DEVICE FOR MEASURING THRUST OF DUCTED FAN-TYPE REDUCED-SIZE ROTOR AND THRUST CALCULATION METHOD USING SAME

摘要

The present invention relates to a thrust measuring device capable of measuring loads in three axial directions which are component forces of total load generated in a ducted fan-type reduced-size rotor and the duct load, in the z-axis direction, which is a component force of the load due to a duct, and relates to a thrust calculation method for calculating total thrust, thrust by the duct, and thrust by a fan by using the same. The thrust measuring device of the present invention includes: a drive shaft rotated by a drive motor; a rotating part having a hub rotated about a rotating shaft (z axis) by the drive shaft and a fan radially coupled to an outer peripheral surface of the hub; a duct positioned on an outer peripheral side of the fan; a load part to which a total load generated by the rotation of the rotating part is transmitted; a three-axis load measuring part having at least a portion coupled to the load part to measure loads in first axis (x axis), second axis (y axis), and rotating axis (z axis) directions, which are component forces of the total load; and a duct load measuring unit supporting the duct to measure a load in the rotating axis (z axis) which is a component force of the load due to the duct in the total load, wherein the first axis (x axis), the second axis (y axis), and the rotating axis (z axis) are perpendicular to each other.;COPYRIGHT KIPO 2018
