The World's First Solar-Powered Helicopter Takes Flight

      As projects like the Solar Impulse and NASA's Helios wing has been recently developed, the idea of propelling aircraft using solar power isn't as fanciful or impossible to accomplish as it seemed before, even if they are still in experimental stages. Before long, we'll surely be able to see solar power used to aid traditional airplanes, even if it is not accompanied by main fuel.
     To show what is possible, a team of master students from the United Kingdom have built what they believe to be called the world's first "solar-copter," a quadrotor that flies solely on solar power. At the moment, it is capable only of short flights but the team had claimed that it should fly longer soon, once they enabled it to have a storage system as well.

     "The Solar-copter is a quadrotor design that incorporates a solar panel providing the power for the propulsion system," the six students had commented. "It is controlled in the same way as a standard battery-powered quadrotor. Optimum thrust-to-weight ratio was mainly achieved through an efficient propulsion system, unique frame design and an optimized solar panel."

     Future versions may be useful in activities such as surveillance, search and rescue, and tracking animal migrations, perhaps in Africa, Australia, Middle East, and Southern Europe, where there is more sun than in England. Its technology could also help increase the range of conventional choppers, and perhaps give other solar aircraft, such as the Solar Impulse, better maneuverability and control.
