UAVOS has successfully completed the first flight of a 10 m wingspan prototype of its ApusDuo solar-powered high-altitude pseudo satellite (HAPS) for the first time, the Mountain View, California-based company announced in mid-October.
The ApusDuo HAPS prototype has a maximum take-off weight (MTOW) of 23 kg and a payload capacity of 2 kg. It adopts a tandem wing design comprising fore and aft wing surfaces that are connected by three equally spaced booms that terminate in a vertical fin and rudder assembly. This supports the aft wing that carries the three electric propulsion motors. The motors draw power from fuel cells that are recharged via photovoltaic (PV) arrays covering its upper wing surfaces.
