Horizon Energy Systems (booth 2828) is at the show to launch commercial sales of its Aeropak hydrogen fuel cell power system, designed to bring a 300% flight duration improvement to today's battery-operated 5-10kg class mini-unmanned air vehicles (UAV).
Israel Aerospace Industries (IAI) has provided a major shot in the arm for the project by announcing that it is adopting the Aeropak as a power system for its Bird Eye 650 unmanned air system.
