Dymaxion car

The Dymaxion car was designed by American inventor Buckminster Fuller during the Great Depression and featured prominently at Chicago's 1933/1934 World's Fair. Fuller built three experimental prototypes with naval architect Starling Burgess – using donated money as well as a family inheritance – to explore not an automobile per se, but the 'ground-taxiing phase' of a vehicle that might one day be designed to fly, land and drive – an "Omni-Medium Transport". Fuller associated the word Dymaxion with much of his work, a portmanteau of the words dynamic, maximum, and tension, to summarize his goal to do more with less. It could hold 11 passengers, reach speeds of up to 90 mph (140 km/h), and had a fuel economy of 30 mpg‑US (8 L/100 km; 36 mpg‑imp). The Dymaxion's aerodynamic bodywork was designed for increased fuel efficiency and top speed, and its platform featured a lightweight hinged chassis, rear-mounted V8 engine, front-wheel drive (a rare RF layout), and three wheels. With steering via its third wheel at the rear (capable of 90° steering lock), the vehicle could steer itself in a tight circle, often causing a sensation. Fuller noted severe limitations in its handling, especially at high speed or in high wind, due to its rear-wheel steering (highly unsuitable for anything but low speeds) and the limited understanding of the effects of lift and turbulence on automobile bodies in that era – allowing only trained staff to drive the car and saying it "was an invention that could not be made available to the general public without considerable improvements." Shortly after its launch, a prototype crashed and killed the Dymaxion's driver. Despite courting publicity and the interest of auto manufacturers, Fuller used his inheritance to finish the second and third prototypes, selling all three, dissolving Dymaxion Corporation and reiterating that the Dymaxion was never intended as a commercial venture. One of the three original prototypes survives, and two semi-faithful replicas have recently been constructed. The Dymaxion was included in the 2009 book Fifty Cars That Changed The World and was the subject of the 2012 documentary The Last Dymaxion. In 2008, The New York Times said Fuller "saw the Dymaxion, as he saw much of the world, as a kind of provisional prototype, a mere sketch, of the glorious, eventual future."

History

Fuller would ultimately go on to fully develop his Comprehensive Anticipatory Design Science, his theory of using all technology on behalf of all people as soon as possible, but by this point it was "his job, Fuller decided, to identify a problem, develop a way to solve it, and wait – perhaps as long as twenty-five years – for public awareness to catch up." In 1930, Fuller had purchased an architectural magazine, T-Square, which he ultimately renamed Shelter. Fuller edited the magazine anonymously for two years, and in 1928 published sketches of his land-air-water vehicle, called a 4D Transport. 4D stood for Four Dimensional, a term used in physics and mathematics, referring to length, width, depth and time. Regarding the 4D transport, author Lloyd S. Sieden, wrote in his 2000 book Bucky Fuller's Universe: With such a vehicle at our disposal, [Fuller] felt that human travel, like that of birds, would no longer be confined to airports, roads, and other bureaucratic boundaries, and that autonomous free-thinking human beings could live and prosper wherever they chose. To his daughter, Allegra, he described the Dymaxion as: A "zoomobile", explaining that it could hop off the road at will, fly about, then, as deftly as a bird, settle back into a place in traffic. Fuller was offered $5,000 (2023: $119,500) from wealthy former stock trader and socialite Philip (variously reported as Phillip) Pearson and his wife Temple Pearson (niece of Isadora Duncan) of Philadelphia. Pearson was a stock broker and had presciently sold short a large quantity of stock before the Great Depression, becoming instantly wealthy. Pearson had known of Fuller's studies, had more wealth than he needed, and felt he could put Fuller and others to work in a way that would also do something to alleviat

Design

Because Fuller was aiming for what he called Omni Medium Transport, a vehicle that could go anywhere, the Dymaxion would ultimately have "wheels for ground travel and jet stilts for instant takeoff and flight." Jet stilts were Fuller's placeholder idea for a future technology that could provide compact, concentrated lift — twenty years before the commercial availability of jets. Estimating that designing a land–sea–air vehicle was then financially and technically out of reach, Fuller focused on the most dangerous and challenging mode of such vehicle: landing and taxiing on hard ground. Fuller favored front-wheel drive, studying the way a wheelbarrow could more effectively pull its load rather than pitch forward when pushing a load. He began studies of the relationships between vehicles (cars, trucks – and also birds and fish) with the media in which they operated (fluid dynamics) – as well as steering mechanisms in nature, especially the rear "single fin" steering of birds and fish. Burgess, inventor of the first delta-wing aircraft, was invaluable to the project – but skeptical the vehicle would ever fly. Fuller theorized that getting a long, aerodynamic 'plane' fuselage – which was also inclined to have trailing, rear steering – to land safely and not immediately turn into the wind, would be a major challenge. The vehicle would inherently exhibit something he called "ground-loopiness," and chose to focus his energy there. Although it was never intended as such, Fuller anticipated the public would instinctively call such a vehicle an automobile, and when licensing to drive the vehicle on Connecticut roads, acquiesced and applied for an automobile registration. Fuller had worked with sculptor Isamu Noguchi to create plaster wind tunnel models of the Dymaxion to help det

Prototypes One, Two and Three

Prototype One, at 20 feet (6.1 m) long, was built on a hinged two-frame chassis constructed of lightweight chromoly steel with aircraft-type dished lightening holes – and powered by a Ford V8 engine producing 85 brake horsepower (63 kW; 86 PS) in a rear-engine, front-wheel-drive layout. The front axle was a re-purposed and inverted (the flipped axle must be inverted to prevent the pinion gears from running the wrong way) rear axle from a contemporary Ford roadster. Tires were provided by Goodyear. The suspension used leaf springs "turned sideways" (transverse leaf springs) and bodywork featured sheet aluminum over an ash wood frame, with a roof partially constructed of snap-on painted canvas. Original blueprints indicate seating for four, including the driver. Fuller said he had achieved fuel economy of 36 mpg (7.8L/100 km) and to have reached a speed of 206 km/h (128 mph). Jeff Lane, founder of the Lane Motor Museum and owner of a Dymaxion Car replica, estimates the true top speed at 80–85 mph (129–137 km/h), further limited in practice by engine performance and poor handling; his replica only achieved less than half the fuel economy claimed by Fuller, as well. Prototypes Two and Three featured developmental improvements including a lighter three-frame chassis central periscope providing rearward vision, larger side windows, recessed headlights and a roof-mounted stabilizer with rear-facing exhaust outlet. Videos: In contemporary videos (see External links, below), Fuller is seen driving the vehicle at high speed. Another shows Fuller showing off his speeding ticket, demonstrating its ability to turn "on itself", easily parallel parking in a space only six inches longer than the car, remarking that he averaged over 22 mpg (up to 30 mpg), and commenting on its stability

Later prototype history

Prototype One was badly damaged in the noted car crash at the time of the 1933 Chicago Century of Progress fair. The car was repaired and sold to the director of the automotive division of the U.S. Bureau of Standards (BoS), only to be subsequently destroyed in a fire at the Washington D.C. garage of the BoS. Prototype Two survives in the Harrah Collection of the National Automobile Museum in Reno, Nevada. Prototype Two was initially purchased by Alfred Williams, manager of the Gulf Refining Company and driven cross country in a nationwide advertising promotion of aircraft fuel. In a contemporary video (see External links, below), Fuller notes that good friend Amelia Earhart asked that the Dymaxion be her official car for the celebration of her receiving the National Gold Medal from National Geographic. Dymaxion Prototype Two was driven to Washington and garnered considerable publicity. Prototype Three changed hands many times but was lost, presumed scrapped, in the 1950s. Once owned by Leopold Stokowski, it was estimated to have been driven 300,000 miles. In 1934, Noguchi drove a completed Dymaxion on an extended road trip through Connecticut with Clare Boothe Luce and Dorothy Hale, stopping to see Thornton Wilder in Hamden, Connecticut, before driving to Hartford for the out-of-town opening of Gertrude Stein's and Virgil Thomson's Four Saints in Three Acts. One of the prototypes was driven extensively in a campaign to raise funds in support of the Allies in WW II.

Handling limitations

Fuller and Burgess realized early that the Dymaxion concept would present considerable challenges. As anticipated, and in line with the purpose of the exploration, maneuvering in high winds proved problematic, with the vehicle having a strong tendency to turn into the wind. Steering difficulty and lift at the rear of the vehicle were also observed. Fuller realized the Dymaxion "was an invention that could not be made available to the general public without considerable improvements," and instituted a program of constant refinement and improvement to the platform. Because of its limitations, Fuller and Burgess limited driving to a list of trained drivers and restricted use in high winds or inclement weather.

Speed record

Soon after launching Prototype One, Fuller was invited to exhibit the Dymaxion at a Bronx race track, beating the track record by 50% and drawing attention because it did not slide or drift across the track like the other race cars.
