Norton NR642
The Norton NR642 (Originally the Aerotor 90) is a British aircraft engine that was designed and produced by Norton Motorcycle Company in the 1990s for use in light aircraft (particularly by amateur constructors) and UAVs.Lambert 1991, p.709 Design and development The NR642 is a twin-rotor Wankel engine. It is a displacementMoll 1989, p.20 petrol engine design, with a heavy-duty 2.94:1 reduction gearbox. Cooling is provided by a fan for the rotors, plus liquid cooling for the housing. It was designed to meet JAR-E and FAR 23 regulatory requirements. Norton aimed for 1,500 hours running time between overhauls but was initially specifying 200-300 hours. The NR642 first flew in late 1989, with two units installed on a Rutan Long-EZ to create what its builder called a "Twin EZ"."Rotary Power by Norton Motors", p.20 Applications *Aircorp Bushmaster *Rutan Long-EZ The Rutan Model 61 Long-EZ is a tandem 2-seater homebuilt aircraft designed by Burt Rutan's Scaled Composites. ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market. Development history * 1903: Manly-Balzer engine sets standards for later radial engines. * 1910: Coandă-1910, an unsuccessful ducted fan aircraft exhibited at Paris Aero Salon, powered by a piston engine.

Norton Motorcycle Company
The Norton Motorcycle Company (formerly Norton Motorcycles.) is a brand of motorcycles headquartered in Solihull, West Midlands, (originally based in Birmingham), England. For some years around 1990, the rights to use the name on motorcycles were owned by North American financiers. Currently it is owned by Indian motorcycle giant TVS Motor Company. The business was founded in 1898 as a "fittings and parts for the two-wheel trade" manufacturer.Holliday, Bob, ''Norton Story'', Patrick Stephens, 1972, p.11. By 1902 the company had begun manufacturing motorcycles with bought-in engines. In 1908 a Norton-built engine was added to the range. This began a long series of production of single and eventually twin-cylinder motorcycles, and a long history of racing involvement. During the Second World War Norton produced almost 100,000 of the military Model 16 H and Big 4 sidevalve motorcycles. Associated Motor Cycles bought the company in 1953. It was reformed as Norton-Vil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wankel Engine
The Wankel engine (, ) is a type of internal combustion engine using an eccentric (mechanism), eccentric Pistonless rotary engine, rotary design to convert pressure into rotating motion. The concept was proven by German engineer Felix Wankel, followed by a commercially feasible engine designed by German engineer Hanns-Dieter Paschke. The Wankel engine's rotor is similar in shape to a Reuleaux triangle, with the sides having less curvature. The rotor spins inside a figure-eight-like epitrochoidal housing around a fixed gear. The midpoint of the rotor moves in a circle around the output shaft, rotating the shaft via a Cam (mechanism), cam. In its basic gasoline-fuelled form, the Wankel engine has lower thermal efficiency and higher exhaust emissions relative to the Four-stroke engine, four-stroke reciprocating engine. This thermal inefficiency has restricted the Wankel engine to limited use since its introduction in the 1960s. However, many disadvantages have mainly been overcome ...

JAR-E
The Joint Aviation Requirements (JAR) were a set of common comprehensive and detailed aviation requirement issued by the Joint Aviation Authorities, intended to minimise Type Certification problems on joint ventures, and also to facilitate the export and import of aviation products.https://www.faa.gov/regulations_policies/rulemaking/committees/documents/media/GACOj23T4-11301992.pdf They were recognised by the civil aviation authorities of participating countries as an acceptable basis for showing compliance with their national airworthiness codes. The European Aviation Safety Agency (EASA) was created in 2003 and reached full functionality in 2008, and has since taken over most of the JAA functions. JAA Certification Specifications, formerly known as JARs, are recognised by EASA as an acceptable basis for showing compliance with their national airworthiness codes.

FAR 23
The Federal Aviation Regulations (FARs) are rules prescribed by the Federal Aviation Administration (FAA) governing all aviation activities in the United States. The FARs comprise Title 14 of the Code of Federal Regulations (14 CFR). A wide variety of activities are regulated, such as aircraft design and maintenance, typical airline flights, pilot training activities, hot-air ballooning, lighter-than-air aircraft, human-made structure heights, obstruction lighting and marking, model rocket launches, commercial space operations, model aircraft operations, unmanned aircraft systems (UAS) and kite flying. The rules are designed to promote safe aviation, protecting pilots, flight attendants, passengers and the general public from unnecessary risk. FAR vs. 14 CFR Since 1958, these rules have typically been referred to as "FARs", short for Federal Aviation Regulations. However, another set of regulations (Title 48) is titled "Federal Acquisition Regulations", and this has led t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time Between Overhauls
Time between overhauls (abbreviated as TBO or TBOH) is the manufacturer's recommended number of running hours or calendar time before an aircraft engine or other component requires overhaul. On rotorcraft, many components have recommended or mandatory TBOs, including main rotor blades, tail rotor blades and gearboxes. For engines, the time between overhauls is generally a function of the complexity of the engine and how it is used. Piston-based engines are much more complex than turbine-powered engines, and generally have TBOs on the order of 1,200 to 2,000 hours of running time. They tend toward the lower number if they are new designs, or include boosting options such as a turbocharger. In comparison, jet engines and turboprop A turboprop is a Gas turbine, gas turbine engine that drives an aircraft Propeller (aeronautics), propeller. A turboprop consists of an intake, reduction drive, reduction gearbox, gas compressor, compressor, combustor, turbine, and a propellin .. ...

Rutan Long-EZ
The Rutan Model 61 Long-EZ is a tandem 2-seater homebuilt aircraft designed by Burt Rutan's Scaled Composites. The Long-EZ has a canard layout, a swept wing with wingtip rudders, and a pusher engine and propeller. The tricycle landing gear has fixed main wheels with streamlined spats and a retractable nosewheel. Its predecessor was the VariEze, plans for which were first available to homebuilders in 1976. The prototype Long-EZ, N79RA, first flew on June 12, 1979. Design The Long-EZ was a scaled-up redesign of the VariEze predecessor, allowing for the use of readily available Lycoming aircraft engines instead of the Volkswagen-derived engines or hard-to-find small Continentals for which the VariEze was designed. Changes from the VariEze included a larger main wing with modified Eppler 1230 airfoil and less sweep, larger strakes containing more fuel and baggage storage, and a slightly wider cabin. The canard uses the same GU25-5(11)8 airfoil as the VariEze. Plans were offer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircorp Bushmaster
The Aircorp B2-N Bushmaster is a prototype Australian light aircraft designed for aerobatic, touring, and utility use.Taylor 1993, p.914 It first flew in 1989 and did not enter production. Design and development The Bushmaster is a high-wing, strut-braced monoplane of conventional design with fixed, tailwheel undercarriage. It has two seats, side-by-side, in an enclosed cabin. Fuselage construction is of welded steel tube, covered in fabric, and the wing is all metal. It is powered by a nose-mounted engine driving a tractor propeller. This engine was originally a Norton Aerotor 90 wankel engine, also intended to power production examples. The prototype, ''VH-BOI'', first flew on 28 October 1989. Certification for the original Norton powerplant was delayed, so it was changed to a Lycoming O-235 after this first flight.Carman 1992, p.11 The engine change necessitated some other modifications to the aircraft, including changes to the engine cowling and the undercarriage.
