Belbin Cycleplane

A 1912 pedal-powered monoplane built by Wandsworth blacksmith H. W. G. Belbin, using an old bicycle frame and wings made of bamboo and oiled canvas. It was driven on the ground by the rear wheel, which also drove the tractor propeller. The machine was “constructed under difficulties, and in spare time, the family kitchen having been utilized as a workshop”, and it bore “unmistakable evidence of the trade of its builder in the form of many fancy bits of smithing”.

Bazin Aéroplane à ailes battantes

Albert Bazin built a series of gliders from 1904 up to 1907. In 1907 he built this ornithopter with a 12 hp three-cylinder engine. It had no rudder, since the machine “was built to fly straight forward, the shortest distance between one point and another being the straight line”. The area of the different wings could be extended and decreased, thereby achieving lateral control. It was apparently tested suspended from a wire.

Baumgarten-Wölfert Weißen Adler Dreigondelluftschiff

The “Weißen Adler” (“White Eagle”) airship was built in Dresden by Georg Baumgarten in 1879. Baumgarten became acquainted with the wealthy Leipzig bookseller Dr. Friedrich Hermann Wölfert, who liked him for his experiments in airships. Together they built the 26 meters long airship, which had three gondolas and had propellers driven by hand cranks. Their first airship, the “Dreigondelluftschiff” rose on 31 January 1880, the first time in Leipzig-Plagwitz. However, the flight ended with an accident, but with no injuries, but the airship was destroyed.

Barnard Centennial Airship

Professor Arthur W. Barnard, Director of Physical Training for the YMCA of Nashville, built this airship, which measured 18 feet in diameter and 46 feet in length. It was filled with hydrogen and used a propeller of 8 feet diameter. Barnard pedalled his Centennial Airship in Nashville at the Tennessee Centennial Exhibition of 1897. He went a distance of some 20 miles with the help of a strong wind, but on the return the spar broke off one of the propellers and he landed twelve miles short of returning to the Exhibition grounds. During another ascension the balloon split at the height of a half mile. It descended with great rapidity, but when some distance from the ground it formed a kind of a parachute and the professor landed safely near the exposition grounds. He received a shaking up, but was not injured.

Baldwin Aerial Rowboat

Baldwin, known for his balloons and parachutes and, in 1910, his Red Devil airplanes, was the first to debut an aerial rowboat. Baldwin had already built the California Arrow, the first U.S. airship to make a controlled circular flight, when he won a contract with a Los Angeles amusement park to exhibit a dirigible that could be rowed through the air like a boat. In 1905, Baldwin came up with a 38-foot-long hydrogen-filled gas bag with a kayak-shaped frame underneath. In lieu of an engine were bamboo oars with paddles made of silk. A canvas bag filled with sand maintained neutral buoyancy.

Baldwin’s non-rigid dirigible could do about 4 mph on a calm day, but even a slight headwind would stymie it. Because Baldwin was too heavy to pilot the craft, he hired 23-year-old L. Guy Mecklem. On the craft’s maiden voyage, Mecklem became stranded 2,000 feet above the crowd with a broken oar and a malfunctioning safety valve on the bag. “The sun got hotter and the hydrogen expanded and nothing I could do…would stop it” from rising, he recalled. After the sun set, Mecklem was able to land in an orange grove.

The next day, Baldwin strung a 300-foot-long wire between two poles and attached a guideline to the aerial rowboat so it could slide along the wire. Mecklem spent the next two weeks practicing how to row back and forth.

“We could put on a pretty good show,” Mecklem recalled in his unpublished autobiography. Ascending a few hundred feet, he bombed his audience with bags of peanuts. He’d also throw his handkerchief overboard and paddle down to retrieve it. His favorite stunt was aiming the tip of the gas bag at a girl in the grandstand and rowing away at the last second as she tried to dodge it.

Alva L. Reynolds challenged Baldwin to an airship race in his own version. When Baldwin’s pilot, the balloonist Roy Knabenshue, asked for $20,000 in expense money, Reynolds said Knabenshue was “afraid to race.”

Baldwin’s aerial rowboat proved a remunerative attraction, though a short-lived one: One night its hydrogen inexplicably ignited, destroying the craft.

AeroVelo Atlas

The American Helicopter Society issued a a prize of $10,000 for the Igor I Sikorsky Human Powered Helicopter Competition in 1980. By May 2009 the prize was $250,000. The requirement was to lift off to a height of 3m/9.8ft and hover over a 10sq.m/107.6 sq.ft ‘box’ for one minute using only human power. More than 20 teams tried and failed.

The AeroVelo team 9the name derived from ‘aerodynamic’ and Velo, French for bicycle) was led by pilot and chief engineer Dr. Todd Reichert and co-chief engineer Cameron Robertson, and made up of students at the University of Toronto.

The Atlas four rotors each span nearly 21.3m/70 ft. The airframe is of very light carbonfibre tubes and polymer weighing only 52kg/115lb, with a highly modified bicycle frame pedalled by the pilot.

The Atlas received many incremental improvements during 18 months and on 13 June 2013 Altas flew for 64.11 seconds, reached a peak altitude of 3.3m/10.8ft, and drifted off-centre a maximum of 9.8m/32.2ft.

The American Helicopter Society declared the Toronto, Canada-based AeroVelo Atlas team the winners.
