6.Aurora Flight Sciences Odysseus
The Odysseus solar-powered UAV pushes autonomous flight capability limits. Although it weights less than a small vehicle, this huge drone has a wingspan almost matching that of a Boeing 747. Its ground-breaking design maximises power generating efficiency by including flexible solar panels that fit the form of the aircraft Operating constantly for months at heights exceeding 60,000 feet, the Odysseus can provide constant surveillance and communications relay services. Its sophisticated autonomous systems help it to negotiate challenging weather conditions while preserving ideal solar exposure.
