Van's Aircraft RV-7
The Van's RV-7 and RV-7A are two-seat, single-engine, low-wing homebuilt airplanes sold in kit form by Van's Aircraft. The RV-7 is the tail-wheel equipped version, while the RV-7A features a nose-wheel.Vandermeullen, Richard: ''2011 Kit Aircraft Buyer's Guide'', Kitplanes, Volume 28, Number 12, December 2011, page 74. Belvoir Publications. The RV-7 was the replacement of the RV-6, replacing the RV-6 in 2001. It is externally similar to the earlier model, with longer wings, larger fuel tanks and a larger rudder to improve spin recovery characteristics. Development Van's aircraft designer Richard VanGrunsven Richard E. "Dick" VanGrunsven (born 1939) is an American aircraft designer and kit plane manufacturer. The number of VanGrunsven-designed homebuilt aircraft produced each year in North America exceeds the combined production of all commercial ge ... designed the RV-7 to replace the RV-6, which was a two-seat side-by-side development of the RV-4.

Hartzell Propeller
Hartzell Propeller is an American manufacturer that was founded in 1917 by Robert N. Hartzell as the Hartzell Walnut Propeller Company. It produces composite and aluminum propellers for certified, homebuilt, and ultralight aircraft. The company is headquartered in Piqua, Ohio.Purdy, Don: ''AeroCrafter - Homebuilt Aircraft Sourcebook'', page 84. BAI Communications. Hartzell also produces spinners, governors, ice protection systems, and other propeller controls. History Robert Hartzell grew up in the village of Oakwood, Ohio, just a block from Hawthorn Hill, where Orville Wright lived. From the 1890s until the late 1910s, Hartzell's father and grandfather operated a sawmill and lumber supply company in Greenville, Ohio (later moved to Piqua, Ohio) that also manufactured items such as wagons and gun stocks for World War I. On the side, Robert owned a small airplane and did maintenance on it as a young man. In 1917, Orville Wright suggested that Hartzell use his walnut tr ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. 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 can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

1990s United States Civil Utility Aircraft
Year 199 ( CXCIX) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was sometimes known as year 952 ''Ab urbe condita''. The denomination 199 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.

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 under 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 most of the maintenance, repairs, and inspections themsel ...

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 the modified Lycoming O-290G powerplant. 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 high ... [...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, 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, based in Cleveland, Ohio, to produce the aircraft, but the BD-1 never entered production as a certified aircraft. At that time the FAA was hesitant to certify a light aircraft with folding wings. The certification process was complex and expensive and disa ...

Lycoming O-360
The Lycoming O-360 is a family of four-cylinder, direct-drive, horizontally opposed, air-cooled, piston aircraft engines. Engines in the O-360 series produce between 145 and 225 horsepower (109 to 168 kW), with the basic O-360 producing 180 horsepower. The engine family has been installed in thousands of aircraft, including the Cessna 172, Piper Cherokee/Archer, Grumman Tiger, and many home-built types. It has a factory rated time between overhaul (TBO) of 2000 hours or twelve years. O-360 family engines are also widely used in airboats, most notably in the Hurricane Aircats used by the US Army during the Vietnam War. The first O-360 certified was the A1A model, certified on 20 July 1955 to United States CAR 13 effective March 5, 1952 as amended by 13-1 and 13-2.
