Description

Apparatus for generating momentum in a fluid environment.

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a rotary type device directly acting on a fluid for exerting momentum on flying means and vessels.

BACKGROUND OF THE INVENTION

At present, the momentum of flying means is generated by propeller, turboprop and jet propulsion. The propulsion rotors (helicopters) or the diversion of the thrust of the jet propulsion are used to generate vertical momentum. In addition, there are a number of experimental devices generating vertical momentum using various tipping axial propeller rotors or blowers. In vessels, the motive power consists of a number of differently adapted and profiled propellers, or, in the case of smaller fast vessels, the propulsive effect of a water jet.

SUMMARY OF THE INVENTION

Apparatus for exerting momentum in a fluid environment comprises an impeller whose blades curved upstream and fixedly attached to the " body " shaft of the " drives " form impeller channels enclosed by a housing. The essence of the invention is that the geometric parameters of the impeller, i.e. the input. and the outlet angles of the blades, the size of the inlet and outlet diameters are determined such that when rotating, there is a back pressure in the raceways, which together with the outlet pressure acts on the outlet surface ob. wheels to create momentum. The advantage of this device is its high performance with considerably smaller dimensions compared to current known means. When rotating, this device does not cause environmental rotation due to the reaction effect and friction, and thus the performance does not decrease. The main advantage of this device is that it utilizes the energy of the fluid by internal dynamics thereby minimizing the output kinetic energy.

DETAILED DESCRIPTION OF THE INVENTION

An exemplary embodiment of a device for generating a motive force in a fluid medium is shown in Figs.

An impeller 1, which consists of blades 2, a housing with a drive shaft 3 and a cover sheath 6, is illustrated. The inlet portion of the vane 2 forms an inlet angle A1 with the impeller plane and the outlet portion of the vane forms an outlet angle A2 with the impeller plane.

The figures show the flow of fluid ob. around 1. The function of this unit is as follows. When rotating, the fluid dc of the channels ob. of the relative velocity in the centripetal direction, that is to say against the action of the centrifugal force, thereby producing a counter-pressure, the magnitude of which is dependent on the magnitude of the inlet and outlet peripheral velocities and which, together with the outlet pressure, acts in the outlet portion. wheels on its surface, creating momentum.
