AEROPAK, a next-generation fuel cell power system recently developed by Horizon Fuel Cell Technologies will increase the flight endurance of small and stealthy electric unmanned aerial systems (UAS) by as much as 300 percent. The fuel cell technological advancements will bring significant enhancements to UAS, making them more effective in persistent intelligence, surveillance and reconnaissance (ISR) missions, a main focus area for leading defense and security organizations around the world. Starting evaluation shipments this summer, Horizon’s new AEROPAK brings an immediate performance improvement over today’s best available battery systems. Designed for high-impact and able to operate at up to 22,000 feet (6500m), the complete system integrates Horizon’s record-setting fuel cell technology with new refillable dry-fuel cartridges. Storing 900Wh of usable electrical energy and weighing just 4.4 lbs (2kg), the AEROPAK provides up to four times the endurance capability of advanced lithium batteries currently in use. The miniaturized power system makes it very easy to use as drop-in replacement for battery packs currently in service, eliminating costly airframe modifications. According to G2 solutions, a Seattle-based market research firm specializing in Aerospace/Defense, “The use of pervasive UAS is increasing because the persistent ISR capabilities they bring are unmatched". Electric-powered UAS bring important capabilities - reduced acoustic signature, smaller size - and offer real advantages - lower acquisition cost, fuel savings - to ISR operations. Where battery performance limits the effective use of these promising systems, the AEROPAK next-generation fuel cell power systems will improve versatility and open new mission possibilities for smaller electric UAS. In addition to increasing flight endurance, the new fuel cell system also makes it possible for small tactical UAS to integrate more power-hungry electronic devices such as electro-optical sensors, infrared cameras and laser designators. The new fuel cell systems can also be used to power remote ground systems and recharging stations, or even serve as an auxiliary electric power supply for larger systems. Horizon’s AEROPAK is the first of a series of commercially available fuel cell systems that can be customized to fit a variety of platforms and scaled up to provide as much as several kilowatts of power, making it suitable for all sizes and configurations of electric powered UAS. Over the next 10 years, industry analysts expect the acquisition market for UAS to exceed $44 billion in the U.S. alone. According to Ron Stearns of G2 solutions, “Fuel cells have the potential to improve the Size, Weight and Power (SWaP) configuration for tactical UAS propulsion, leading to increased UAS endurance or expanded sensor and/or communications-relay capabilities".
