ENERGY CONVERSIONSlide4
STATIC WIND TURBINESDYNAMIC WIND TURBINESIt is stationary and fixed in place.It is mobile.
Wind turbines are huge and costly.
It is very small in size and cost effective.Installation is difficult and it requires a huge space.Installation is easy and requires less space.Can be installed only in high wind areas.Can be installed in all vehicles.COMPARISON OF STATIC & DYNAMIC WIND ENERGY CAPTURESlide5
DESIGN OBJECTIVESMinimize drag Maximize power.Harness energy from the wind.To develop a powerful, cheap, light, low drag, simple, dynamically stable and durable prototype ram air turbine.

PROPOSED APPLICATIONSlide17
Integration of Ram Air Turbine in the vehicle.Storage problem in batteries. This energy production produces no pollution and it is clean free energy and it is a great social relevance at
present times with the world going green. It is very cheap to harness this energy.
Energy production is continuous and reliable. Unlimited free wind energy is available around us.PROBLEMS TO OVERCOMEADVANTAGESSlide18
