Abstract

A vertical axis wind or water turbine has at least one rotor 1, 2 with drag type blades 3, 4 shaped as hollow aerofoil shaped blades which are convexly shaped and which narrow towards leading and lateral edges. The blades 3, 4 may be asymmetrical or symmetrical. Plural rotors may be counter-rotating. The blades may be connected to the rotor by means of winglets 41, to allow pitch (figures 52-55) or tilt (figures 60-63). Circular fluid deflectors/diffusers may be placed above and/or below the rotors, and may have collar panels mounted on them. Each rotor may have more than one row of blades, which may be vertically aligned or mis-aligned.

Description

Device for fluid kinetic energy extraction and conversion
Background art
At the moment there are several vertical axis technology concept (VAWT) for wind or fluid kinetic energy extraction and conversion into electric energy like savounius, darrieus, gyromill, magnus, vortex etc. but none of them had archived or surpassed HAWT (horizontal axis wind turbines) efficiency.
Statement of invention
To overcome this problem this application presents different solution for fluids kinetic energy extraction and conversion with vertical rotation axis which is more efficient than any other vertical axis solution. The solution described within this application is based on novel hybrid lift-impulse blades which can work well at one rotor alone but works even better in synchronicity with other counter rotating rotor with oppositely oriented blades. Each blade is shaped as hollowed asymmetrically or symmetrically air foiled shaped blade which narrowing toward leading and lateral convexly shaped edges. In this way it is created blade which take the best from impulse effect of moving fluid as well from aerodynamic lift-push effect of blade moving through fluid. For better performances each blade of rotor will have radii at outer side of leading and lateral convex edges as well as at their inner sides. When there are two or more rotating rotors each rotating rotor will have oppositely oriented blades in which way overall efficiency system is increased by using positive wake effect as well mutual beneficial aerodynamic interaction of blades and beneficial fluid directing as it pass from one rotating blade to other one counter rotating blade from oppositely rotating rotor. In addition blades of oppositely rotating rotors may be placed in groups so that one device for fluid kinetic energy extraction and conversion may have two or more groups of blades of rotors rotating in one direction and above or below this group of blades may be another group of blades of two or more columns of blades belonging to other rotor rotating in opposite direction. Blades with rotor may be connected gapless or with some gap among blades and rotor in which case blades will be connected with winglets with rotor and the rotor and device for fluid kinetic energy extraction and conversion which use this kind of rotors will have somewhat different performances.

Detail description
The solution described within this application is based on novel hybrid lift-impulse blades 3 which can work well if there is only one rotor 1 alone but works even better in synchronicity with other counter rotating rotor 2 with oppositely oriented blades 4. Each blade 3, 4 is shaped as hollowed asymmetrically or symmetrically air foiled shaped blade which narrows toward leading edge 8 and lateral edge 9 which are convexly shaped. In this way it is created blade 3,4 which take the best from impulse effect of moving fluid as well from aerodynamic lift-push effect of blade 3,4 moving through fluid. For better performances each blade 3,4 of rotors 1, 2 may have radii 10 at outer side of leading convex edge Sand lateral convex edge 9 as well as radii 17 at these edges inner sides. When there are two or more rotating rotors each rotating rotor 1, 2 will have oppositely oriented blades 3, 4 in which way overall efficiency system is increased by using positive wake effect as well mutual beneficial aerodynamic interaction of blades 3,4 and beneficial fluid directing as it pass from one rotating blade to other one counter rotating blade from oppositely rotating rotor. Examples of asymmetrical air foiled profiles 15, 16, 37, 38, 39, 49, 50 and symmetrical air foiled profiles 44, 45, 46 can be seen on figures. In addition blades of oppositely rotating rotors may be placed in groups where each rotor 1, 2 have two or more columns of blades, 3,4, 47, 48. Dependably of desired features of device for fluid kinetic energy extraction and conversion 11 these columns of blades 47,3 for rotor land 4,48 for rotor 2 maybe be aligned vertically or may be misaligned as could be seen on figures where blades 47,4 are misaligned relative to blades 3 and blades 48 for 60 degrees. Of course the value of misalignment may be anywhere from almost 0 degrees to almost 360 degrees. Blades with rotor may be connected gapless or with some gap among blades 3,4 and rotors 1, 2 in which case blades 3,4 will be connected with winglets 41 with rotor 1, 2 and the rotor 1, 2 and device for fluid kinetic energy extraction and conversion 11 which use this kind of rotors will have somewhat different performances. When there is a space between blades 3, 4 and rotors 1, 2 blades maybe be pitch controlled by means of pitch motors 42 with 360+ degrees of rotation around motor 42 central axis of rotation. When there is a space between blades 3,4 and rotors 1, 2 blades maybe be also tilt controlled by means of motor 43 around central rotation axis of motor 43 with +-90 degrees of rotation. Pitch and tilt control of blades 3,4 may be combined and appropriate software controlled.
How does device for fluid kinetic energy extraction and conversion 11 work? At device for fluid kinetic energy extraction and conversion 11 support pole 6 are immovably placed stators 51 with wire windings 13. Around stator 51 are placed counter rotating rotors 1, 2 inside which are placed magnets chambers 40 in side which are placed permanent magnets or electromagnets 14. Stators 51 are moveably connected with rotors 1, 2 by means of angular ball bearings (or some other type of bearings). At the top of device for fluid kinetic energy extraction and conversion 11 is placed top cover] which is immovably connected with stators 51. Instead of at least two counter rotating rotors 1, 2 device for fluid kinetic energy extraction and conversion 11 may have just one rotor 1 or 2 with just one stator 51 but in case of just one rotor efficiency will not as high as in case of counter rotating rotors. If there is only one rotor again blades 47, 3 or 4, 48 may be placed in columned groups which may be vertically aligned or misaligned. There are many different variations of how these groups of blades may be grouped and combined and their configuration will depend from desired rotor or rotors technical characteristics.
When fluid interacts with blades in combined impulse and aerodynamic ways blades 3,4 start to rotate rotor 3 or 4 or rotors 3, 4, if there is more than one rotating rotor, which cause rotation of magnets 14 around wire windings 13 which induce electric energy inside windings 13 in which way is energy of fluid converted into electric energy.
In other embodiment of device for device for fluid kinetic energy extraction and conversion 11 at the top of stator or stators 51 may be placed circular fluid deflecting base 18 with circular air diffuser 20. Circular fluid deflecting base 18 may be convex, concave or flat while circular air diffuser 20 maybe also be concave, convex or flat. At the circular fluid deflecting base 18 may be placed fluid directors 19 while at the circular air diffuser 20 may be placed fluid directors 21. At the sides of circular air diffuser 20 may be placed devices for solar energy conversion 22 and at the top of circular air diffuser 20 cover 26 may be placed devices for solar energy conversion 23.

At the circular fluid deflecting base 18 may be placed fluid directors 19 while at the circular air diffuser 20 may be placed fluid directors 21. At the sides of circular air diffuser 20 may be placed devices for solar energy conversion 22 and at the top of circular air diffuser 20 cover 26 may be placed devices for solar energy conversion 23. In the same time at the bottom of stator or stators 51 may be placed circular fluid deflecting base 27 with circular air diffuser 29.
