  1. Finally, the experiments on the rotor bvi noise are conducted both in an aeroacoustic laboratory and at outdoors, and the noise characteristics at different locations are measured on different blade - tip mach numbers, collective pitch angles and rotor configurations. based on the experimental results, some new conclusions are presented

    本文第七章分別在「消聲室」和外場進行了模型旋翼的槳-渦干擾噪聲實驗，對不同馬赫數、不同槳距角以及不同旋翼布置情況下的不同測點進行了噪聲測量，得出了一些新的結論。
  2. The main technological characteristics include not only the integrated optimizing design of variable speed and constant frequency, ensuring the wind turbines to adapt to diversified wind plants with different temperatures and geographical conditions, but also the maximum wind power captured at optimized tip speed ratio below the rated wind speed and security protection of constant power output above the rated wind speed by variable pitch regulation
