MC15E Cri-Cri
The Colomban Cri-Cri, also spelled Cricri, is the smallest twin-engined crewed aircraft in the world, designed in the early 1970s by French aeronautical engineer Michel Colomban. The name ''Cri-Cri'' comes from the nickname of Christine, one of Colomban's daughters. 'Cri-cri' 'or 'cricri' is also the French term for the sound of a cricket or a cicada, or an informal name for the insects themselves, but it is unclear if this double meaning was intended by Colomban himself. Design and development Colomban designed the aircraft to be easy to build and fly, and the closeness of the two engines to each other, around the centreline, meant that it could be flown by pilots only qualified to fly single-engined aircraft because even with the complete failure of one engine, with hands and feet off the controls, the only effect would be a gentle turn. The cockpit canopy was carefully designed to direct effective airflow over the tail surfaces in this situation. The plans-built aircraft ...

Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental aircraft, Experimental under Federal Aviation Administration, FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on m ...

1970s French Sport Aircraft
Year 197 ( CXCVII) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 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.

Beaujon Enduro
The Beaujon Enduro is a single-seat, American high-wing, pusher configuration ultralight aircraft. The Enduro was introduced in 1978 and remains available as plans from Beaujon Aircraft of Ardmore, Oklahoma.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page B-8. Cybair Limited Publishing, 2001. Development The Enduro is an early ultralight design that was first developed before the United States ultralight category and its FAR 103 ''Ultralight Vehicles'' rules were finalized, but it fits into the requirements including the category's maximum empty weight. With the originally specified Briggs & Stratton 401417, four-stroke, 656 cc, lawn mower powerplant the aircraft has an empty weight of . The engine burns only per hour giving an endurance of 5 hours on the specified of fuel, hence the aircraft's name. Reviewer Andre Cliche says of Beaujon's designs that they are "beautifully simple".

Aerosport Rail
The Aerosport Rail is an American minimalist ultralight aircraft, designed by Harris Woods and built by Aerosport Inc. The aircraft was first flown on 14 November 1970. Design and development The Rail is little more than a 2 by 5 inch squared aluminium tube (rail) with all-metal wings and a T-tail. The pilot sits on the tube, just ahead of and above the wings. Two small two-cycle engines derated to are mounted on struts behind the seat on either side of centerline, driving pusher propellers. Individual fiberglass fuel tanks are mounted in front of each engine. About 175 sets of plans were sold between 1970 and 1977. The follow-on design, the Aerosport Quail uses the Rail's wing design for an enclosed tractor configuration homebuilt aircraft.

Piston Engine
A reciprocating engine, more often known as a piston engine, is a heat engine that uses one or more Reciprocating motion, reciprocating pistons to convert high temperature and high pressure into a Circular motion, rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition engine, spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition engine, compression-ignition (CI) engine, where the air within the cylinder is compressed, Adiabatic process, thus heating it, so that the heated air ignites fuel that is injected diesel engine, then or hot-bulb engine, earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-cylinder
A single-cylinder engine, sometimes called a thumper, is a piston engine with one cylinder. This engine is often used for motorcycles, motor scooters, motorized bicycles, go-karts, all-terrain vehicles, radio-controlled vehicles, power tools and garden machinery (such as chainsaws, lawn mowers, cultivators, and string trimmers). Single-cylinder engines are made both as 4-strokes and 2-strokes. Characteristics Compared with multi-cylinder engines, single-cylinder engines are usually simpler and compact. Due to the greater potential for airflow around all sides of the cylinder, air cooling is often more effective for single cylinder engines than multi-cylinder engines. This reduces the weight and complexity of air-cooled single-cylinder engines, compared with liquid-cooled engines. Drawbacks of single-cylinder engines include a more pulsating power delivery through each cycle and higher levels of vibration. The uneven power delivery means that often a single-cylinder engine ...

MacCready Solar Challenger
The Solar Challenger was a solar-powered aircraft designed by Paul MacCready's AeroVironment. The aircraft was designed as an improvement on the Gossamer Penguin, which in turn was a solar-powered variant of the human-powered Gossamer Albatross. It was powered entirely by the photovoltaic cells on its wing and stabilizer, without even reserve batteries, and was the first such craft capable of long-distance flight. In 1981, it successfully completed a 163-mile (262 km) demonstration flight from France to England. History The Solar Challenger was designed by a team led by Paul MacCready as a more airworthy improvement on the Gossamer Penguin, directly incorporating lessons learned from flight testing the earlier aircraft.Solar Challenger - Exclusiv ...

Airbus E-Fan
The Airbus E-Fan is a prototype two-seater electric aircraft that was under development by Airbus. It was flown in front of the world press at the Farnborough Airshow in the United Kingdom in July 2014. The target market was intended to be pilot training, but production of the aircraft was cancelled in April 2017. Design and development Airbus Group developed this electric aircraft with Aero Composites Saintonge. The aircraft uses on-board lithium-ion batteries to power the two electric motors and can carry one pilot and one passenger. A test flight was conducted in April 2014 at Bordeaux–Mérignac Airport, France, landing in front of a large audience, the French Minister of Industry Arnaud Montebourg being one of them. At the 2014 Farnborough Airshow, Airbus announced that the E-Fan 2.0 would go into production by 2017 with a side-by-side seating layout. Airbus stated at that time that there are plans for development of a commercial regional aircraft in the near future. The E ...
