SINGAPORE -- 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 AEROPAK brings an immediate performance improvement over other battery systems. Designed for high-impact and able to operate at up to 22,000 feet (6500m), the complete system integrates Horizon's fuel cell technology with refillable dry-fuel cartridges. Storing 900Wh of usable electrical energy and weighing 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 easy to use as drop-in replacement for battery packs currently in service.
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."
In addition to increasing flight endurance, the 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.
"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," says Ron Stearns of G2 solutions.
