扭转角度 meaning in Chinese

angle of torsion

Lastly , previous vane are analysed by fluent , we calculate the pressure distribution chart and report chart of each wing form , then alter the torsion angle and the airfoil form of the vane respectively , finally ascertain the influence curve of the torsion angle and the airfoil form of the vane on which act the lift power
最后,通过fluent对设计出的叶片分析,得出其压力分布图和报告图。然后从改变叶片的扭转角度和翼型两个方面分析其对升力和阻力的影响。得出叶片的扭转角和翼型对升阻比的影响曲线,在文章的结尾部分估算了无人机的一些性能参数。
