A wind turbine is the turbine that you will see installed in most open areas. It uses the mechanical energy of the wind and converts it into the kinetic energy. The kinetic energy is further converted into the electrical energy through a set of different equipment. This process has proven to be a great aid to many people who were burdened with exorbitant electricity bills. More and more people want to know how to make their own wind turbine.
The material used in the blades of a wind turbine is the PVC sheets or the glass reinforced (GRP) plastic. The GRP happens to be the best and popular choice for making the wind turbine as this is coated with epoxy resin matrix. This coating prevents it from corrosion and thus improves the life.
In earlier times when there wasn’t much knowledge about how to make a wind turbines properly, people used cardboards, canvas and even wooden blades. These not only lacked the required aerodynamics capabilities but they corroded and decayed very fast. Some people opted to use aluminium sheets to make the rotor blades. However, these also corrode over a period of time.
With advent of time, people gathered more information on how to make a wind turbine. The axis of the wind turbine can be of two types. It can be the horizontal axis or the vertical axis. Horizontal axis is usually chosen over the vertical axis. This favours the wind movement through the blades thereby effectively generating electricity.
Another important aspect in constructing the wind turbine is the length of the tower. Most of the towers are very tall reaching the height of up to 10 meters. This is a very good place to keep the blades moving. There is very little or no resistance in the air at that height. The absence of polluting elements removes the possibility of any friction. Thus the drag is minimal.
The number of the blades to be installed depends on the nature of the job, handling ability and most importantly the budget. You have to have a realistic approach for the implementation of your plan. In general we can say that how to make a wind turbine is not a very difficult task. The raw material, PVC or GRP is easy to get and is inexpensive. It is not too complicated to work on it and of course performance is superb. Once the appropriate sized blades are cut, you can move forward.
