Abstract: An aerodynamic lifting-thrusting propulsion device has a frame with an axis, relative to which the frame is arranged with a possibility of rotation, a cardan joint having a cross, at least two aerodynamic surfaces, each of which is mounted on the cardan joint with a possibility of oscillations synchronously with a rotation of the frame, a rod mounted on the frame, the cardan joint being connected with the rod, the cross of the cardan joint having axes which are mutually perpendicular and located correspondingly in mutually perpendicular planes intersecting along an axis of the rod, one of the axes of the cross extending through an axis of rotation and an axis of the rod, the rod being arranged parallel to an axis of the frame, the axis of the frame being connected with each of the aerodynamic surfaces by a mechanical transmission providing a rotation of the aerodynamic surface synchronously and opposite to a rotation of the frame.

Abstract: An inventive wing (1) comprises an axis symmetrical plate, whose edges are embodied such that they are sharp. Said plate is provided with two rounded bosses arranged symmetrical with respect to the center thereof. Each boss is twisted with respect to the axis thereof. The plate can be provided with four rounded bosses symmetrically arranged with respect to the axis thereof. Said wing carries out motion and oscillations with respect to air when a lifting force and a horizontal power are provided. The aim of said invention is to increase aerodynamic performance.

Abstract: A method of producing a lifting force and a horizontal force by aerodynamic surfaces includes the steps of moving aerodynamic surfaces along a circumference and providing their oscillations; rotating each of the aerodynamic surfaces synchronously with the movement along the circumference, in a direction which is opposite to it, relative to an axis of rotation which is parallel to an axis of the movement along the circumference, with an angular speed which is equal to an angular speed of the movement along the circumference, and performing oscillations of each of the aerodynamic surfaces synchronously with a rotation relative to mutually perpendicular axes located correspondingly in two mutually perpendicular planes which intersect along an axis of rotation of the aerodynamic surfaces, wherein one of them passes through an axis of the movement along the circumference and the axis of rotation.

Abstract: A method of obtaining mechanical energy from a turbine includes supplying a working medium into channels of a rotor of a turbine, accelerating the working medium while flowing out from the channels in one direction along a circumference and normally to a radius of a rotor so as to make the rotor rotate, supplying the working fluid from the rotor channels into a space created within a casing above the rotor where it interacts by friction with the casing while flowing out through openings of the casing so as to accelerate in one direction and to make the casing rotate, forming the space in the casing closed and extending along a radius of the circumference along outlet openings of the rotor channels, and accelerating the working fluid flowing out through the openings of the casing along a circumference and normally to a radius of the casing in a direction opposite to a direction of flowing out from the rotor.
