Travel Air 2000, 3000 And 4000
The Travel Air 2000/3000/4000 (originally, the Model A, Model B and Model BH were 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 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 a welded steel tube. An interim design, the Winstead Special, was developed by ...

Welded
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal). In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that, based on weld configuration (butt, full penetration, fillet, etc.), can be stronger than the base material. Pressure may also be used in conjunction with heat or by itself to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized. Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron beam, friction Friction is the force resisting ...

Air Cargo
Air cargo is any property carried or to be carried in an aircraft. Air cargo comprises air freight, air express and airmail. Aircraft types Different cargo can be transported by passenger, cargo or combi aircraft: * Passenger aircraft use the spare volume in the airplane's baggage hold (the "belly") that is not being used for passenger luggage—a common practice used by passenger airlines, who additionally transport cargo on scheduled passenger flights. Cargo can also be transported in the passenger cabin as hand-carry by an “on-board courier”. This practice can often be used to cross subsidise loss-making passenger routes that would otherwise be uneconomical to operate. A passenger aircraft can also be used as a preighter in which the entire passenger cabin is temporarily dedicated to carrying freight. * Cargo aircraft are dedicated for the job—they carry freight on the main deck and in the belly by means of nose-loading or side loading. * Combi aircraft carry c ...

Air Charter
Air charter is the business of renting an entire aircraft (i.e., chartering) as opposed to individual aircraft seats (i.e., purchasing a ticket through a traditional airline). Regulation Charter – also called air taxi or ad hoc – flights require certification from the associated country's civil aviation authority. The regulations are differentiated from typical commercial/passenger service by offering a non-scheduled service. Analogous regulations generally also apply to air ambulance and cargo operators, which are often also ad hoc for-hire services. United States In the U.S. these flights are regulated under FAA Part 135. There are some cases where a charter operator can sell scheduled flights, but only in limited quantities. As of 2021, the FAA had made it a priority to crack down on unauthorised charter flights, according to industry experts. Types of service There are several business models which offer air charter services from the traditional charter operator to ...

Air Taxi
An air taxi is a small commercial aircraft that makes short flights on demand. In 2001 air taxi operations were promoted in the United States by a NASA and aerospace industry study on the potential Small Aircraft Transportation System (SATS) and the rise of light-jet aircraft manufacturing. Since 2016, air taxis have reemerged as part of the burgeoning field of eVTOL. Regulation In Canada, air taxi operations are regulated by Transport Canada under Canadian Aviation Regulation 703. The Canadian definition of air taxi includes all commercial single-engined aircraft, multi-engined helicopters flown by visual flight rules by one pilot and all multi-engined, non-turbo-jet aircraft, with a maximum take-off weight or less and nine or fewer passenger seats, that are used to transport people or goods or for sightseeing. In the US, air taxi and air charter operations are governed by 14 CFR Part 135 and 14 CFR part 298 of the Federal Aviation Regulations (FAR).

Air Racing
Air racing is a type of motorsport that involves airplanes or other types of aircraft that compete over a fixed course, with the winner either returning the shortest time, the one to complete it with the most points, or to come closest to a previously estimated time. History The first 'heavier-than-air' air race was held on 23 May 1909 - the Prix de Lagatinerie, at the Port-Aviation airport south of Paris, France. Four pilots entered the race, two started, but nobody completed the full race distance; though this was not unexpected, as the rules specified that whoever travelled furthest would be the winner if no-one completed the race. Léon Delagrange, who covered slightly more than half of the ten laps was declared the winner. Some other minor events were held before the '' Grande Semaine d'Aviation de la Champagne'' in 22–29 August 1909 at Reims, France. This was the first major international flying event, drawing the most important aircraft makers and pilots of the era ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waco Aircraft Company
The Waco Aircraft Company (WACO) was an aircraft manufacturer located in Troy, Ohio, United States. Between 1920 and 1947, the company produced a wide range of civilian biplanes. The company initially started under the name Weaver Aircraft Company of Ohio but changed its name to the Waco Aircraft Company in 1928/29. Company name WACO (referring to the aircraft) is usually pronounced "wah-co" (the first syllable pronounced as in "water"), not "way-co" like Waco, Texas, whose name is entirely unrelated. Several companies operated under the Waco name, with the first company being the Weaver Aircraft Company, a firm founded by George E. Weaver, Clayton Bruckner, and Elwood Junkin in 1920 in Lorain and Medina, Ohio after they had already been collaborating for several years. In the spring of 1923 this became the Advance Aircraft Company in Troy, Ohio, after the departure of Weaver. In 1929, it was changed from Advance Aircraft Company to Waco Aircraft Company. The firm is ofte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtiss JN-4 Jenny
The Curtiss JN "Jenny" was a series of biplanes built by the Curtiss Aeroplane Company of Hammondsport, New York, later the Curtiss Aeroplane and Motor Company. Although the Curtiss JN series was originally produced as a training aircraft for the US Army, the "Jenny" (the common nickname derived from "JN") continued after World War I as a civil aircraft, as it became the "backbone of American postWorld War I, war [civil] aviation". Thousands of surplus Jennys were sold at bargain prices to private owners in the years after the war and became central to the barnstorming era that helped awaken the US to civil aviation through much of the 1920s. Design and development Curtiss combined the best features of the Curtiss Model J, model J and Curtiss Model N, model N Training aircraft, trainers, built for the United States Army, US Army and United States Navy, US Navy, and began producing the JN or "Jenny" series of aircraft in 1915. Curtiss built only a limited number of the JN-1 and J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Aircraft
A steam-powered aircraft is an aircraft propelled by a steam engine. Steam power was used during the 19th century, but fell into disuse with the arrival of the more practical internal combustion engine at the beginning of the pioneer era. Steam power is distinct from its use as a lifting gas in thermal airships and early balloons. History * 1842: The Aerial Steam Carriage of William Samuel Henson and John Stringfellow was patented, but was never successful, although a steam-powered model was flown in 1848. * 1852: Henri Giffard flew a 3-horsepower (2 kW) steam-powered dirigible over Paris; it was the first powered aircraft. * 1861 Gustave Ponton d'Amécourt made a small steam-powered craft, coining the name helicopter. * 1874: Félix du Temple flew a steam-powered aluminium monoplane off a downhill run. While it did not achieve level flight, it was the first manned heavier-than-air powered flight. * 1877: Enrico Forlanini built and flew a model steam-powered helicopter ...

Compound Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

Doble Steam Car
The Doble steam car was an American steam car maker from 1909 to 1931. Its latter models of steam car, with fast-firing boiler and electric start, were considered the pinnacle of steam car development. The term "Doble steam car" comprises any of several makes of steam-powered automobile in the early 20th century, including Doble Detroit, Doble Steam Car, and Doble Automobile, severally called a "Doble" because of their founding by Abner Doble. History There were four Doble brothers: Abner, William, John, and Warren. Their father became wealthy, patenting the Doble Pelton wheel. All were at one time associated with the automobile company, with Abner, John, and Warren as the leading lights. Abner Doble built his first steam car between 1906 and 1909 while still in high school, with the assistance of his brothers. It was based on components salvaged from a wrecked White Motor Company steamer, driving a new engine of the Doble brothers' own design. It did not run particularly wel ...

Guggenheim Safe Aircraft Competition
Daniel Guggenheim (July 9, 1856 – September 28, 1930) was an American mining magnate and philanthropist, and a son of Meyer and Barbara Guggenheim. By 1910 he directed the world's most important group of mining interests. He was forced out in 1922 and retired to philanthropy to promote aviation. His achievements include a system for innovation, as well as leadership in amicable labor relations, and major roles in aviation and rocketry. Biography Guggenheim was born and raised in Philadelphia, the son of Meyer Guggenheim and his wife Barbara. Meyer Guggenheim was of Jewish descent. Daniel Guggenheim was sent to Switzerland as a young man to study the Swiss lace and embroidery business, and to serve as a buyer for his father's import firm. The discovery of high-grade silver-lead ore in the Guggenheim mines in Leadville, Colorado, in 1881 became the foundation for the Guggenheim fortune in mining. In 1884, Daniel returned to the US to help manage the family's booming mining ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
