Web27 mei 2015 · Solarcopter is a direct sunlight powered helicopter. It is a remote control quadcopter UAV able to continuously fly in sunlight without any need for energy storage. The prototype successfully flew under irradiance of 1000 W/m2 and achieved a thrust to weight ratio of 1.36:1. Web1 HP = 764 Watts. And in theory, you can fondly get a rough idea of the horsepower of an electric motor by taking its rated current draw (amperes) and multiply it by the voltage. That is: Power (watts) = Current Draw (amps) x Voltage. So here you get a rough thrust to horsepower equation: Horsepower (hp) = current draw (amps) x voltage/764.
