SU58461A1 - Rotary paddle wheel - Google Patents

Description

The subject matter of the invention is a paddle wheel with a periodically varying value of the blade surface. For this, the blade is made of an elastic membrane tensioned on two parallel rods placed on two spokes of different lengths, and these rods with the spokes rotate simultaneously with equal angular velocities around the axes parallel to each other and the rods bearing the membrane .

In FIG. 1 shows a view of one blade of such a paddle wheel in the direction of the axes of rotation; FIG. 2 is a side view.

At the ends of two parallel axes G and G, rotating at the same speed in the same direction, the spokes B and B are of different lengths. Of these, the needle of greater length B is pushed forward a little relative to the needle B. Between the elongated rods In these spokes, in position (Fig. 2), an elastic membrane A is placed, connected to rods B, B. While the axes D and D are simultaneously rotated in the direction indicated in FIG. 1 arrows, rods B and B will be

take consecutive OO 1-1, 2-2 ... 7-7 and again OO positions, the distances between rods B and B will change, increasing to maximum, decreasing from the original size 0 -. In this case, the elastic membrane, stretching, will act as a crest of the blade and like a tallering wing.

In the manner indicated in FIG. 1 and 2 the vertical location of the centers of the axes of the G and G of the blade should inform the device horizontal movement. When the system is rotated 90 ° near one of the axes, the blade will already act in the direction of the vertical, i.e. it will inform the apparatus to move upwards.

The subject matter of the invention. A rotating propeller wheel with a periodically varying surface size of the blade, characterized in that the blade is made of an elastic membrane tensioned on two parallel rods B and B placed on two spokes of different lengths B and B rotating simultaneously with equal angular velocities around parallel axes G and G.
