The First Solar Designed for HALE UAVs
Until now HALE UAVs have used solar that was designed for terrestrial or space environments. Now, the first solar product design for HALE aircraft is available.
The stratosphere at an altitude of 20km (60,000 feet) poses unique engineering challenges to aircraft due to the harsh conditions. High levels of UV radiation, ozone and thermal cycling are present which can damage materials and greatly accelerate degredation. In addition, the solar spectrum is different at stratospheric altitudes which affects solar efficiency. All these factors drive the need for a specialized solar product for HALE.
This new product combines world record solar efficiency with cutting edge materials science and several new inventions that maximize power, minimize weight and extend durability in the stratospheric environment.
