The 247-foot length of the Helios prototype wing is in evidence as the solar-powered flying wing rests on its ground dolly during pre-flight tests at the U.S. The Helios Prototype flying wing is shown near the Hawaiian islands of Niihau and Lehua during its first test flight on solar power from the U.S. The Helios Prototype flying wing is shown near the Hawaiian island of Niihau during its first test flight on solar power from the U.S. Navy's Pacific Missile Range Facility in Hawaii. The Helios Prototype flying wing is shown over the Pacific Ocean during its first test flight on solar power from the U.S. The Helios Prototype flying wing is shown moments after takeoff, beginning its first test flight on solar power from the U.S. The Helios Prototype aircraft at approximately 10,000 feet flying above cloud cover northwest of Kauai, Hawaii. The Helios Prototype aircraft in a northerly climb over Niihau Island, Hawaii, at about 8,000 feet above sea level.

NASA's Helios Prototype aircraft taking off from the Pacific Missile Range Facility, Kauai, Hawaii, for the record flight The solar-powered Helios Prototype flying wing frames two modified F-15 research aircraft in a hangar at NASA's Dryden Flight Research Center The Helios Prototype flying wing stretches almost the full length of the 300-foot-long hangar at NASA's Dryden Flight Research Center Technicians for AeroVironment, Inc., jack up a pressure tank to the wing of the Helios Prototype solar-powered flying wing. Helios is now equipped with an experimental fuel cell system to allow nighttime flight.Īerovironment technicians line up attachments as a fuel cell electrical system is installed on the Helios Prototype solar powered flying wing. The solar-electric Helios Prototype flying wing bisects the volcanic atoll of Lehua off the coast of Kaua'i, Hawaii, during a checkout flight on June 7, 2003. NASA's Helios Prototype electrically powered flying wing began a checkout flight June 7 from the Navy's Pacific Missile Range Facility on the Hawaiian island of Kauai.Įquipped with an experimental fuel cell system to allow night time flight, the solar-electric Helios Prototype flying wing soars over the blue Pacific off the Hawaiian island of Kauai. Prior to its loss in an in-flight mishap in June 2003, the Helios Prototype set a world altitude record for propeller-driven aircraft of almost 97,000 feet.ĭFRC Press Releases 03-27, 03-29, 03-31, 03-32, 03-33, UpdatesĮquipped with an experimental fuel cell system to power the aircraft at night, the solar-electric Helios Prototype is shown during a checkout flight prior to its long-endurance flight demonstration in the summer of 2003. The Helios Prototype solar-electric flying wing was one of several remotely piloted aircraft, also known as uninhabited aerial vehicles or UAVs, that were developed as technology demonstrators under the now-concluded Environmental Research Aircraft and Sensor Technology (ERAST) project.
