Leeon D. Davis
Leeon D. Davis (March 9, 1930 – April 7, 2007) was an American aircraft designer, noted for his homebuilt aircraft. Davis started building aircraft models at the age of six. Davis graduated with a high school education and a correspondence course in drafting and engineering from the Ryan Aeronautical Institute. Davis specialized as an aircraft mechanic while in the Air Force. Davis worked as a sheet-metal worker at Aero Commander before undertaking his own designs. On 6 March 1957, Davis formed Davis Aircraft Corporation to build aircraft of his own design. All of Davis' aircraft featured a characteristic V-tail, and the most successful of these was the DA-2. Plans to develop this basic design into an aircraft capable of certification Certification is the provision by an independent body of written assurance (a certificate) that the product, service or system in question meets specific requirements. It is the formal attestation or confirmation of certain characteristics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Aero Commander
Aero Commander was an aircraft manufacturer formed in 1944. In subsequent years, it became a subsidiary of Rockwell International and Gulfstream Aerospace. The company ceased aircraft production in 1986. History Aero was formed in Culver City, California, in 1944 to design and manufacture a light twin-engined transport aircraft. Ted Smith, a former project engineer at Douglas Aircraft Company, assembled a team of 14 engineers to design what would be the Aero Commander. Preliminary design was completed in 1946. The first prototype took flight on April 23, 1948, and was certified by the Civil Aeronautics Administration (CAA) in June, 1950. Three men funded the company's early efforts: Philadelphia attorney George Pew and Oklahoma City brothers William and Rufus Travis Amis. In September 1950, it became the Aero Design and Engineering Company of Oklahoma. Its facilities consisted of an aircraft hangar and manufacturing facility located at what is now Wiley Post Airport near Oklah ...

V-tail
The V-tail or ''Vee-tail'' (sometimes called a butterfly tail or Rudlicki's V-tailGudmundsson S. (2013). "General Aviation Aircraft Design: Applied Methods and Procedures" (Reprint). Butterworth-Heinemann. p. 489. , 9780123973290) of an aircraft is an unconventional arrangement of the tail control surfaces that replaces the traditional fin and horizontal surfaces with two surfaces set in a V-shaped configuration. It is not widely used in aircraft design. The aft edge of each twin surface is a hinged control surface called a ruddervator, which combines the functions of both a rudder and elevator. The V-tail was invented in 1930 by Polish engineer Jerzy Rudlicki and was tested for the first time on the Hanriot H-28 trainer aircraft, modified by a Polish aerospace manufacturer Plage and Laśkiewicz in the summer of 1931. Variants The X-shaped tail surfaces of the experimental Lockheed XFV were essentially a V tail that extended both above and below the fuselage. Conventional ...

Davis DA-2
__NOTOC__ The Davis DA-2 is a light aircraft designed in the United States in the 1960s and was marketed for Homebuilt aircraft, homebuilding. While it is a low-wing monoplane of largely conventional design with fixed tricycle undercarriage, the DA-2 is given a distinctive appearance by its slab-like fuselage construction and its V-tail. The pilot and a single passenger sit side-by-side. Construction of the aircraft is sheet aluminum throughout, with the sole compound curves formed a fiberglass cowling and fairings. The prototype made its first flight on May 21, 1966, and was exhibited at that year's Experimental Aircraft Association annual EAA AirVenture Oshkosh, fly-in, where it won awards for "most outstanding design" and "most popular aircraft". A major design consideration was ease of assembly for a first time home aircraft builder. Examples of this include: few curved components, a V-tail is one less control surface to build, and each wing is made from two sheets of alumi ...

Standard Airworthiness Certificate
A standard certificate of airworthiness is a permit for commercial passenger or cargo operation, issued for an aircraft by the civil aviation authority in the state/nation in which the aircraft is registered. For other aircraft such as crop-sprayers, a Special Airworthiness Certificate (not for commercial passenger or cargo operations) must be issued. Legal authority A certificate of airworthiness (CoA), or an airworthiness certificate, is issued for an aircraft by the civil aviation authority A civil aviation authority (CAA) is a national or supranational statutory authority that oversees the regulation of civil aviation, including the maintenance of an aircraft register. Role Due to the inherent dangers in the use of flight vehicles, ... in the state in which the aircraft is registered. The CoA attests that the aircraft is airworthy insofar as the aircraft conforms to its type design. Each certificate is issued in one of a number of different categories when the aircraft ...

Aircraft Designers
An 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 by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. 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, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...
