Bede BD-1
The Bede BD-1 was a two-seat, single-engine, low-wing monoplane, the first design of American aeronautical engineer Jim Bede. The BD-1 was designed in 1960 as a kit-built aircraft intended for home assembly by amateur builders. Design goals included a kit price of $US 2500, including a rebuilt 100 hp (75 kW) engine and a cruise speed of 130 knots (240 km/h). The prototype N624BD first flew in 1962. No kits were sold however, and it was not until Bede had been removed from the company and the design was reworked - including the removal of the folding wing feature - that it entered production as the American Aviation AA-1. Design The BD-1 was a low-wing monoplane of all-metal construction, utilizing aluminium honeycomb construction and a laminar flow wing. The aircraft was predominantly of bonded, rather than riveted, construction. It featured a sliding canopy and two seats. The aircraft was designed to be towed behind a car to allow it to be stored at home in a ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Aircraft
A light aircraft is an aircraft that has a maximum gross takeoff weight of or less.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 308. Aviation Supplies & Academics, 1997. Light aircraft are used as utility aircraft commercially for passenger and freight transport, sightseeing, photography, and other roles, as well as personal use. Examples of aircraft that are at the maximum gross takeoff weight for this category include the de Havilland Canada DHC-6 Twin Otter and Beechcraft B200 Super King Air. Uses Uses include aerial surveying, such as monitoring pipelines, light cargo operations, such as "feeding" cargo hubs, and passenger operations. Light aircraft are used for marketing purposes, such as banner towing and skywriting, and flight instruction. The majority of personal aircraft are light aircraft, the most popular in history being the Cessna 172, and most popular in modern history being the Cirrus SR22 and Robinson R44. Larger light aircraft, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stall Strips
A stall strip is a small component fixed to the leading edge of the wing of an airplane to modify its aerodynamic characteristics.Crane, Dale: ''Dictionary of Aeronautical Terms'', third edition, page 487. Aviation Supplies & Academics, 1997. These stall strips may be necessary for the airplane to comply with type certification requirements. A stall strip typically consists of a small piece of material, usually aluminium, triangular in cross section and often 6-12 inches (15–30 cm) in length. It is riveted or bonded to the wing’s leading edge. Some airplanes have one stall strip on each wing. Some airplanes have only one stall strip on one wing. Operation A stall strip initiates flow separation on a region of the upper surface of the wing during flight at high angle of attack. This is typically to avoid a tendency to spin following a stall, or to improve the controllability of the airplane as it approaches the stall. A stall strip may be intended to alter the wing†...

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 ...

1960s United States Sport Aircraft
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 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. Events By place Roman Empire * Emperor Septimius Severus attempts to assassinate Clodius Albinus but fails, causing Albinus to retaliate militarily. * Emperor Septimius Severus captures and sacks Byzantium; the city is rebuilt and regains its previous prosperity. * In order to assure the support of the Roman legion in Germany on his march to Rome, Clodius Albinus is declared Augustus by his army while crossing Gaul. * Hadrian's wall in Britain is partially destroyed.

Bede Aircraft
Bede Aircraft Corporation was founded by aeronautical engineer Jim Bede in Cleveland in 1961 to produce the BD-1 kit aircraft, which eventually became the American Aviation Corporation's AA-1. The company also created and produced a number of advanced kit planes including the famous Bede BD-5 (pusher propeller driven) and BD-5J (turbojet driven). The BD-5J has held the Guinness record as the World's Smallest Jet Aircraft for more than a quarter century. Versions of it saw use in various Budweiser commercials (the Bud Light Jet, which was lost in an inflight fire and crash unrelated to airshow work). The tiny jet also appeared in two James Bond movies; ''Octopussy'' starring Sir Roger Moore, and later in a cameo appearance, hanging from the wall of Q's workshop in ''Die Another Day'' starring Pierce Brosnan as Agent 007. A later design, the BD-10 powered by the same engine ( GE J-85) used on Lear Jet business jets, claimed to be the first supersonic personal jet built fro ...

Thorp T-211
The T-211 is a light aircraft designed in the US by John Thorp in 1945. It is a low-wing monoplane of conventional layout with fixed tricycle undercarriage and a sliding canopy. John Thorp developed the Sky Scooter with lessons learned from developing the Lockheed Little Dipper project in 1944. It bears some family resemblance to the Piper Cherokee, a design that Thorp later contributed to significantly. Development Thorp constructed eight prototypes, and had the design certified by the FAA, but was unable to find a foothold in the Cessna-dominated post-war US market. The original prototypes were powered by a 65 hp Lycoming engine. Novel features of the Sky Skooter include an all movable horizontal stabilizer and externally ribbed wings and tailplane. The wings were corrugated to impart stiffness, each wing needing only three internal ribs. This feature simplified construction, reduced the number of rivits (and weight), and helped control the spanwise flow of air over the wings ...

Van's Aircraft RV-6
The Van's RV-6 and RV-6A are two-seat, single-engine, low-wing homebuilt airplanes sold in kit form by Van's Aircraft. The RV-6 is the tail-wheel equipped version while the RV-6A features a nose-wheel. The RV-6 was the first aircraft in the popular Van's RV series to feature side-by-side seating and the first to offer a nosewheel option. It was first flown in 1985. Over 2700 kits have been completed and flown. The RV-6 and RV-6A were replaced by the similar, but improved, RV-7 in 2001. Kit components are still available to allow builders to complete RV-6s under construction, but no new complete kits are available. Development Van's Aircraft designer, Richard VanGrunsven, designed the RV-6 series as a two-seat side-by-side development of the RV-4, which was itself a development of the single seat RV-3. Market demand motivated VanGrunsven to design the RV-6 and offer it as an optional nosewheel design. The original two seater RV-4 has been a remarkable success, but ...

Flat-four
A flat-four engine, also known as a horizontally opposed-four 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 an inline-four engine. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasionally been used in motorcycles and frequently in aircraft. Cessna and Piper use flat four engines from Lycoming and Continental in the most common civil aircraft in the world - the Cessna 172, and Piper Cherokee, while many ultralight and LSA planes use versions of the Rotax 912. Design Most flat-four engines are designed so that each pair of opposing pistons moves inwards and o ... [...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 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 experiencing fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
