History Of Human-powered Aircraft
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 (aeronautics), 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 smaller gear, which turns a vertical shaft that either turns a set of bevel gears, which turns another, horizontal shaft that ultimately turns a propeller, or in the case of earlier prototypes, an ornithopter mechanism. Often, a hybrid system is used; where during a certain amount of time pedaling, it would charge a battery, which would, at the push of a button, power an electric motor that is connected to the same horizontal shaft as the propeller. Human-powered aircraft have been successfully flown over considerable distances. However, they are still primarily c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dumbo-Mercury
__NOTOC__ The Weybridge Man Powered Aircraft (also known as ''Dumbo'' and later ''Mercury'') is a British single-seat man-powered aircraft built and flown by members of the Weybridge Man Powered Aircraft Group. Development The Weybridge Man Powered Aircraft Group was formed in late 1967 with members drawn from the British Aircraft Corporation factory and the local chapter of the Royal Aeronautical Society. Construction started in 1968 and the aircraft was assembled at Wisley and flown for the first time from Weybridge on 18 September 1971. The Weybridge MPA (which was named ''Dumbo'') was flown by Christopher Lovell for a distance of 46 metres with a height reached of 3 ft (0.9m). Only two flights were made at Weybridge and the aircraft was passed to another group at RAF Cranwell who renamed it ''Mercury''. Design The aircraft is a low-wing cantilever monoplane with a fuselage made from aluminium Aluminium (or aluminum in North American English) is a chemical ...

Da Vinci III
A human-powered helicopter (HPH) is a helicopter powered solely by one or more humans carried on board. As in other human-powered aircraft, the power is usually generated by pedalling. It remains a considerable engineering challenge to obtain both the power-to-weight ratio and rotor efficiency required to sustain a helicopter in flight. On 13 June 2013, the AeroVelo Atlas was the first to complete a flight that lasted 64 seconds and reached an altitude of 3.3 meters or 10.82 feet, thus winning the American Helicopter Society (AHS) International's Igor I. Sikorsky Human Powered Helicopter Competition. The AHS Sikorsky Prize The American Helicopter Society (AHS) International's Igor I. Sikorsky Human Powered Helicopter Competition was a competition to achieve the first human-powered helicopter flight to reach an altitude of 3 m (10 ft) during a flight lasting at least 60 seconds, while remaining within a 10 m (32.8 ft) x 10 m (32.8 ft) squar ...

California Polytechnic State University
California Polytechnic State University, San Luis Obispo (Cal Poly San Luis Obispo or Cal Poly) is a public university in San Luis Obispo County, California, United States, - Cites the location of the university and shows that the university is outside of the San Luis Obispo city limits. Even though the postal address says "San Luis Obispo, CA", it is not in the city limitsThe City of Houston stated "The U.S. Postal Service establishes ZIP codes and mailing addresses in order to maximize the efficiency of their system, not to recognize jurisdictional boundaries." outside of the city limits of San Luis Obispo. Founded in 1901, it is the oldest of Cal Poly (other), three polytechnic universities within the California State University system. Cal Poly emphasizes a "learn by doing" philosophy, integrating hands-on, practical experiences into its curriculum. As of fall 2022, Cal Poly had approximately 21,000 undergraduate and 800 graduate students. Cal Poly is well-regard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DaSH PA
The DaSH PAdead simple human powered airplaneis a project led by Alec Proudfoot to build and fly a human-powered aircraft. The project's first flight on December 5, 2015, at Half Moon Bay Airport, was piloted by Proudfoot during which the aircraft flew . Subsequent flight trials in February, June, and November 2016, have also been successful. The second November 5 flight, piloted by Craig Robinson, covered and lasted four minutes. The longest flight yet occurred on November 18, 2017, lasting 5 minutes and 20 seconds, covering 1.92 km. Project history Proudfoot started the DaSH PA project in late 2010 as a "for-fun, afterhours project to build a human powered airplane". The original design goals were a weight of , and wingspan of . It was designed to fly at . In October 2015, the team conducted wing load testing at the Hiller Aviation Museum in San Carlos, California. Over its history, the DaSH PA team has included hundreds of volunteers, and as of November 2017, n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cranfield Vertigo
The ''Vertigo'' was a human-powered helicopter designed and built in the 1980s by Andrew Cranfield, an engineer with Westland Helicopters. Development In 1980, Cranfield was a graduate apprentice with Westland Helicopters, when he was prompted by the American Helicopter Society offering the Sikorsky Prize for human-powered helicopters, to develop a design for that competition. The design Cranfield developed was a coaxial helicopter comprising two identical two-bladed rotors, each having a diameter of and blades with a constant chord. The lower rotor was set at 6° dihedral, and the higher rotor at 9° dihedral. In order to take advantage offered by ground effect, the rotors were set as low to the ground, and as closely together, as could be practically achieved, with the fuselage and pilot being located above the rotor assembly. The rotors were constructed of carbon fibre, styrofoam and Mylar. The blades were fixed, with the pitch and coning built into their design. Fli ...
