The invention relates to renewable energy and can be used to create new non-rotating converters kinetic energy for wind and hydro, based in free air or water flows.

Known swivel arm of wind and hydro rigs with oscillating vertical blades (1), containing kinematically interconnected double main and auxiliary blades. However, this design performs in extreme left and right positions of the main blades torque moments with substantial losses, especially at low angles of attack to the incident flow.

An object of the invention is the creation of more effective non-rotating technical means of converting kinetic energy of air or water flows with a more uniform torque on the shaft of the multi-pole generator, and the improvement of spontaneous start the console after it is stopped during a storm or scheduled maintenance.

This object is achieved in that at the ends of the upper and lower sections of the main blades from the side of the incoming flow is additionally placed at the ends of the pins pivoting the flaps streamlined shape held within the bounding corners sprung forks and return�and springs with adjustable tension.

The plane of pivoting of the flaps as the main and auxiliary blades, have a simple symmetrical streamlined shape that reduces overall cost and improves manufacturability.

The invention is illustrated by schematic images where:

Fig.1 is a top view of the operating positions of the planes of the blades and flaps in air or water streams.

Fig.2 is a side view of a main blade with dual flaps.

a) side view; b) top view.

Console 1 contains kinematically associated 2 main and 3 auxiliary dual blades, placed in a sealed casing 4. At the ends of each of the main sections of the blade 1 is further placed on both ends of the pins 5 swing the flap 6, on which are fixed two resilient plug 7 with damping pads 8 and the rack 9 connected by means of the return spring 10 with the threaded shaft 11 associated with curly nut 12 with angled bracket 13 fixed on the carrier plate 14.

Inside each of the hollow sections of the main blade 2 is placed reinforcing their strength corrugated fin W�strasti 15, especially in places of contact with the damping pads 8 spring forks 7.

The console works as follows.

If, for example, initially the axis of the console 1 was in the middle position coinciding with the direction of flow, and the plane of the main lobe in the left, they, together with the auxiliary blade 3 will move to the left (Fig.1). With continued movement of the blade 2 to the leftmost position, the angle of attack to its plane relative to the flow is decreased and in the conditional area " a " W'(in the vertical plane m-m') it will be equal to zero. At the same time the auxiliary blade 3 under the continued pressure on its plane of the incoming tide will continue to turn the console 1 to the left, with the blade 2, going into negative angle αl-will begin to turn around its axis in the opposite direction, and the flap 6 - additional pivot at a fixed angle of αW-and will create an additional force is required to pivot the working of the blade 2 at full angle βl-and simultaneous with the reversal of the auxiliary blade 3 is at a greater angle (a new relative position of the two blades is shown by a dotted line). Thus, in the range A3- W'creates the maximum force to rotate the console 1 to the right. All subsequent processes on the right side in �the range And 1'-A1will be identical. Full-time rotation angle of console, 1 in each direction is αK+K-and in practice, is in the range of 50-70 degrees.

Required operating tension of the return spring 10 at a constant shoulder t the rack lever 9 is effected by turning the adjusting nut figure 12.
