Apex Alpha 2000
The Alpha Aviation Alpha 2000 is a two-seat, all-metal training and general aviation aircraft, designed by Chris Heintz and built in Hamilton, New Zealand. It continues the successful French Apex Aircraft's Robin R2000 series acquired upon Apex's purchase of the Avions Robin company. History 1971–1994 The original Avions Robin HR200 was designed by Christophe Heintz, to supplement the earlier Avions Robin designs of Jean Délémontez who also designed the popular post war wooden Jodel. The HR 200 prototype first flew on 19 July 1971, and entered production in 1973. The R2000 Alpha name was applied to a new aircraft which shared the fuselage of the HR 200, but had all new wing and tail surfaces, to allow aerobatics. The prototype R2000 Alpha flew on 15 January 1976 and production followed in 1977 to 1983. The aircraft features side-by-side seating, an innovative control stick mechanism which reduces the risk of blockage and an unusually large payload for an aerobatic aircraft ...

Flat-four
A flat-four engine, also known as a horizontally opposed-four engine or boxer engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than a straight-four engine. There is a minor, secondary unbalanced rotational torque pulse in the plane of the pistons, when a piston pair at one end of the engine is at TDC and the other pair at BDC. The TDC pair creates a torque greater than the BDC pair, so the net unbalanced torque pulse is the difference. The difference in TDC vs BDC inertial forces is explained in the Engine balance section. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robin Aircraft
Robin Aircraft is a French manufacturer of light aircraft. It succeeds to ''Centre-Est Aéronautique'', ''Avions Pierre Robin'' and Apex Aircraft (''Avions Robin'' and ''Robin Aviation''). History Centre-Est Aéronautique was formed by Pierre Robin (designer), Pierre Robin and Jean Délémontez, the principal designer of Jodel aircraft, in October 1957. It began manufacturing aircraft at Darois, near Dijon, France. The first aircraft was designed by Robin and Délémontez. It was based on the D10, a four-seater designed by Édouard Joly and Délémontez at Jodel, that was shelved when work on the Jodel D11 became more urgent. In collaboration with Robin it became the 'Jodel Robin'. It later became the DR100 model (Jodel's models all had D followed by a number). Robin and Délémontez continued to upgrade the design between 1957 and 1972. The DR100 range was succeeded by the DR200 range. Production continued in November 1970 under the name Avions Pierre Robin. The Robin DR400 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1970s New Zealand 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.

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple wings. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

Alpha Aviation Aircraft
Alpha (uppercase , lowercase ) is the first letter of the Greek alphabet. In the system of Greek numerals, it has a value of one. Alpha is derived from the Phoenician letter ''aleph'' , whose name comes from the West Semitic word for ' ox'. Letters that arose from alpha include the Latin letter and the Cyrillic letter . Uses Greek In Ancient Greek, alpha was pronounced and could be either phonemically long ( ː or short ( . Where there is ambiguity, long and short alpha are sometimes written with a macron and breve today: . * = ' "a time" * = ' "tongue" In Modern Greek, vowel length has been lost, and all instances of alpha simply represent the open front unrounded vowel . In the polytonic orthography of Greek, alpha, like other vowel letters, can occur with several diacritic marks: any of three accent symbols (), and either of two breathing marks (), as well as combinations of these. It can also combine with the iota subscript (). Greek grammar In the Attic– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cessna 152
The Cessna 152 is an American two-seat, fixed- tricycle-gear, general aviation airplane, used primarily for flight training and personal use. It was based on the earlier Cessna 150 incorporating a number of minor design changes and a slightly more powerful engine with a longer time between overhaul. The Cessna 152 has been out of production for forty years, but many are still airworthy and are in regular use for flight training. Development First delivered in 1977 as the 1978 model year, the 152 was a modernization of the proven Cessna 150 design. The 152 was intended to compete with the new Beechcraft Skipper and Piper Tomahawk, both of which were introduced the same year. Additional design goals were to improve useful load through a gross weight increase to , decrease internal and external noise levels and run better on the then newly introduced Avgas fuel.. As with the 150, the great majority of 152s were built at the Cessna factory in Wichita, Kansas. A number o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piper Tomahawk
The Piper PA-38-112 Tomahawk is a two-seat, fixed tricycle gear general aviation airplane, originally designed for flight training, touring and personal use. Design and development The Tomahawk is a single-engined low-wing cantilever monoplane with a T-tail and an enclosed cabin for two. It has a fixed tricycle landing gear and is powered by a Lycoming O-235 four-cylinder piston engine with a twin-bladed tractor propeller. The Tomahawk has two front-hinged doors for access to the cabin. The Tomahawk was Piper's attempt at creating an affordable two-place trainer. Before designing the aircraft, Piper widely surveyed flight instructors for their input into the design. Instructors requested a more spinnable aircraft for training purposes, since other two-place trainers such as the Cessna 150 and 152 were designed to spontaneously fly out of a spin. The Tomahawk's NASA GA(W)-1 Whitcomb airfoil addresses this requirement by making specific pilot input necessary in recovering from ...

Grumman American AA-1
The Grumman American AA-1 series is a family of light, two-seat aircraft. The family includes the original American Aviation AA-1 Yankee and AA-1A Trainer along with the TR-2. The TR-2 has a cruise propeller and the trainer has a climb prop. Typically the TR-2 came with more navigation instruments and was better for cross country flying because of its speed and lower fuel consumption. The family also includes the Grumman American AA-1B Trainer and TR-2, plus the Gulfstream American AA-1C Lynx and T-Cat. Development history The Yankee was originally designed in 1962 by Jim Bede as the Bede BD-1, BD-1 and was intended to be sold as a kit-built aircraft. Bede decided to certify the design under the then-new Federal Aviation Regulations, FAR Part 23 rules and offer it as a completed aircraft. No BD-1 kits were ever sold. The prototype first flew on July 11, 1963, and featured folding wings for trailering and ease of storage. Bede formed a company, Bede Aviation Corporation, ...
