A human-powered aircraft (HPA) is an aircraft belonging to the class of vehicles known as human-powered transport.. As its name suggests, HPAs have the pilot not only steer, but power the aircraft (usually propeller-driven) by means of a system similar to a bicycle or tricycle: a pair of pedals, moved by the pilot's feet that turns a gear, which then moves a bicycle chain, which then rotates a ...
The Kremer Prize had been set up in 1959 by Henry Kremer, a British industrialist, and offered £50,000 in prize money to the first group that could fly a human-powered aircraft over a figure-eight course covering a total of one mile (1.6 kilometers). The course also included a ten-foot pole that the aircraft had to fly over at the start and at ...
The aircraft was designed and built by a team led by Paul B. MacCready, a noted American aeronautics engineer, designer, and world soaring champion. Gossamer Albatross was his second human-powered aircraft, the first being the Gossamer Condor, which had won the first Kremer prize on August 23, 1977, by completing a 1-mile (1.6 km)-long figure-eight course.
He was the founder (in 1971) and Chairman of AeroVironment Inc., a public company (AVAV) that develops unmanned surveillance aircraft and advanced power systems. AV flew a prototype of the first airplane to be powered by hydrogen fuel cells, the Global Observer. [20] MacCready died on August 28, 2007, from metastatic melanoma.
The Olympian ZB-1 was the first human-powered aircraft to have flown in the United States. [1] [2] [3] It was designed, built, and flown by Joseph A. Zinno, of North Providence, Rhode Island. Zinno had previously been a USAF Lieutenant Colonel, and undertook the challenge of making a human-powered aircraft as a post-retirement project. [3] [4]
Most powered model-aircraft, including electric, internal-combustion, and rubber-band powered models, generate thrust by spinning an airscrew. The propeller is the most commonly used device. Propellers generate thrust due to lift generated by the wing-like sections of the blades, which forces air backward.
