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).

1930s Aircraft Piston Engines
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Pratt & Whitney R-1340 Wasp
The Pratt & Whitney R-1340 Wasp is an aircraft engine of the reciprocating type that was widely used in American aircraft from the 1920s onward. It was the Pratt & Whitney aircraft company's first engine, and the first of the famed Wasp series. It was a single-row, nine-cylinder, air-cooled, radial design, and displaced 1,344 cubic inches (22 L); bore and stroke were both 5.75 in (146 mm). A total of 34,966 engines were produced. As well as numerous types of fixed-wing aircraft, it was used to power helicopters, the Agusta-Bell AB.102 and the Sikorsky H-19, and a class of airship, the K-class blimp. In 2016, it received designation as a Historic Engineering Landmark from the American Society of Mechanical Engineers.

Alvis Leonides
The Alvis Leonides was a British air-cooled nine-cylinder radial aero engine first developed by Alvis Car and Engineering Company in 1936. Design and development Development of the nine-cylinder engine was led by Capt. George Thomas Smith-Clarke. The prototype engine, called 9ARS and which weighed 693 lb and developed 450 hp, was run in December 1936. In 1938 Airspeed (1934) Ltd lent their test pilot, George Errington, and their much rebuilt Bristol Bulldog (''K3183''), to carry out test flights. Development was continued at a reduced pace during the Second World War and following testing in an Airspeed Oxford and an Airspeed Consul (''VX587''). Alvis was ready to market the engine in 1947 as the Series 500 (502, 503 and sub-types) for aeroplanes and Series 520 for helicopters. (Most helicopter engines were direct drive — no reduction gearbox — with a centrifugal clutch and fan cooling). The first production use was the Percival Prince, which flew in Ju ...

Benzole
In the United Kingdom, benzole or benzol is a coal-tar product consisting mainly of benzene and toluene. It was originally used as a 'motor spirit', as was petroleum spirits. Benzole was also blended with petrol and sold as a motor fuel under trade names including "National Benzole Mixture" and "Regent Benzole Mixture". Confusingly, in certain languages, such as German, Hungarian, Ukrainian and Russian the word "benzol" (or benzole) means benzene, and in some of these languages, words pronounced like benzene (e.g. the German word "Benzin") can mean petrol, or gasoline.Collins German Concise Dictionary, 1991, See also * Antiknock agent An antiknock agent is a gasoline additive used to reduce engine knocking and increase the fuel's octane rating by raising the temperature and pressure at which auto-ignition occurs. The mixture known as gasoline or petrol, when used in high compr ... References External links The National Benzole CompanyInsolvent since 8 April 2013 Coal ...

Benzine
Petroleum benzine is a hydrocarbon-based solvent mixture that is classified by its physical properties (e.g. boiling point, vapor pressure) rather than a specific chemical composition. This complicates distinction within the long list of petroleum distillate solvent mixtures: mineral spirits, naphtha, petroleum naptha, white gas, white spirits, turps substitute, mineral turpentine, petroleum ether, ligroin, and Stoddard solvent. The chemical composition of a petroleum distillate can also be modified to afford a solvent with reduced concentration of unsaturated hydrocarbons, ''i.e.'' alkene In organic chemistry, an alkene is a hydrocarbon containing a carbon–carbon double bond. Alkene is often used as synonym of olefin, that is, any hydrocarbon containing one or more double bonds.H.

Prague Aviation Museum, Kbely
Kbely Aviation Museum (''Letecké Muzeum Kbely'') is the largest aviation museum in the Czech Republic and one of the largest of its kind in Europe. It is located to the north-east of Prague, at the military airport Kbely. Creation of the museum During the mid-1960s, the Prague Military Museum commenced a programme to recover, restore and preserve historic aircraft from around the country for eventual display at Kbely. Initially, one hangar was used, and about fifty aircraft were placed on public display. The aircraft collection continued to grow, and one of the original Wagner-type hangars on the airfield was brought into use, and now contains the earliest aircraft types on display. Another Picha-type hangar has also been added to bring the number of hangars housing the large and varied collection to four. The aircraft collection The collection at Kbely now includes 275 aircraft, of which approximately 110 are on public display at any given time. The museum contains many Czech d ...

Praga BH-41
The Praga BH-41, later redesignated E-41, was a military advanced trainer aircraft produced in Czechoslovakia during the 1930s.Taylor 1989, p.751''The Illustrated Encyclopedia of Aircraft'' p.2777 Design and development Designed in response to a Defence Ministry competition and based on the BH-39, it was a conventional biplane design with unstaggered two-bay wings of equal span. The pilot and instructor sat in open cockpits in tandem, and the fixed tailskid undercarriage featured divided main units. The powerplant had been specified by the government to be the Hispano-Suiza 8Fb which were then being manufactured under licence by Škoda. The E-41 was selected as the winner of the competition, and a contract for 43 aircraft was signed. Praga also produced a version powered by a ZOD 260 radial diesel engine, designated the E-141. This was not a success and only a single prototype was built. In 1936, a BH-41 was fitted with a Walter Pollux II engine, and designated the E-241. Fo ...
