METHOD FOR COOLING UNMANNED AERIAL VEHICLE AND DEVICE FOR IMPLEMENTING METHOD Russian patent published in 2021 - IPC B64D13/00 B60H1/26 

FIELD: aviation.

SUBSTANCE: cooling device for the unmanned aerial vehicle consists of a body with four symmetrical hollow-structured beams, each of which has electric motors connected to propellers that create an air flow. Each pair of propellers is positioned diagonally. The case contains the upper and lower parts, which form the inner space of the case, inside which there is a printed circuit board with elements of radio electronic systems, and a ventilation grill is located in the lower part. The airspace is formed by the hollow beam structure and the interior of the enclosure. An airfoil assembly is used that is located between the inlet and outlet side of the air stream and has a hollow structure and an outlet slot located on the outlet side of the air stream. Each beam has an airfoil and landing gear assembly whose zero lift line matches the direction of the airflow from the rotating propellers. Each airfoil and landing gear assembly has an exhaust slot extending from its internal airspace. The top side in each pair of chassis function airfoils has the same orientation, and the top sides of the airfoil at adjacent chassis airfoil units have a different orientation. The upper side of the airfoil and landing gear unit, located on the left front beam, is located on the right. The method is characterized by the use of a device.

EFFECT: group of inventions is aimed at improving the reliability of cooling.
