Experiment and Analysis of Lift Test for Coaxial Twin Rotor Unmanned Aerial Vehicle
Based on the structural characteristics and dynamic performance analysis results of coaxial twin rotor unmanned aerial vehicles,a lever platform with adjustable force arms was designed.Different forces of different sizes were applied to the force sensor using the lever principle,and the corresponding voltage was collected using a data acquisition card.The MATLAB curve fitting tool box was used to fit the curve relationship between lift and voltage,and the force sensor was calibrated to measure the lift of coaxial twin rotor unmanned aerial vehicles.The test results show that the fitting effect between voltage and lift is good,and the lift of unmanned aerial vehicles can be measured.This method has reference value for studying the lift testing of coaxial twin rotor unmanned aerial vehicles.
