Hartman Ikarus
__NOTOC__ The ''Ikarus'' was a human-powered ornithopter, designed by the sculptor and designer Emiel Hartman in the late 1950s. Development The ornithopter was a high-wing monoplane, with the pilot seated in a recumbent position. Its construction followed conventional glider practice of the time. The fuselage had a bulkhead construction, covered in thin plywood. The wings featured a torsion-box spar and leading edge arrangement, and were also made from thin plywood. A series of 30 'feathers', covered in madapollam cotton were attached aft of the spar, and were able to individually bend and twist as the wings were flapped. The wings could be flapped through an arc of 30° dihedral to 10° anhedral, via a parallelogram structure which the pilot could operate using leg and arm power, with a rowing-like action. Bungee cords were integrated into the drive mechanism, to absorb and release energy as needed. It was expected that the wings would flap at 30 beats per minute. T ...

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-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 constructed as engineer ...

HMPAC Puffin
The HMPAC Puffin was a British man-powered aircraft designed by a team headed by John Wimpenny, an aerodynamicist at the de Havilland Aircraft Company. It was built by the Hatfield Man Powered Aircraft Club (HMPAC) on the company's premises in Hatfield, Hertfordshire. On 2 May 1962, Wimpenny, aged 39, piloted the Puffin at the Hatfield Aerodrome, pedalling to power the propeller, achieving a flight distance of , a world record which was to stand for ten years. The Puffin had a wingspan of . Puffin II An improved version of the Puffin was developed and built in 1965 as the HMPAC Puffin II. First flown on 27 August 1965, the Puffin II utilized the transmission components of the Puffin I in a completely new airframe. After it had been damaged, the Puffin II airframe was given to Liverpool University, who used it to build the Liverpuffin.

Ornithopters
An ornithopter (from Greek ''ornis, ornith-'' 'bird' and ''pteron'' 'wing') is an aircraft that flies by flapping its wings. Designers sought to imitate the flapping-wing flight of birds, bats, and insects. Though machines may differ in form, they are usually built on the same scale as flying animals. Larger, crewed ornithopters have also been built and some have been successful. Crewed ornithopters are generally powered either by engines or by the pilot. Early history Some early crude flight attempts may have been intended to achieve flapping-wing flight, but probably only a glide was actually achieved. They include the purported flights of the 11th-century Catholic monk Eilmer of Malmesbury (recorded in the 12th century) and the 9th-century poet Abbas Ibn Firnas (recorded in the 17th century). Roger Bacon, writing in 1260, was also among the first to consider a technological means of flight. In 1485, Leonardo da Vinci began to study the flight of birds. He grasped that humans ar ...

Aircraft First Flown In 1959
An aircraft ( aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called '' aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different cr ...

1950s British Experimental Aircraft
Year 195 (Roman numerals, CXCV) was a common year starting on Wednesday of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

MacCready Gossamer Condor
The MacCready ''Gossamer Condor'' was the first human-powered aircraft capable of controlled and sustained flight; as such, it won the Kremer prize in 1977. Its design was led by Paul MacCready of AeroVironment, Inc. Design and development 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 end. Early attempts to build human-powered aircraft had focused on wooden designs, which proved too heavy. Very early attempts – notably the ' and ''Pedaliante'' – used catapult launches. In 1961, Southampton University's Man Powered Aircraft SUMPAC took to the air at Lasham Airfield on 9 November, piloted by Derek Piggott, achieving a maximum flight of .

MacCready Gossamer Albatross
The ''Gossamer Albatross'' is a human-powered aircraft built by American aeronautical engineer Dr Paul B MacCready's company AeroVironment. On June 12, 1979, it completed a successful crossing of the English Channel to win the second Kremer prize worth £100,000 (). Design and development 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 -long figure-eight course. The second Kremer challenge was then announced as a flight across the English Channel recalling Louis Blériot's crossing of 1909. The aircraft is of " canard" configuration, using a large horizontal stabilizer forward of the wing in a manner similar to the Wright brothers' successful ''Wright Flyer'' aircraft and powered using pedals to drive a ...

Malliga 1
The Malliga 1 human powered aircraft was the project of Horst Josef Malliga. It is thought that it was the first successful Continental European human-powered aircraft. Design work began in August 1966, with the first flight taking place in September 1967. The aircraft was a low-wing monoplane, with a pod and boom configuration. The pilot sat in a recumbent position, and powered a two bladed pusher propeller, located behind a streamlined nacelle. Twin booms supported twin fins, with an all-flying tailplane located between them. Constructed from aluminium tubing and polystyrene, with plastic film covering. The Malliga 1 had a constant-chord wingplan, and spanned 20.00 m (65 ft 7in). As originally designed, the tailfins did not incorporate rudders, and directional control was made via two fins located outboard and underneath the wing. Lateral control was obtained by wingtip ailerons. With this configuration, and under human-power alone, flights of up to 150 m (487 ...

HPA Toucan
__NOTOC__ The HPA ''Toucan'' is a British two-seat human-powered aircraft built and flown by members of the Hertfordshire Pedal Aeronauts and was the first two-person human-powered aircraft to fly. Development The Hertfordshire Pedal Aeronauts was formed in 1965, mainly from the staff of Handley Page Limited, to design and build a human-powered aircraft and to compete for the Kremer Prize. The aircraft, unique in being powered by two persons, was designed by Martyn Pressnell. Pressnell was at the time a stress engineer with Handley Page. Partly funded by a grant from the Royal Aeronautical Society construction began in 1967 and was completed in 1972. Following taxying trials at Radlett Aerodrome on 16 June 1972 when brief hops were made, the aircraft made its first flight on 23 December 1972. Flown by Bryan Bowen with Derek May as crewman the longest flight was , the Toucan flew again on 3 July 1973 for and achieved a height of . Design The ''Toucan'' is a mid-wing cantileve ...

Goodhart Newbury Manflier
The Goodhart ''Newbury Manflier'' was a two-place human-powered aircraft designed by Nicholas Goodhart. Its most notable feature was that the two pilots were placed in separate fuselages, spaced 70 ft apart. Design and development The genesis of the aircraft was detailed in a paper presented at a 1974 conference hosted by the Man-Powered Aircraft Group of the Royal Aeronautical Society, and later published in its Journal. In the paper, after initially describing the requirements for an aircraft to win the Kremer Prize then on offer, Goodhart proposed a two-person monoplane, with a 100 ft wingspan, with each pilot being located in separate nacelles at the wingtips. This configuration would reduce the bending moments on the wing spar, and hence the overall weight. Turning radius would be in the order of 1,000 ft, and with each pilot generating 0.20 hp (or 140 watts) to maintain flight. The design evolved, so that when construction of the Newbury Manflier co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
