드론 공력성능 측정을 위한 실험 장치 구축

In the present study, we build an experimental testbed to measure the aerodynamic performance of a drone. The developed testbed is static, on which the drone is fixed. The testbed is used to measure thrust, battery amount, and drone flight angle using a load cell, a current sensor, and an IMU sensor. To demonstrate the procedure for evaluating the aerodynamic performance of the drone using the measured values, we performed preliminary experiments by directly installing the SYMA X8SW drone on the testbed. The measure values were used for understanding aerodynamic performance such as disc loading, figure of merit, and lift-to-drag ratio.
