Fluorine
Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative reactive element, it is extremely reactive, as it reacts with all other elements except for the light inert gases. Among the elements, fluorine ranks 24th in universal abundance and 13th in terrestrial abundance. Fluorite, the primary mineral source of fluorine which gave the element its name, was first described in 1529; as it was added to metal ores to lower their melting points for smelting, the Latin verb meaning 'flow' gave the mineral its name. Proposed as an element in 1810, fluorine proved difficult and dangerous to separate from its compounds, and several early experimenters died or sustained injuries from their attempts. Only in 1886 did French chemist Henri Moissan isolate elemental fluorine using low-temperature electrolysis, a process still employed for modern pr ...

Fieseler F2 Tiger
The Fieseler F2 Tiger was a German single-seat aerobatic biplane which was flown to victory in the 1934 World Aerobatics Competition (WAC) by its designer/builder Gerhard Fieseler. Design and development Gerhard Fieseler started his own company in 1930 in the former Segelflugzeugbau company at Kassel, Germany. Fieseler was a World War I German fighter ace with almost 20 kills to his credit, and became a world class competition aerobatic pilot. To compete in International competitions Fieseler designed and built the Fieseler F2 Tiger single-seat biplane, powered by a Walter Pollux II air-cooled 9-cylinder radial. The 1934 World Aerobatics Competition, held in Paris, was the first of its kind, and, despite the deaths of two pilots and a few crashes, the competition continued and Fieseler won, although he went over the time limit due to a loose harness, beating his nearest competitor, Michel Detroyat of France (who flew an M.S.225), by 23 points (645.2 to 622.9). Fieseler r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dassault Mirage F2
The Dassault Mirage F2 was a French prototype two-seat ground attack/fighter aircraft, which was designed to serve as a test bed for the SNECMA TF306 turbofan engine. The F2 also influenced the subsequent Dassault Mirage G, a variable geometry design. Design and development Dassault were tasked in the early 1960s to design a low-altitude intruder that did not have the high approach speeds associated with the delta wing of the Mirage III. Unlike the Mirage III, the F2 had a high-mounted swept wing and horizontal tail surfaces. The prototype powered by a Pratt & Whitney TF30 turbofan first flew on 12 June 1966. It was re-engined with the SNECMA TF306 for the second flight on 29 December 1966. Two parallel developments were a single-seat Mirage F3 interceptor and a scaled-down and simpler Mirage F1. Eventually the French Air Force chose to develop the French-engined F1, and the F2 did not enter production. The fuselage and engine from the F2 formed the basis of a variable-geome ...

Beechcraft F-2 Expeditor
The Beechcraft Model 18 (or "Twin Beech", as it is also known) is a 6- to 11-seat, twin-engined, low-wing, tailwheel light aircraft manufactured by the Beech Aircraft Corporation of Wichita, Kansas. Continuously produced from 1937 to November 1969 (over 32 years, a world record at the time), over 9,000 were built, making it one of the world's most widely used light aircraft. Sold worldwide as a civilian executive, utility, cargo aircraft, and passenger airliner on tailwheels, nosewheels, skis, or floats, it was also used as a military aircraft."Beechcraft D18S Twin Beech."

Taronga Zoo Ferry Services
The Taronga Zoo ferry service is a ferry route in Sydney, New South Wales, Australia. It connects Taronga Zoo with the transport hub at Circular Quay. The route forms part of the Sydney Ferries network. In 2013, the Taronga Zoo ferry service was given the designation of F2 as part of a program to number all Sydney Ferries, Sydney Trains and light rail lines. Some F2 Taronga Zoo services are combined with F6 Mosman services, extending to Mosman Bay. History The first service to Taronga Zoo commenced on 24 September 1916 with a vehicular ferry taking the elephant 'Jessi' across the harbour to her new home from the old zoo at Moore Park.

DKW F2
DKW (''Dampf-Kraft-Wagen'', en, "steam-powered car", also ''Deutsche Kinder-Wagen'' en, "German children's car". ''Das-Kleine-Wunder'', en, "the little wonder" or ''Des-Knaben-Wunsch'', en, "the boy's wish"- from when the company built toy two-stroke engines) was a German car- and motorcycle- marque. DKW was one of the four companies that formed Auto Union in 1932 and thus became an ancestor of the modern-day Audi company.

Alta F2
The Alta Car and Engineering Company was a British sports and racing car manufacturer, commonly known simply as Alta. Their cars contested five FIA World Championship races between 1950 and 1952, as well as Grand Prix events prior to this. They also supplied engines to a small number of other constructors, most notably the Connaught and HWM teams. Early history The company was founded by engineer Geoffrey Taylor (1903–1966) in Surbiton, Surrey, and produced its first automobile in 1929. Alta's first vehicle was a sports car powered by a 1.1L engine, featuring an aluminium block, wet liners, and shaft-driven twin overhead camshafts, which Taylor designed himself. It was offered in naturally aspirated or supercharged form giving . A choice of four speed non- synchromesh or pre-selector gearboxes was available. These were mounted on a low-slung chassis frame with open two- or four-seat bodies. Thirteen were made, of which five are thought to survive. This design, and i ...

H&BR Class F2
The H&BR Class F2 (LNER Class N12) was a class of 0-6-2T steam locomotives of the Hull and Barnsley Railway. It was designed by Matthew Stirling and nine locomotives were built by Kitson & Co. in 1901. Equipment The locomotives had domeless boilers and rounded cabs and were fitted with vacuum brakes. After the Grouping in 1923, they were rebuilt with a variety of boilers, some domed and some domeless. Use They were used for goods trains, banking, assembling mineral trains in colliery sidings and occasionally for passenger work. Withdrawal All but one were withdrawn between 1936 and 1938. The survivor passed to British Railways British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most of the overground rail transport in Great Britain from 1948 to 1997.

EMD F2
The EMD F2 was a freight-hauling diesel locomotive built by General Motors Electro-Motive Division between July 1946 and November 1946. It succeeded the FT model in GM-EMD's F-unit sequence, and was replaced in turn by the F3. The F2 was in many respects a transitional type between those two; it kept the rated D8 generator from the FT due to late development of the new D12 generator intended for the F3, but in a revised carbody design and internal layout that would be continued through the rest of the F-unit series. 74 cab-equipped lead A units and 30 cabless booster B units were produced. There are no reliable recognition features for an F2. They were built with what has become known as 'Type 1' side panels, with three portholes and no filter grilles, but this was carried over into early F3 production and in any case, could be changed later by the customer. Like some early F3s, they were built with small side numberboards on the nose. They, and all subsequent F-units, are re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
