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。< uk > the configuration has two tractor propellers, full - span double slotted flaps deflected 45, and a high tail. < / uk >
< uk >實驗模型有二兩拉力螺旋槳，全翼展雙縫襟翼偏轉45 ，並有高置的水平尾翼。 < / uk >The configuration has two tractor propellers, full-span double slotted flaps deflected 45°, and a high tail.
實驗模型有二兩拉力螺旋槳，全翼展雙縫襟翼偏轉45，並有高置的水平尾翼。The results of research show that the rotor thrust increase 4 % and the download force on the wing can be as large as 10 percent of the total rotor thrust
研究結果表明：旋翼的拉力大約增加4 ，旋翼的下洗載荷相當于整個旋翼拉力的10左右。In order to understand the rotor / wing interaction each other, firstly, the change of the isolate rotor thrust with the collective pitch and rotate speed is tested, secondly, the change of the rotor thrust with the collective pitch, rotate speed and the wing / rotor distance is scaled, when the wing is placed underside the rotor, lastly, the pressure on the wing due to the rotor wake is scaled
為了搞清楚它們之間的相互影響，本文首先測量孤立旋翼的拉力隨總距和轉速的變化；再測量有機翼時旋翼的拉力隨總距及轉速的變化以及隨旋翼機翼間的距離變化；最後測量旋翼尾流對機翼表面壓力的影響。分享友人
