Channel Wing
The channel wing is an aircraft wing principle developed by Willard Ray Custer in the 1920s. The most important part of the wing consists of a half-tube with an engine placed in the middle, driving a propeller placed at the rear end of the channel formed by the half-tube. Development In 1925, Willard Custer had himself observed how very strong winds had managed to lift the roof of a barn. Custer realized that the high velocity of the wind created a lower pressure above the roof while the pressure remained high inside, literally blowing the roof off. This low pressure above/high pressure below is the same phenomenon that allows an airplane wing to provide lift even though in this case the barn itself was obviously not moving. Custer studied the phenomenon, and by 1928 he had made the first models of a wing with a half-tube-formed section instead of the usual wing profile. This was patented in 1929. Development of the half-tube channel wing was then refined further, and on No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aviation Week
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960. Other titles the magazine has held include ''Aviation & Aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AIAA
The American Institute of Aeronautics and Astronautics (AIAA) is a professional society for the field of aerospace engineering. The AIAA is the U.S. representative on the International Astronautical Federation and the International Council of the Aeronautical Sciences. In 2015, it had more than 30,000 members among aerospace professionals worldwide (a majority are American and/or live in the United States). History The AIAA was founded in 1963 from the merger of two earlier societies: the American Rocket Society (ARS), founded in 1930 as the American Interplanetary Society (AIS), and the Institute of the Aerospace Sciences (IAS), founded in 1932 as the Institute of the Aeronautical Sciences. Paul Johnston was the first executive director of the organization. Jim Harford took his seat after 18 months. The newly-formed structure gathered 47 technical committees and one broad technical publication, the ''AIAA Journal''. The ''AIAA Student Journal'' was also launched in 1963. Th ...

Popular Mechanics
''Popular Mechanics'' (sometimes PM or PopMech) is a magazine of popular science and technology, featuring automotive, home, outdoor, electronics, science, do-it-yourself, and technology topics. Military topics, aviation and transportation of all types, space, tools and gadgets are commonly featured. It was founded in 1902 by Henry Haven Windsor, who was the editor and—as owner of the Popular Mechanics Company—the publisher.

Oleg Antonov (aircraft Designer)
Oleg Konstantinovich Antonov (russian: Оле́г Константи́нович Анто́нов; 7 February 1906 – 4 April 1984) was a Soviet aeroplane designer, and the founder of the Antonov Design Bureau (located in Kyiv, Ukraine), named in his honour. Antonov designed a number of Soviet aeroplanes (such as the Antonov An-2, Antonov An-12) and numerous gliders for both civilian and military use. Early life Antonov was born on 7 February 1906 in Troitsy, Moscow Governorate, Russian Empire (now Podolsky District of the Moscow Oblast), Russian Empire to a family of Russian ethnicity. In 1912, the Antonovs moved to Saratov, where he attended the non-classical secondary school (now gymnasium №1) and secondary school (now school №23). From an early age, Antonov was fascinated with aviation and spent much of his spare time at the local airfield. Early engineering career At the age of 17, Antonov founded the "Amateur Aviation Club" and later joined the "Organization o ...

Antonov 181
Antonov built product 181 ( ukr, Виріб 181, rus, изделие 181) was a Soviet experimental aeroplane rolled-out at the end of the 1980s. History The Antonov An-181 (or product 181) project was terminated due to the lack of funds following the collapse of the Soviet Union. An interesting feature of the plane is its unusual arc-shaped wing, a so-called Channel wing The channel wing is an aircraft wing principle developed by Willard Ray Custer in the 1920s. The most important part of the wing consists of a half-tube with an engine placed in the middle, driving a propeller placed at the rear end of the cha .... The aircraft has two seats next to each other, a tricycle fixed landing gear configuration, a V-tailplane, and high-wing equipped with a channel wing in the area of the propellers. Power from the engine is delivered by means of drive shafts and deflection gearboxes to the two-blade propellers. The aircraft received the registration СССР-190101 and is exhibite ...

Rhein-Flugzeugbau RF-1
The Rhein-Flugzeugbau RF-1 was a prototype channel wing aircraft. Design and development The RF-1 is a modification of the channel wing concept, that uses a single channel and propeller to eliminate the asymmetrical lift issues with a twin channel wing design. The "channel" is an airfoil-shaped section along the lower arc of the rearward propeller that produces additional lift from the propwash. The RF-1's propeller was completely shrouded, creating a hybrid ducted propeller. Twin engine redundancy is maintained with multiple engines driving a central propeller with freewheeling clutches to allow for an engine failure. The aircraft had the unique shape to facilitate a channel wing design. The fuselage was composed of welded steel tubing with a composite skin. The landing gear Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Custer CCW-5
The Custer CCW-5 was a twin-engined, 5-seat aircraft of pusher configuration, which used a channel wing claimed to enable low speed flight and short take-offs. Two CCW-5s flew, eleven years apart, but the type never entered production. The aircraft was the third and last of a series of Custer Channel Wing designs. Design and development In most situations an aircraft's lift comes chiefly from the low pressure generated on the upper surface by the locally enhanced higher air velocity. This latter may be the result of the movement of the aircraft through the air or, when lift at low air speeds is important for short take-off performance, produced by engine power. The channel wing, the brainchild of Willard Ray Custer, is an example of the latter, where the air velocity over the upper surface velocity in a U-shaped channel formed out of the wing was increased with a pusher propeller at the trailing edge. This near semi-circular channel laterally constrained the airflow produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coandă Effect
The Coandă effect ( or ) is the tendency of a fluid jet to stay attached to a convex surface. ''Merriam-Webster'' describes it as "the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops." It is named after Romanian inventor Henri Coandă, who was the first to recognize the practical application of the phenomenon in aircraft design around 1910. It was first documented explicitly in two patents issued in 1936. Discovery An early description of this phenomenon was provided by Thomas Young in a lecture given to The Royal Society in 1800: A hundred years later, Henri Coandă identified an application of the effect during experiments with his Coandă-1910 aircraft, which mounted an unusual engine he designed. The motor-driven turbine pushed hot air rearward, and Coandă noticed that the airflow was attracted to nearby surfaces. In 1934 Coandă ...
