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, ...

Servo Tab
A servo tab is a small hinged device installed on an aircraft control surface to assist the movement of the Flight control surfaces, control surfaces. Introduced by the German firm Flettner, servo tabs were formerly known as Flettner tabs. Servo tabs are not true servomechanisms, as they do not employ negative feedback to keep the control surfaces in a desired position; they only provide a mechanical advantage to the pilot. Servo tabs A servo tab, or balance tab, moves in the direction opposite to the desired movement of the control surface. It deflects airflow, generating force on the whole control surface in the desired direction. The tab has a leverage advantage, being located well aft of the control surface hinge line, and thus its airflow deflection moves the control surface in the opposite direction, overcoming the resistance generated by the airflow deflection of the control surface. This has the effect of reducing the control force required from the pilot to move the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminum
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Adhesive
Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation. The use of adhesives offers certain advantages over other binding techniques such as sewing, mechanical fastenings, and welding. These include the ability to bind different materials together, the more efficient distribution of stress across a joint, the cost-effectiveness of an easily mechanized process, and greater flexibility in design. Disadvantages of adhesive use include decreased stability at high temperatures, relative weakness in bonding large objects with a small bonding surface area, and greater difficulty in separating objects during testing. Adhesives are typically organized by the method of adhesion followed by ''reactive'' or ''non-reactive'', a term which refers to whether the adhesive chemically reacts in order to harden. Alternatively, they can be organized either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canopy (aircraft)
An aircraft canopy is the transparent enclosure over the cockpit of some types of aircraft. An aircraft canopy provides a controlled and sometimes Cabin pressurization, pressurized environment for the aircraft's occupants, and allows for a greater field of view over a traditional flight deck. A canopy's shape is a compromise designed to minimize aerodynamic drag, while maximizing visibility for Aircraft pilot, pilots and other crewmembers. History Very early aircraft had no canopies. The pilots were exposed to the wind and weather, although most flying was done in good weather. Through World War I most aircraft had no canopy, although they often had a small windshield to deflect the prop wash and wind from hitting the pilot in the face. In the 1920s and 1930s, the increasing speed and altitude of airplanes necessitated a fully enclosed cockpit and canopies became more common. Early canopies were made of numerous pieces of flat glass held in position by a frame and muntins. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiger Aircraft
Tiger Aircraft LLC was an American aircraft manufacturer from 1999 to 2006 based in Martinsburg, West Virginia, United States. History The company was established in 1999 with the aim of returning the AG-5B Tiger to production. Tiger Aircraft followed in the footsteps of Grumman American, Gulfstream American and American General Aviation Corporation in manufacturing the Tiger. Tiger Aircraft had ceased operations by November 2006 and filed for bankruptcy in January 2007. Financial difficulties Tiger Aircraft was headed by President and Chief Operating Officer N. Gene Criss between August 25, 2003, and early August 2006. Criss was fired by the board for allegedly selling the assets of the company to Network Hosts without authority. The four companies that owned Tiger Aircraft applied to a West Virginia Circuit Court at that time for a restraining order to prevent further sales and also to declare the previous deals invalid. By the middle of 2006, Tiger Aircraft was experienci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulfstream American GA-7 Cougar
The Gulfstream American GA-7 Cougar is an American all-metal, 4-seat, twin-engined light aircraft. The Cougar was a twin-engine development of the Gulfstream American AA-5B Tiger and traces its lineage to the AA-1 Yankee Clipper and the Bede BD-1. Development As a development of the company's single-engined designs, Grumman American developed a twin-engined version, designated the GA-7 which it named the Cougar, in keeping with the existing Lynx, Cheetah and Tiger names for aircraft in the company's line. The prototype Cougar with two Lycoming O-320 engines first flew on the 29 December 1974. The prototype had a sliding canopy but this was soon changed to a starboard side door on the production aircraft. With other rework required the production prototype did not fly until 14 January 1977.Wood, Derek: ''Jane's World Aircraft Recognition Handbook'', page 233. Jane's Publishing Company, 1982.

NACA
The National Advisory Committee for Aeronautics (NACA) was a United States federal agency that was founded on March 3, 1915, to undertake, promote, and institutionalize aeronautical research. On October 1, 1958, the agency was dissolved and its assets and personnel were transferred to the newly created National Aeronautics and Space Administration (NASA). NACA is an initialism, pronounced as individual letters rather than as a whole word, as was NASA during the early years after being established. Among other advancements, NACA research and development produced the NACA duct, a type of air intake used in modern automotive applications, the NACA cowling, and several series of NACA airfoils, which are still used in aircraft manufacturing. During World War II, NACA was described as "The Force Behind Our Air Supremacy" due to its key role in producing working superchargers for high altitude bombers, and for producing the laminar wing profiles for the North American P-51 Mustan ...
