Rotating wind turbine Bi Plan (ROBIPLAN)

[Remundo]

Hello everybody

I allow myself to create this post to extend the interventions of my friend Pascal HA PHAM who has just deposited and manufacture a new wind turbine concept quite new and promising.

The ROBIPLAN turbine


Pascal HA PHAM is also the inventor of trilobic annular rotary piston machines, which you can discover on this forum linked:

THE VOILA TURBINE ROBIPLAN:

A recreation for one of the little sister of TRILO:

text of the patent specification:

TECHNICAL FIELD OF THE INVENTION:
The present invention is a significant evolution of the concept of the wind turbine.
A wind turbine uses wind energy through a moving assembly powered by natural air currents, this assembly consists of at least two identical and balanced blades mounted on an axis of rotation located "end to the wind", it is the incidence of these blades in the form of a helix that causes the rotation. The axis of rotation is generally fixed and located in a horizontal position relative to the ground and is perpendicular to the plane of rotation of the propeller. The optimum power is obtained by adjusting the settings of 2 major parameters: the incidence of the blades and the orientation of the moving assembly vis-à-vis the direction of the wind.
GENERAL DESCRIPTION OF THE INVENTION:
Unlike wind and all other existing machines fed by natural flows, mobile to elementary streams dual level of nested rotations comes alive in two simultaneous rotations: rotation of a two-bladed paddles -Couple - (BPA) in a first generic plane perpendicular to its axis of rotation (AXR), and the rotation of the rotation axis of the two-bladed in a second generic plane perpendicular to the first (fig 1 and 2). The rotation of the two-axis axis (BPA) is made around its point of intersection with the generic plane of rotation of the pair of blades (fig 2 and 3). During its revolution, the axis of the bipales turns on itself carried and guided by a gallows (POT). The 2 blades constituting the bipales are orthogonal to each other and fixed symmetrically on each side on their axis of rotation. These blades are not in the form of a helix but cut into a preferably constant section profile with two symmetrical leading edges, the blades can also be perfectly flat. Thus, the rotations of the bipales are carried out along an axis whose position varies constantly during the rotary cycle of the stem, alternately having the wind one face and one leading edge, then the other face and the other leading edge, it for one then the other blades whose plans are always angularly offset 90 ° (one relative to the other). The two nested rotations are realized by a cascade of parts, gears, chain and conical couple (CAS) ensuring the kinematics of the relative displacements required simultaneously. It is the rotation of the blades that drives the rotation of the axis of the two-bladed - on itself - via the gallows and the cascade of cinematic parts. One of the pinions of the conical couple is fixed / secured to the support of the assembly. This new arrangement allows an operation ensuring a cycle of alternating passages of each blade from the two-blade to the wind, then through the wind, every quarter cycle, and vice versa. Each blade regularly passes from a zero incidence to a maximum incidence (orthogonal to the flow) in its phase of engagement with the wind, then from a maximum incidence to a zero incidence in its phase of release of the wind (fig 1).
DEFINITION OF CONSTITUENT PIECES:
Bipal definition (BPA):
It is a monolithic assembly of two identical blades fixed in a balanced manner on either side of an axis of rotation, the surfaces of the blades constituting the two-bladed 2 (BPA) are orthogonal relative to each other and symmetrically fixed on each side on their axis of rotation (AXR) Definition of the axis of rotation of the two-blade (AXR):
It is the axis that supports and guides in rotation the two-bladed, it also receives the first drive gear of the kinematic cascade and is supported by a bracket.
Definition of the stem (POT):
This is the rotating support ensuring the second nested rotation of the machine.
It is controlled by the rotation of the two-blade via the kinematic cascade sprocket / chain / tapered torque. It can take a simplified form single arm "L" inverted, or stronger "U" inverted if the power to transmit is important. It must be both resistant and sufficiently perforated / profiled not to oppose too much resistance to the vein of the elementary flow that feeds the machine (fig 2 and 3).

Definition of kinematic cascade (CAS):
It provides quarter-turn rotation of the stem for each quarter of the two-blade engine cycle. The axes of these two elements being perpendicular, it is necessary to use at least one first gear mounted on the axis of the two-blade, a second gear with the same number of teeth on an upper intermediate axis (AIN), a chain for connect the two gears (ratio 1 / 1) and a final conical couple (ratio 1 / 1) with reference to 90 °. One of the elements of the final conical torque is integral with the intermediate axis, the other is fixed on the support of the machine, which is embodied by an output shaft which guides the stem in rotation.
Definition of machine support (SUP):
It is the part which ensures the rotation guidance of the bracket and on which is fixed the second / last element of the conical torque of the kinematic cascade.
This piece provides support for all and allows among other things to fix the machine on a base.

SUMMARY OF OPERATION:
A diagram divides the cycle into 4 phases and allows to visualize the successive positions of the component parts. This drawing illustrates the complete execution of a rotation and helps to understand the movement of the new machine subjected to a wind flow is provided and many perennial: kinematic cascade (CAS) effects rotation by quarter turn of the gallows each quarter motor cycle of the two-bladed (fig 2).
In summary, the mobile elementary flux with two nested planes of rotation operates in the full flow stream delivering a strong average torque, the two-phase cyclically evolves in the 3 dimensions. The ranges of use are very extensive with regard to the accepted fluid speeds and settlements offered by nature. There is no motor breakeven point during the cycle.
The machine can also operate against a hydraulic flow, or reversibly compressor / fan when its stem is rotated by an external motor.
In each case, the surfaces, dimensions and materials of the component parts must be re-examined, dimensioned and adapted to the required use.

On a cycle (a turn of the gallows), the average driving surface of the two-way beam exposed to the flow (in orthogonal equivalence) is identical to the surface of a blade.
On a cycle, the maximum surface swept by an asymmetrical bipales type "a square blade and a half-moon blade" is less than 2 times the added torque masters 2 blades.
It is thus more than half of the area swept by the bipales that can be constantly active, (equivalence orthogonal to the flow).
If asymmetric blades are used, dynamic balancing is required.
The maximum compactness rate of this wind machine can therefore be greater than 50% (ratio between the active surface orthogonal equivalence and the area swept by the biphase on a cycle).
Two prototypes / functional demonstrators were built end 2007 beginning 2008.

here ..... I do not know if someone had already been able to rotate the driving part of any rotating machine around a single fictitious point ... with a minimum of torque almost constant to the key .. ...

now it's done ...! here is
the rotation cycle of the ROBIPLAN blades is efficiently performed in the 3 dimentions ....
