2 AÉROGÉNÉRATEUR BSB AEROGENERATEUR BSB is a vertical axis wind turbine; its rotor is of type "Savonius" with variable geometry. PRINCIPLE AEROGENERATEUR BSB is a geometry variable, stackable, and vertical axis wind turbine coupled with a synchronous electric generator (permanent magnets). AEROGENERATEUR BSB consists of a welded structure maintaining the rotor position but also accelerating the wind penetrating across (venturi effect). The rotor consists of 4 blades in circular form semi composite and forming a quarter of a torus. The blades have a degree of freedom about a vertical axis of rotation, allowing modification of the decision-making to the wind. This form allows, when the 4 blades are closed, to form a torus removing any decision-making in the wind. Training for the electric generator is done online, without speed box or Gable. VARIABLE GEOMETRY Storms or extreme wind (45-55 m/s) it neutralizes the rotor to avoid destruction. OPEN ROTOR When the rotor is completely open, it allows a startup with winds of very low speed (1.5 m/s) Page 2

3 AÉROGÉNÉRATEUR BSB CLOSED ROTOR When the wind reached a dangerous speed for the machine, the rotor automatically closes. AEROGENERATEUR BSB has a diameter of 8 meters, it provides a power of 15 kw for a wind of 12 m/s. Its maximum power at 60 kw for a wind between 25 and 45 m/s. Page 3

4 AÉROGÉNÉRATEUR BSB Stacking the AEROGENERATEUR BSB it multiplies the power! We create "wind turbine towers". TECHNICAL CHARACTERISTICS Dimensions: ± 8 m, height ± 2.5 m diameter Page 4

5 AÉROGÉNÉRATEUR BSB estimated average power: 15 kw, for a wind of 12 m/s estimated maximum power: 60 kw, for winds of 25 to 45 m/s alternator Type: synchronous generator with permanent magnets direct Transmission without multiplier. Total weight: ± 2500 kg startup speed: 1.5 m/s nominal speed: 45 m/s decision speed: 55 m/s 4 blades thermoplastic fiber glass optimal rotor speed: 80 RPM Diameter of the rotor: 5-8 m (variable geometry) BENEFITS OF THE CONCEPT The advantages of the design are multiple: Congestion well below the horizontal axis wind turbines, power equal. AEROGENERATEUR BSB occupies 4 times less than volume that a wind turbine to power traditional horizontal axis HAWT equal. Its size represents a low height cylinder while HAWT uses a spherical volume whose diameter is equal to the height. Speed constant and regular and slow for operation without noise. AEROGENERATEUR BSB is variable. Slow rotation rate is almost constant. The diameter of the rotor decreases at the as the wind speed increases and vice versa. It is possible to automatically adjust the start of the closure of the rotor and its total closure and/or piloted remotely. Possible stacking: Multiplication of power without increasing grip on the ground. It is possible to stack AEROGENERATEUR BSB on multiple heights and thus multiply its power without the use of additional floor area. Of course, it is impossible to do the same with a HAWT! Ease of adaptation in urban areas (building roofs) in virtual invisibility! Size and shape AEROGENERATEUR BSB allow architects to easily incorporate it into buildings that they draw. Many of the existing buildings can be equipped AEROGENERATEUR BSB and thus become self-sufficient by participating actively in the efforts for the preservation of the planet. Direct-drive of electric generator without box speed or reference: Elimination of the risk of failures and the preventive and curative maintenance costs reduction. Magnet alternator AEROGENERATEUR BSB standing is to slow rotation. Its large diameter allows an excellent distribution of the masses and a direct drive without multiplier. Most of the HAWT need a gearbox to multiply the number of revolutions per minute and a system of rotation on mat. These mechanical require frequent maintenance and are recurring sources of failure. Distribution of the masses on the surface of AEROGENERATEUR BSB lower Foundation costs and ease of implementation (50 kg/m²) The reversal is much lower than with a HAWT; structure requirements are greatly reduced. His editing is perfectly feasible on the boats. Insensitivity to the turbulence and rapid changes in wind direction: increase productivity! Page 5

6 AÉROGÉNÉRATEUR BSB Often, the wind changes direction suddenly: AEROGENERATEUR BSB is always in the same sense, regardless of the direction of the wind and the speed of change: AEROGENERATEUR BSB " is insensitive to wind breaks! A HAWT will take time to rotate on its axis, causing huge efforts on the rotor, and thus on the overall structure of the wind! Insensitive to differences in windspeed with altitude unlike the HAWT! The wind speed is often different depending on the height. The rotors stacked and independent "Wind turbine BSB " adapt perfectly to this situation. On a HAWT, at least a pale slows the other two; There is therefore a significant loss of performance and asymmetric axes efforts cause significant mechanical wear. Safety: elimination of the risk of ejection of the blades in a cage structure The risk of breakage of a blade is extremely reduced because of its variable geometry; It eliminates any decisionmaking in the wind during strong storms, or even a simple "gust of wind". Accessibility of the simplified machine: easier maintenance! The simplicity of AEROGENERATEUR BSB is a robust machine that requires little maintenance: some bearings with grease regularly and stroke of paint... A staircase or a crinoline scale allows access in height for the internal spacers. A permanent crane can be fixed partly upper structure to great heights. Removal of the network of high voltage power lines POSITIONING & GLOBAL market 1 Positioning of AEROGENERATEUR BSB on the market AEROGENERATEUR BSB is located in a range of "Average power", between domestic or small type wind turbines wind - up to 36 kw - and industrial turbines or great wind from 350 kw to 4 MW. This range of power is little developed; there is very little competition in this segment. AEROGENERATEUR BSB is primarily intended to provide electricity locally, but connects to the existing emergency network. Don t need network of high voltage power lines INFORMATION Whereas an average power of 15 kw and knowing that a home French generally consumes kw/h per year, "Wind turbine BSB " can power about 25 dwellings. In the way of developing countries, AEROGENERATEUR BSB can feed 100 to 250 units on average, according to expressed needs, alone or in association with other complementary energies... 2 CUSTOMER POTENTIAL Page 6

These needs slowed by the inevitable increase in the cost of fossil fuels and environmental awareness of States and peoples are the part of the "sustainable energy" becomes very important in the world. For example, the installed capacity of the Earth's wind farm French is about 7 GW; the objective of the Grenelle of the environment is set to 19 GW à L'Horizon 2020 for the land and 6 GW offshore. AEROGENERATEUR BSB is ideally placed in the electricity supply: It can both be implemented independently in areas where electricity is not insured, while ensuring the interconnectivity of networks of the developed regions. The ease of implementation of AEROGENERATEUR BSB via a small footprint increases dramatically the number of potential sites, unlike the horizontal axis high power HAWT wind that require larger exploited surfaces and developed road infrastructure... The foundations of 2 MW horizontal axis wind turbine may require up to 100 trucks-top of concrete! AEROGENERATEUR BSB provides a source of electrical supply for machines in areas devoid of electricity... CONCLUSION Of the available powers clearly representing the expressed needs of buyers! Of the powers currently failing in intermediate range on the world market! A proven compactness, relative to the available powers! A stacking of the "wind turbine BSB " to multiply the powers without additional grip! Insensitivity to gales and all undesired changes of wind direction! A preventive security by disabling progressive & automatic climate-related! Security active via mounting cage, limiting any projection in the event of failure or partial destruction! An implementation claiming little specific equipment: pre mounting workshop and delivery in kit! A preventive maintenance reduced to its simplest expression, accessible to a traditional mechanic! A curative maintenance facilitated by easy handling of the parts, even at great height!
