Abstract

The invention discloses a weighing and gravity center determining method for a wheel type rising and landing mini UAV, relates to weighing and gravity center determining technologies of the wheel typerising and landing mini UAV, and aims at solving the problem that the gravity center of a 100-200kg intermediate-scale UAV is hard to measure. The weight, the course-axis gravity center position andthe spanwise gravity center of the UAV are measured and calculated in the horizontal attitude, the UAV weight is recalculated and the vertical gravity center position is calculated by combining pitching attitude data with the horizontal attitude data, and the method is suitable for the wheel type rising and landing mini UAV whose launching weight is not greater than 200kg.

Description

technical field [0001] The invention relates to the technical field of weighing and center-of-gravity determination for wheeled take-off and landing small unmanned aerial vehicles, in particular to a weighing and center-of-gravity method for wheeled take-off and landing small unmanned aerial vehicles. Background technique [0002] In view of the fact that the flight control of wheeled take-off and landing small drones has high requirements on the accuracy of weight and center of gravity position, and the shortage of airport preparation warehouses or other open-air support equipment, as well as the actual situation of insufficient funds, a reasonable, simple and relatively accurate method must be adopted. Measure the weight and center of gravity of the drone. For traditional aircraft and large UAVs, custom-made weight center of gravity measurement equipment is generally used, and the UAV fixed structure and measurement sensors are integrated to achieve accurate measurement.
