Adaptive Materials and Michigan students set record fuel-cell-powered UAV flight
The longest fuel cell powered flight of a radio-controlled aerial vehicle has been achieved by students at the University of Michigan and engineers at Ann Arbor-based fuel cell manufacturer Adaptive Materials, Inc.
Their plane, named Endurance, flew for 10 hours, 15 minutes and 4 seconds in a flight that lasted from sunrise to sunset on Oct. 30, 2008 at Field of Dreams Park in Milan, Mich. The previous world record, held by a California-based company, lasted just over 9 hours.
The student SolarBubbles team built the airframe, which has an 8-foot wingspan. Adaptive Materials funded the project and built the aerial vehicle's propane-powered solid oxide fuel cell. The Adaptive Materials fuel cell for the aerial vehicle was a hybrid battery system.
"It's great to be at the forefront of aerial vehicles," said Nick Rooney, a senior aerospace engineering undergraduate who is leader of SolarBubbles. "I'm really excited about this and proud of all the people who have worked on it."
Adaptive Materials has worked extensively in the air vehicle space, and will work with SolarBubbles to achieve a 20-hour test flight.
"It's critical for unmanned aerial vehicles to have extended flight times to provide the functionality needed for military missions," said Michelle Crumm, chief business officer at Adaptive Materials. "The flight time achieved with the SolarBubbles team surpassed any of Adaptive Materials' previous work with aerial vehicles and shows that we're just scratching the surface for what's possible with a lightweight, reliable fuel cell."
Endurance had enough fuel to fly for five more hours, but it had to land at dusk because it wasn't made to fly at night.
The plane flew almost 99 miles over the course of the day as students took turns flying it in a holding pattern.
The SolarBubbles team designs, builds and tests unmanned aircraft. In addition to this fuel cell project, students are working to build a solar-powered unmanned aircraft with a wingspan smaller than 15 feet that can fly for more than 36 hours
