#1 h(dt)^2

 Previous years Thiran projects are a big source of knowledge . ACCET NEWS now comes up in bringing all the posts you need from the past!     
 Here comes the H(DT)^2 series -'How Do They Do That'

      Hybrid Vertical Axis Wind Turbine
                                  - THIRAN version 2014

         Everyone can't have a conventional horizontal axis wind turbines on their roof!! Here comes TECHWIZARD'S with their specially designed "Hybrid Vertical Axis Wind Turbine" to eliminate this issue. 

Components required:
1.Aluminum foil       (from a paper press in Karaikudi near five lamps.)
2. Belt and pulley    (was brought from a hardware shop.)
3.Wheel                 (was brought from a cycle shop.)
4. Shaft                 (was bought near old bus stand and machined near periyar selai.)

   /*All the materials were brought around Karaikudi.*/                                                                                  
   /*Few were from thiruvaluvar illam(actually seniors).*/

Fabrication of HVAWT :

1. The design template of the blade is drawn on aluminium sheets.
2. It is then cut & folded into suitable aerodynamic shape.
3. The blades are attached to the wheel which is pivoted to a fixed shaft.
4. A DC generator and the rotating hub of the wheel are connected by means of a belt drive.
5. A suitable load is connected to the generator and production of electricity is tested successfully. 

DESIGN CONSIDERATION :

Economic sustainability : The turbine was made out of inexpensive materials, most of which can be purchased                                           locally in Karaikudi. 
— Environmental consideration : Any contribution to the field of green energy, such as wind turbines, can help to                                                 shift energy production away from fossil fuels and toward renewable resources.
— Manufacturability : The turbine has potential to be created by any person with some degree of mechanical                                        aptitude because of its simplistic design.
Bottom view!
Working of our "HVAWT":  
— The wind imposes two driving forces on the blades of a turbine; lift and drag. Lift and drag are the components of this force vector perpendicular to and parallel to the apparent or relative wind, respectively. By increasing the angle of attack, the distance that the leeward air travels is increased. This increases the velocity of the leeward air and subsequently the lift.

Advantages over HAWT (conventional Horizontal Axis wind turbine)
— The propellers and turbine mechanisms are mounted high above the ground on a huge pedestal. The height at which their mechanisms are located is a disadvantage when servicing is required.
— They require a mechanical yaw system to orient them such that their horizontal axis is perpendicular to and facing the wind.
During Demo session!
— Potential power generation is related to the swept area (diameter) of the rotor, more power requires a larger size of turbine blade.
