Van's RV-9
The Van's RV-9 and RV-9A are American two-seat, single-engine, low-wing homebuilt airplanes sold in kit form by Van's Aircraft of Aurora, Oregon. The RV-9 is the tail-wheel equipped version while the RV-9A features a nose-wheel.Downey, Julia: ''2008 Kit Aircraft Directory'', Kitplanes, Volume 24, Number 12, December 2007, page 78. Primedia Publications. Vandermeullen, Richard: ''2011 Kit Aircraft Buyer's Guide'', Kitplanes, Volume 28, Number 12, December 2011, page 74. Belvoir Publications. Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011–12'', page 125. WDLA UK, Lancaster UK, 2011. The RV-9 was built around a newly designed high aspect ratio wing, featuring a Roncz airfoil. It is similar in size and weight to the RV-6 and is externally similar to the RV-6 and the RV-7. Development The architect of the line of Van's aircraft, Richard VanGrunsven, designed the RV-9 as a departure from the concepts of the earlier RV series. The earlier ...

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 ...

Aircraft First Flown In 1997
An aircraft ( aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...

The Van's RV series aircraft are all-aluminum, low-wing monoplanes of monocoque construction. In 2023, over 11,000 Van's aircraft were flying worldwide, making up one third of the USA's experimental aircraft fleet. The Van's Aircraft factory is located at Aurora State Airport, Oregon. The company filed for Chapter 11, Title 11, United States Code, Chapter 11 bankruptcy protection in December 2023. History The company was founded by Richard VanGrunsven, Richard "Dick" VanGrunsven in 1973. In 2013, the company announced it would begin selling assembled RV-12 model aircraft as well on a limited basis. In December 2017, the company reported that its 10,000th aircraft had flown, an Van's Aircraft RV-7, RV-7 built in Martinsburg, West Virginia. As of November 2019, about 10,600 RV kits had been completed and flown, and thousands more are under construction. Com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2000s United States Civil Utility Aircraft
S, or s, is the nineteenth letter of the Latin alphabet, used in the English alphabet, the alphabets of other western European languages and other latin alphabets worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a "sh" phoneme, so the derived Greek letter Sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''Samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ), "to hiss". The original name of the letter "Sigma" may have been ''san'', but due to the ear ...

Thorp T-18
The Thorp T-18 is an American, two-place, all-metal, plans-built, homebuilt aircraft designed in 1963 by John Thorp.Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011–12'', page 98. WDLA UK, Lancaster UK, 2011. Tacke, Willi; Marino Boric; et al: ''World Directory of Light Aviation 2015–16'', page 105. Flying Pages Europe SARL, 2015. The aircraft was originally designed as an open cockpit aircraft, powered by a military surplus Lycoming O-290G ground power unit engine, but evolved into a fully bubble canopied aircraft powered by engines of up to . Design and development The T-18 was designed to be easily constructed from sheets of aluminum, and use a modified Lycoming O-290G. It was originally designed with an open cockpit and with the cylinder heads protruding through the engine cowling in the interest of simplicity. Even as originally designed, the cruising speed was quite high. The design showed great potential for higher performa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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, ...
