DRIVE WITH CHANGING BLADES Russian patent published in 2018 - IPC B64C11/00 B63H1/00 

FIELD: aviation.

SUBSTANCE: drive contains a distribution body, a shaft with a gear for receiving rotation from a power take-off shaft and from an internal combustion engine. In the body on the axis, there are a central conical ring placed loosely with respect to the axis of which there is a distribution body with the blades, which can rotate increasing the manoeuvrability of the object. From the central wheel the movement is transferred via intermediate shafts and conical pairs to the shaft which is installed in the body by a bearing with a cardan and a sleeve rigidly mounted on it, and on the end of the shaft, there is a rigidly fixed shroud with openings perpendicular to the axis of the shaft rotation, there are axles installed in these holes, on which blades are installed rigidly, with the possibility of adjustment. Also, there is a disk rigidly mounted on the body with the possibility of adjustment, a cam is installed, and a lever with a roller is rigidly fixed on the blade axle, and the roller turns the axle and with blade at 90° and back when rolling on the cam and runs onto projections and recesses of the cam. Constant contact of the roller with the cam is provided by means of a spring.

EFFECT: drive efficiency enhancement.
