    • PURPOSE: A flowing angle measuring device of supersonic waves is provided to measure accurate data when designing a rotary device by applying a principle of an airflow meter to supersonic waves. CONSTITUTION: A flowing angle measuring device of supersonic waves comprises a blade(100), a transfer unit(200), and a flowing angle measuring part(300). The blade follows a flow direction in a supersonic wave flow field. The transfer unit fixes one end part of the blade with a shaft, thereby transferring movement of the blade. The flowing angle measuring part measures the movement of the blade and converts the same into an angle. The blade is fixed to the shaft and is rotated. A cross sectional area of the blade in a direction where the blade moves based on the shaft is larger.
    • 目的:提供超声波流角测量装置,通过将气流计的原理应用于超声波来设计旋转装置时测量精确数据。 构成:超声波的流动角度测量装置包括叶片(100),转印单元(200)和流动角度测量部件(300)。 叶片在超声波流场中遵循流动方向。 转印单元用轴固定刀片的一个端部,从而转移刀片的运动。 流动角度测量部分测量叶片的运动并将其转换成一个角度。 刀片固定在轴上并旋转。 叶片在叶片基于轴移动的方向上的横截面面积较大。
