DEVICE FOR STUDYING AERODYNAMIC CHARACTERISTICS OF AIR FLOW WHEN USING MULTI-ROTOR UNMANNED AIRCRAFT VEHICLES Russian patent published in 2024 - IPC G01L5/13 G01M9/00 

FIELD: aerodynamics.

SUBSTANCE: invention relates to equipment for aerodynamic research, in particular to methods for studying the characteristics of the action of inductive air flows from the propellers of multi-rotor unmanned aerial vehicles (MR UAVs), including large-sized MR UAVs on suspended equipment and its characteristics. A device for studying the aerodynamic characteristics of air flows when using multi-rotor unmanned aerial vehicles, including a frame inside which is located a power unit having an electric motor, the shaft of which is coupled with a propeller. The frame has a modular design, consisting of sections formed by guides, interconnected bushings and fasteners with a threaded connection. The power plant located in the upper part of the frame comprises a crosspiece, the beams of which repeat the position of the beams of a multi-rotor unmanned aerial vehicle and have a movable carriage with the ability to move along the beam of the power plant crosspiece. The movable carriage comprises an element that fixes its position on the beam of the crosspiece, the movable carriage is associated with an engine, the shaft of which is connected to the screw, the ends of the power plant crosspiece are located in holders that limit the amplitude of movement of the crosspiece, and in the centre of the crosspiece there is a platform for mounting equipment. Instruments for studying the aerodynamic characteristics of inductive air flows and the characteristics of suspended equipment are installed on a frame with a mesh located inside the frame and connected to it with hooks.

EFFECT: modular, collapsible design of the device, through which air flows are formed, similar to the inductive air flows created by the MR UAV, but without using the device itself, and also having the ability to install measuring instruments at different heights.
