Design and development The Ranger was a development of the Aermacchi AL-60, which itself was based upon the Lockheed Model 60. NWI established its reputation as an aircraft overhauler and maintenance facility, but decided to enter the aircraft manufacturing business by buying the rights to the AL-60 in 1968. The aircraft featured a strut-braced high-wing, a six to eight seat enclosed cabin and optional fixed tricycle landing gear, convent ...

Floatplane
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call "floatplanes" "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, have greatly reduced the number of flying boats being built. However, numerous modern civilian aircraft have floatplane variants, most of these are offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four Stroke
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are clos ...

Lycoming Engines
Lycoming Engines is a major American manufacturer of aircraft engines. With a factory in Williamsport, Pennsylvania, Lycoming produces a line of horizontally opposed, air-cooled, four, six and eight-cylinder engines including the only FAA-certified aerobatic and helicopter piston engines on the market. The company has built more than 325,000 piston aircraft engines and powers more than half the world's general aviation fleet, both rotary and fixed wing. Lycoming is an operating division of Avco Corporation, itself a subsidiary of Textron. History Sewing machines, bicycles and fashion Lycoming dates its founding to 1845 by " Madame Ellen Curtis Demorest". However, the early history of the company (especially prior to 1860) is unclear; biographer Ishbel Ross notes that the marriage of Ellen Louise Curtis to William Jennings Demorest took place in 1858, somewhat later than the purported date of establishment of the company. A few years later in New York, between c. 1860 and 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Aviation Administration
The Federal Aviation Administration (FAA) is the largest transportation agency of the U.S. government and regulates all aspects of civil aviation in the country as well as over surrounding international waters. Its powers include air traffic management, certification of personnel and aircraft, setting standards for airports, and protection of U.S. assets during the launch or re-entry of commercial space vehicles. Powers over neighboring international waters were delegated to the FAA by authority of the International Civil Aviation Organization. Created in , the FAA replaced the former Civil Aeronautics Administration (CAA) and later became an agency within the U.S. Department of Transportation. Major functions The FAA's roles include: *Regulating U.S. commercial space transportation *Regulating air navigation facilities' geometric and flight inspection standards *Encouraging and developing civil aeronautics, including new aviation technology *Issuing, suspending, or revoking ...

Transport Canada
Transport Canada (french: Transports Canada) is the department within the Government of Canada responsible for developing regulations, policies and services of road, rail, marine and air transportation in Canada. It is part of the Transportation, Infrastructure and Communities (TIC) portfolio. The current Minister of Transport is Omar Alghabra. Transport Canada is headquartered in Ottawa, Ontario. History The Department of Transport was created in 1935 by the government of William Lyon Mackenzie King in recognition of the changing transportation environment in Canada at the time. It merged three departments: the former Department of Railways and Canals, the Department of Marine, and the Civil Aviation Branch of the Department of National Defence (c. 1927 when it replaced the Air Board) under C. D. Howe, who would use the portfolio to rationalize the governance and provision of all forms of transportation (air, water and land). He created a National Harbours Board and Trans-C ...

Aircraft Registration
An aircraft registration is a code unique to a single aircraft, required by Chicago Convention, international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft. Legal provisions In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft. An aircraft can only be registered once, in one jurisdiction, at a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycoming IO-720
The Lycoming IO-720 engine is a large displacement, horizontally opposed, eight-cylinder aircraft engine featuring four cylinders per side, manufactured by Lycoming Engines. There is no carburated version of the engine, which would have been designated O-720 and therefore the base model is the IO-720. The IO-720 and the Jabiru 5100 are the only flat-eight configuration aircraft engines currently in production. Design and development The engine has a fuel injection system which schedules fuel flow proportionally to the airflow, with fuel vaporization occurring at the intake ports. The engine has a displacement of 722 cubic inches (11.8 litres) and produces . The cylinders have air-cooled heads cast from aluminum alloy with a fully machined combustion chamber. The first IO-720 was type certified on 25 October 1961 to the CAR 13 standard as amended to 15 June 1956 including 13-1, 13-2, 13-3, 13-4. In 2009 a new IO-720-A1B cost US$113,621, with a rebuilt engine retailing for US$7 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluidyne Engineering
A Fluidyne engine is an alpha or gamma type Stirling engine with one or more liquid pistons. It contains a working gas (often air), and either two liquid pistons or one liquid piston and a displacer. The engine was invented in 1969. The engine was patented in 1973 by the Atomic Energy Authority UK. Engine operation Working gas in the engine is heated, and this causes it to expand and push on the water column. This expansion cools the air which contracts, at the same time being pushed back by the weight of the displaced water column. The cycle then repeats. The U-tube version has no moving parts in the engine other than the water and air, although there are two check valves in the pump. This engine operates at a natural resonance cycle that is "tuned" by adjusting the geometry, generally with a "tuning tube" of water. Engine as a pump In the classic configuration, the work produced via the water pistons is integrated with a water pump. The simple pump is external to the eng ...

Edo Aircraft Corporation
EDO Aircraft Corporation was an American aircraft manufacturing company known primarily for manufacturing pontoons for floatplanes. History The EDO Aircraft Corporation began operations on October 16, 1925 in College Point, New York. Although its founder, Earl Dodge Osborne, had dreamed of building airplanes, his first successful product line was EDO floats. Because of a new innovative design, the use of aluminum rather than wood, and the scarcity of hard-surfaced runways in the 1920s, demand built quickly for the floats. With the outbreak of World War II, the company's focus shifted, and EDO began to provide subassemblies for military aircraft of the U.S. Naval Air Corps, U.S. Army Air Forces, and foreign air forces. This shift in emphasis led to the company's being renamed the EDO Corporation in November 1947. EDO built a factory in 1940 on Long Island, designed by the NYC firm of Malmfeldt, Adams & Prentice. Construction cost was $305,000. EDO-Aire In June 1950, Ray Erw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flap (aircraft)
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and reduci ...
