Wind Turbine

Winflex Description

Dr. Vladimir Kliatzkin, a scientist with more than 40 years of experience in energy production and accumulation systems for aviation, internal combustion engines  and hybrid systems, originally developed the innovative wind-power technology and is currently commercializing various applications incorporating the technology through WinFlex.

WinFlex, a company based in Israel, received one of the most coveted prizes in the GE Ecomagination Challenge for developing a wind turbine system that uses a light, flexible cloth sheets made out of composite materials as the rotor system for a wind turbine. The WinFlex rotor is an inflated, cylindrical wheel tied to a central hub by spoke-like blades linked to a hub in the center of the wheel. The whole system is structurally similar to a bicycle tire.

Euler 1

A project based on the development of internal composite structure that permits orient axes of

strengthens filament in load vector instruction and supported from buckling in separate points

only. Distance between supporting points must be less of critical length, - from buckling

point of view (critical length in Oiler determination). That 3D filament structure permits

decrease weight of strengthens material and method installation – weight of the matrix. But

main preference is increasing of this structure, increasing of moment inert ions and resistance

of cross section without any problems have placed in the 2D composite structure. Composite

that permits creates base architecture elements -walls, ceiling, floor, etc. Building from this

material, don't need an additional strengthens the social system, and may be realized to

1400m height (from specific strength aspect). Building from ready parts may be very safety

in seismic dangerous territory. Samples of this material are projected (include FEM) and

tested at the Institute of Materials Laboratory at the Polytechnic Institute, (Technion) in

Haifa. Illustration of weight/intensity ratio has been compared to pressure, bending and shear

between this composite and alumni sandwich structure at MIL-STD-4018.Testing results

illustrate from 2 to 8 preference of presenting structured 3D composite. In increase, proposed

composite achieved Thermal conductivity 0.025 W/ (m2* K) compare with concrete

possessing 13W/(m2*K). Surface quality achieves polish material and don't cry for extra

discussion. Outer and internal surface have surface grade like polish glass. Material surface

may be coloured (in any color), with no need plastering or complex painting and can be

planed during the planning stage. End production process results a coloured material, surface

quality close to polish glass, with high resistance against erosion and UV, very low weight,

very high strength, and with significantly decrease of energy consumption needs whether for

heating or chilling. During the material production, in the process procedures, needs for

internal infrastructure such as communication, plumbing, electrical and other can be

incorporated. Building assembly may be executed with 2 floors daily. Price of a product,

fabricated and installed varies between 5 to 20 USD/m2. In comparing with conventional

method this is few times lower. Samples Material, tested, illustrated in fig 1.
