Wing Sail Land-yacht Modeling And System Verification

Wind-driven vehicle is a kind of promising way to utilize wind energy due to its non-pollution feature. This paper presents a practical design of the wind-driven vehicle in the form of land-yacht, which is equipped with a wing sail and a micro-controller unit. Theoretical analysis and simulation were performed to find the total force coefficient corresponding to each combination of attack angle and heading angle, and the best attack angle corresponding to each different heading angle. A prototype was built and tested in a wind-field environment. The simulation and experiment were concordant, both of which showed the relation between the movement of land-yacht and these angles when moving upwind well.
