction of the increments in the aerodynamic characteristics caused by the interference between the propeller slipstream and the other parts of aircraft. this method offers a powerful means to the calculation of the aerodynamic interaction between the propeller and the aircraft, providing reliable data for the design of and aerodynamic calculation on propeller - powered aircraft

    本文以滑流干擾的機理為出發點，研究了螺旋槳滑流與飛機機翼、機身、平尾組合體之間的相互影響，推導出滑流引起的飛機升力、阻力和俯仰力矩的變化，給出了滑流干擾對機體氣動特性影響的工程估算方法，為研究螺旋槳與飛機部件之間的相互干擾提供了有力的工具，為以螺旋槳發動機為動力的飛機的設計和氣動計算提供可靠的依據。
  5. The effects of the slipstream boundary are solved by the slipstream boundary condition met using the so - called vortex image method. based on these considerations, the change in the circulation around the wing is obtained, and the velocities induced by the original vortices and the imaged vortices at the wing are subsequently derived. the present research also gives an analytical expression of the drag change due to the slipstream interference

    對于滑流邊界的影響，用「鏡像法」來使滑流邊界條件得到滿足，導出了由於滑流影響機翼環量的改變，求得渦及其鏡像在機翼處的誘導，並首次導出了螺旋槳滑流對機翼阻力特性的影響的解析表達式。
