Comet 130hp
The Comet 7-cylinder radials were a family of air-cooled radial engines, designed and built by the Comet Engine Corporation at Madison, Wisconsin from around 1927. Design and development Comet designed the 7-cylinder radial series to take advantage of the boom in private aviation in the late 1920s; intending to replace the large number of relatively unreliable wartime surplus engines that flooded the market in the early 1920s. First produced by the Aircraft Engine Corporation of Oakland, California, new interests acquired the California company and the Comet Engine Corporation was formed under the sponsorship of Air Investors Inc., the Crocker First Company of San Francisco and the Gisholt Machine Company. Production transferred to workshops adjacent to the Gisholt Machine Company in Madison, which acted as production supervisor. The Comet radial was fairly standard with steel finned cylinders, cast light alloy cylinder heads and two valves per head. The valves are operated by ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maximum Safety M-3
In mathematical analysis, the maximum and minimum of a function are, respectively, the greatest and least value taken by the function. Known generically as extremum, they may be defined either within a given range (the ''local'' or ''relative'' extrema) or on the entire domain (the ''global'' or ''absolute'' extrema) of a function. Pierre de Fermat was one of the first mathematicians to propose a general technique, adequality, for finding the maxima and minima of functions. As defined in set theory, the maximum and minimum of a set are the greatest and least elements in the set, respectively. Unbounded infinite sets, such as the set of real numbers, have no minimum or maximum. In statistics, the corresponding concept is the sample maximum and minimum. Definition A real-valued function ''f'' defined on a domain ''X'' has a global (or absolute) maximum point at ''x''∗, if for all ''x'' in ''X''. Similarly, the function has a global (or absolute) minimum point at ''x''∗, if ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Travel Air 4-U
The Travel Air 2000 is an open-cockpit biplane aircraft produced in the United States in the late 1920s by the Travel Air Manufacturing Company. During the period from 1924–1929, Travel Air produced more aircraft than any other American manufacturer, including over 1,000 biplanes. While an exact number is almost impossible to ascertain due to the number of conversions and rebuilds, some estimates for Travel Air as a whole range from 1,200 to nearly 2,000 aircraft.Wilkinson, 28 February 2014, pp.? Design and development The Travel Air Model A was engineered chiefly by Lloyd Stearman, with input from Travel Air co-founders Walter Beech, Clyde Cessna, and Bill Snook and could trace its ancestry back to the Swallow New Swallow biplane. The Travel Air, however, replaced the New Swallow's wooden fuselage structure with welded steel tubes. An interim design, the Winstead Special, was developed by the Winstead brothers from a metal fuselage frame developed at Swallow by Stearm ...

Towle WC Amphibion
The Towle WC, or Towle TA-1, was a custom built aircraft for a 1929 round-the world flight. Design and development Thomas Towle was an engineer who had been involved with many early aircraft designs. Having just co-designed the Eastman-E2 Sea Rover, Towle was commissioned by Henry McCarroll to promote Detroit's aviation production capabilities. The WC was a flying boat with an aluminum hull. The strut braced parasol wing was fabric covered. Operational history The prototype WC flew as far as Brazil Brazil, officially the Federative Republic of Brazil, is the largest country in South America. It is the world's List of countries and dependencies by area, fifth-largest country by area and the List of countries and dependencies by population ... before engine reliability issues forced the cancellation of the round-the-world flight attempt.

Timm K-100 Collegiate
The Timm Collegiate was a series of American-built two-seat light aircraft of the late 1920s. Design and development Otto Timm founded the O.W. Timm Aircraft Corp in 1922 with its base at Glendale, California. The firm changed its name to the Timm Airplane Co in 1928. During 1928 Timm designed the Collegiate series of parasol-winged two-seat light aircraft fitted with fixed tailwheel undercarriage. The six examples built between 1928 and 1930 were powered by a variety of engines of between and During their lives, several were re-fitted with different powerplants."Timm aircraft." ''Aerofiles.'' Retrieved: March 29, 2012. Operational history During their operational lives, several of the six Collegiates were fitted with replacement powerplants, giving rise to new designation numbers.
