ROBOTIC METHOD FOR RESOURCE TESTS OF UNMANNED AERIAL VEHICLES OF VERTICAL TAKEOFF AND LANDING Russian patent published in 2022 - IPC B64F5/60 G01M7/02 G01D21/00 

FIELD: aviation.

SUBSTANCE: invention relates to the field of strength tests of full-scale structures for determination of a resource of unmanned aerial vehicles of vertical takeoff and landing, simulators, and their elements. Load cells and vibration-measuring converters on elements of an object structure are mounted on an object of tests, same as in flight tests. Using an adapter, the object of tests is fixed to a movable flange of an industrial robot, simulating free flight conditions. Movements of the flange of the robot with different levels of amplitudes and frequencies are alternately reproduced, movements of the flange of the robot and readings of sensors are simultaneously measured. Correlations are established between movements of the flange of the robot and readings, rules of vibrational movements of the flange of the robot, causing damages to the object of tests, equivalent to damages in a typical flight, are formed. Formed rules of vibrational angular and linear movements of the flange of the robot are reproduced with simultaneous measurement of readings of sensors until required development is achieved.

EFFECT: reduction in labor intensity and duration of tests, increase in the reliability of tests due to reproduction of a random range of a vibrational load in a typical flight by amplitude, by frequency, and phase.
