Blades for a wind turbine.
Fundamentally new blades for a wind turbine. The basis of each blade – half of the reuleaux triangle, which is bent as desired. The new shape of the blade is a valuable side effect: side wind flow no longer goes sideways, even now they turn the screw. This wind-head screws from the air feel the wind speed of one meter per second, which is two to three times less than that of conventional blades.
Description:
A fundamentally new propellers – blade for a wind turbine. It is not the three blades with the thickening and contraction of streamlining, both in the classical windmill, and the cone of the blades. The basis of each blade – half of the reuleaux triangle, which is bent as desired.
The new shape of the blade is a valuable side effect: side wind flow no longer goes sideways, even now they turn the screw. This wind-head screws from the air feel the wind speed of one meter per second, which is two to three times less than that of conventional blades.
Advantages:
– blades for wind turbine feel the wind speed of one meter per second, which is two to three times less than conventional blades
– the propeller allows to improve aerodynamic characteristics of the wind turbine by creating the body feathers of the blades of the laminar flows, without disrupting the flow of the feathers of the blades, pivot the front edge of the following blade after the previous execution of the surfaces of each of the feathers blades in a single plane, use the surfaces of the feathers of the blades in parallel planes, the use of bi-directional air flow, perceived elements of the pen blades, the flow from one propeller blade to the other blade of the screw,
– increased aerodynamic efficiency of the propeller due to more complete use of energy of the air flow acting on the feather blades, more prolonged use of blades of the propeller when air flows with low and high energy capture air flow in different directions, the distribution of forces on the propeller blades in case of the air cone, implementing the use of wind flows with different energy,
– advanced technological capabilities as a result of simplification of the design of the screw, as all the elements, including feathers and inboard portion made of a sheet material, a common butt, simplify structures to fulfil, without special profiling operations on the feathers of the blades, increasing the possibilities of use in various fields, for example in wind energy and propellers, the screws in different applications, the presence of the screw of the combination of blades of different forms, increasing the range of screws with the use of sheet materials of different thickness, increasing the range of screws to their use of different materials,
– improved performance aerodynamic propellers in the form of reduced vibration in the feathers of the blades during application of a sheet material, and the availability lead-in front edge and rear edge are profiled with a flare, the possibility of transferring air flow from one pen to another pen of a different profile, noise reduction when working with the presence of the input and output sections of the feathers of the blades, in the absence of flow separation from one pen to another,
– the lack of noise during operation of the wind turbine.
