  • I want to present a small group in Romania that have invented
    a NEW (NOT UPDATED) revolutionary HAWT rotor blades! This invention isn't internationally patented (in Belgium) and doesn't have its final Marketing form due to lack of funds and this is the reason the Romanian group wish to talk, explain and associate to 1 of the most 11 globally known turbine + blade manufacturers [the NEW product should be through the R&D phase, testing phase (i.e. wind tunnel, comparing tests, several different wind turbine sizes testing etc.) and Global Sales&Marketing phase] such as: GE, LM, Enercon, Fruhlander, Gamesa, Nordex, Repower, Siemens, Suzlon, STXwind, Hyundai.

    Please don't hesitate to contact me for further info.

  • I just wanted to add that Mr. Gherca Ionel and myself collaborate in other GREEN projects. In this specific project, the principal inventor is a Romanian researcher whose identity will remain anonymous for the time being. At the time we sign an NDA with Suzlon company management will be introduced the principal inventor. Until then, Mr. Gherca Ionel is the direct contact person and myself should be in CC. At all times Mr. Gherca Ionel will communicate with the principal inventor all communications between Suzlon Company and Mr. Gherca Ionel.

    The blade rotor drawings in the attachment have nothing to do with the new blade invention form proposed by us. WHAT WE ARE PROPOSING HERE IS STRICT PURELY VERIFIABLE ALTHOUGH AT FIRST GLANCE YOU MIGHT THINK IT'S IMPOSSIBILE, UNREAL AND IMPRACTICAL!

    The Company who's going to join us, will become the most important player on the global wind market because all windmill buyers would like to have such turbines reaching their full capacity (100%) at a wind speed of only 7 to 8 m/s. We think it's needless to say that nearly all existing Wind farms are built in areas with average wind speed of 5 to 7 m/s. Hence, this new invention will at least double a wind turbine's power production capacity at low and medium wind speeds. To better understand the potential of this invention we'd compare it with jet engines (reaction engines) and compared with classical propeller engines in airplanes. By the way, Reaction Motor was invented also by a Romanian inventor.

    Please don't hesitate to contact us for further information.

    Sincerely,

Wind rotor blade - invention promotion

  1. 1. Technical performance improvement proposal for wind rotors with mediumand large power (medium and large wind blades with superior characteristics)Wind turbines convert wind power into electricity power or mechanical energy. Their interfacefor acquiring the wind’s energy is the multiple-blade rotor. The preliminary material is mainlyfocused on creating the concept, executing and optimizing the rotor blades for medium and largesized turbines (higher than 100 kW), which would start at low wind speeds (below 1.5 m/s).This concept has a specific area of implementation (with low wind potential), is characterized bysimple technology execution and installation, low cost and easy maintenance. In dynamicregime, the rotor – consisting of the main shaft and blades – covers during a turn/completerotation a certain surface, thus generating power into the system. Classic blades with airfoilshape are generally three (3) in number and are made from composite reinforced withfiberglass, plastic, metal or wood. The proposed solution has the following advantages: Wind turbines start at low wind speeds (below ~1.5 m/s); Achieve maximum power at ~8 m/s; Changing the aerodynamic shape of the blades will decrease the air resistance and mitigate the von Karman, von Katzman and the Coanda effects; Remodeling the blade geometry and aerodynamic shape, the torque will increase due to the enlargement of the bearing surface; Comparing with a standard rotor with classic blades, but with similar diameter, the noise level will drop significantly (lower by up to ~30%); The power of the system (generator power) can be maintained at the same value while decreasing the rotor’s diameter with around 25–35%; In dynamic regime, the elasticity of the new blades will determine the functioning of the rotor even at high wind speeds. In the case, the rotor will enter a self-braking stage without the use of additional mechanical or electromechanical systems; Copyright © 2012, ROMANIA
  2. 2. While operating the rotor will behave like a balance wheel (flywheel), which gives it the advantage to keep its speed of rotations constant during wind speed variation (in a certain range of values); The rotor blades weight will significantly decrease compared to a classic rotor having the same diameter (about 20%, depending on the blade material); In order to obtain the same shaft torque with the new blades, the diameter of the rotor will be reduced with about 25%; Service will be easier and faster; It will be possible to obtain the rated power of the turbines at power heights.To achieve these improvements in wind rotors technology (rotor already patented but secret fornow) collaboration is needed in terms of technical, economic, human resources and funds by theparties to be involved. In order to optimize the results for this application towards large andvery large turbines, it will necessary to develop innovative experimental models of turbinesusing at least two (2) medium power wind turbines (100–500 kW) for the execution andoperation of prototypes. We look forward to collaborate with a company that has financialability, logistics and necessary equipments and is willing to invest them for the achievement ofthis objective.Invention PromoterOn behalf of the Romanian R&D teamTechnical support – Ec.
