pitch thrust 中文意思是什麼
pitch thrust
解釋
俯仰推力-
Zero thrust pitch
無推力節距螺槳 -
This method makes it possible for investigating the unsteady nonlinear potential flow in a complicated environment with higher efficiency. the aerodynamic forces of a wing in couple motion of heave and pitch with ground effect are analyzed in detail based on the numerical result. it is shown that a thrust force exists when the wing is in heave motion
深入系統地分析了存在表面效應時機翼運動規律和氣動力之間的關系，研究結果表明，機翼升沉運動產生的推力與升沉速度幅值的平方成比例，推力和推進效率和振蕩頻率成反比；機翼的俯仰運動可以調節推力和推進效率，但是單純的俯仰運動不會產生推力。 -
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。
