low-speed airfoil 中文意思是什麼
low-speed airfoil
解釋
低速翼型-
This dissertation presents how to use the ultrasonic motor as an actuator to suppress the flutter of a two - dimensional airfoil section with a control surface. the ultrasonic motor, which features simple structure, high torque at low speed, small size, low weight and no electromagnetic contamination, is a promising actuator for the flutter suppression of small aircraft
超聲電機以其結構簡單緊湊、轉矩/質量比大、低速大扭矩、直接驅動,動態響應快、斷電自鎖和不產生磁場且不受外界磁場干擾等優點,有望成為一種非常有前途的作動器,用於小型飛機的機翼顫振主動抑制。 -
In order to accelerate the convergence speed, we employ the local time step, and implicit residual smoothing methods. finally, we use this method to get the steady solution of the flow around naca0012 and naca4412 airfoil at very low speed and some basic unsteady solution
本文對在低馬赫數下繞naca0012翼型和naca4412翼型的定常流場進行了求解,結果和實驗基本吻合,並對非定常運動情況進行了初步模擬研究,得出了一些有意義的結果。
