INTERNAL COMBUSTION ENGINE "NORMAS" OF N 24 DRONE Russian patent published in 2021 - IPC F02B41/02 F02B73/00 F01B21/02 

FIELD: engine building.

SUBSTANCE: invention relates to engine building. A two-stroke internal combustion engine (ICE) of a drone is proposed, the body of which is assembled from modules with a working stroke, with an early continued expansion of exhaust gases and from rotation synchronization modules, each element or link of which is mounted on the basis of seven location centers of a family of two types of contacting circles of the same diameter on coordinate grid, where the centers of six circles are located on the circumference of the uniting circle, coincide with the nodes of rotation of the ICE and the center of the volume of the combustion chamber of the cylinders. Some of the points of these centers are positioned as the vertices of an equilateral triangle or pentagon. In this case, three of them are the centers of the axes of rotation of the shafts with mounted cranks, which are located between the two cylindrical side cheeks. The axial centers of the shafts are the positions on which the gearing elements are fixed with the possibility of joint rotation, which include four ring-shaped gearwheels of the same geometrical dimensions, and nine cylindrical gearwheels and elements of chain drives. The diameter of the circle of the small seven circles is equal to the diameters of the pistons, cylinders, the circles of the cavities of the nine toothed gears of the engagement, the sprockets of the chain drives. A collapsible socket is provided in the area of the piston skirt, where the connecting rod is attached using ball joints. The cylinder head and the body of the two adjacent vortex antechambers are equipped with three sockets for installing the corresponding nozzles there. The air intake and gas exhaust elements of the internal combustion engine also include bellows bellows with protective casings built in parallel into the circuit. The working strokes of the pistons or the strokes of the same name in the cylinders are not performed at the same time, but alternate sequentially through 120°, respectively. The inner cavity of the bellows is connected to the cavity of the two-chamber bus.

EFFECT: invention ensures the maximum possible torque on the power take-off shaft.
