It makes it possible to provide renewable energy in the heart of cities, by being perfectly integrat
2、ed, aesthetically and technically, in the built structures. It is adapted to highly turbulent urban winds and to modern architectural constraints.2Aerodynamic Characteristics:The axisymmetry of the STATOEOLIEN enables it to be totally independent from the wind direction changes. Indeed, the fixed wi
3、ngs of the stator and the moving blades of the rotor are distributed in a symmetrical way around the vertical shaft of the machine, thus supporting no privileged operating direction. The result is an optimal working whatever the wind direction, which is particularly useful with urban winds, that are
4、 characterized by frequent direction changes.3Principle of the stator (1)Using a stator offers three main advantages :1. The stator allows the flow to beoptimally canalized tangentiallyto the rotor blades, in order togenerate maximum power.42. The stator offers the possibility to integrate into the
5、turbine a rigid tubular structure, that allows the STATOEOLIEN to resist violent winds. This structure surrounds the rotor and maintains it strongly, thus absorbing mechanical strains and aerodynamic vibrations (swirls on rotor blades, periodic variation of the torque applied to the shaft,.).Princip
6、le of the stator (2)5Principle of the stator (3)3. When the rotor blades exposetheir leeward side to the wind,they generate a torque that willoppose the normal workingrotation. This results in powerloss. Therefore the stator hasbeen designed to generate in this“brake“ zone turbulences that willpreve
7、nt wind from entering themachine and pushing the bladesin the wrong direction, thusreducing this braking effect.6The rotor blades have been designed to generate maximum power, whatever their position in relation to the wind direction. Their shape proceeds from the results of complex aerodynamic stud
8、ies (CFD simulations). They are built on the same principle as modern aircrafts wings (technique known as “Skin + Ribs“). This process allows the rotor blades and the stator wings to be not only rigid but also very light.Rotor Blades and Stator Wings (1)7The anchoring system of the rotor blades and
9、stator wings makes the assembling and the disassembling particularly easy. Thus, the installation and maintenance of blades and wings become very simple (checking, cleaning, and changing).Rotor Blades and Stator Wings (2)8Mechanical Characteristics (1)Rigidity of the stator structureThe tubular stru
10、cture of the STATOEOLIEN allows it to resist 200 km/h winds, while remaining compact and aesthetic (Wire stays or external anchoring systems are not required to reinforce the structure).Besides, stator wings and rotor blades are held by their two ends, which eliminates mechanical stability problems
11、due to cantilever assembly. Indeed, the fastening of an aerodynamic profile (such as an aircraft wing or horizontal axis wind turbine blades) results in mechanical instability which causes vibrations and strain of the materials. 9Moreover, the STATOEOLIEN does not require the use of a pylon when it
12、is set up on a building : it can be installed directly on the structure of the roof. Yet a pylon may become necessary when there is no building to receive the machine (installation in Isolated environment, water pumping.).Mechanical Characteristics (2)10Structures comparisonComparison between a cant
13、ilever structure (left hand) and a structure fixed at both ends (right hand). The first one is mechanically unstable (vibrations, high stress constraints applied to fixations). On the other hand, the second one transmits the efforts and vibrations to both fixations, leading to maximum stability.11Ro
14、tor LightnessThe whole rotor is made in aluminium, in order to reduce weight, and thus enabling it to adapt instantaneously its rotation speed according to the wind speed.12Easy IntegrationThe compact cylindrical shape of the STATOEOLIEN allows it to be adapted to all architectural patterns. It can
15、be perfectly integrated to horizontal or sloping roofs.13Examples of STATOEOLIEN integration14Working in torque and not in speed rotationThe STATOEOLIEN working is linked to the torque and not to the Rotation speed, leading to a reduced linear speed of rotor blade tips. While Horizontal Axis Wind Tu
16、rbine blade tips can easily reach 400 km/h, the STATOEOLIENs blade speed does not exceed 85 km/h, which reduces dramatically the centrifugal forces on the blades. In addition, low speed rotation offers an improved safety level (reduced emergency stop delay).15Vibrations absorptionThe whole tubular structure of the STATOEOLIEN has been studied to genera
