Buhl CA-1 Airster
The Buhl CA-1 Airster was a sports airplane developed in the United States in 1930. It was a conventional low-wing cantilever monoplane with fixed tailwheel undercarriage and an open cockpit for the pilot. The CA-1 was designed for air-racing and for use as a mail plane. No market was found for the aircraft and only the single prototype was ever constructed. A two-seat variant was developed with a second open cockpit in tandem with the pilot's and with a Townend ring A Townend ring is a narrow- chord cowling ring fitted around the cylinders of an aircraft radial engine to reduce drag and improve cooling.

Townend Ring
A Townend ring is a narrow- chord cowling ring fitted around the cylinders of an aircraft radial engine to reduce drag and improve cooling. Development The Townend ring was the invention of Dr. Hubert Townend of the British National Physical Laboratory in 1929. Patents were supported by Boulton & Paul Ltd in 1929. In the United States it was often called a "drag ring". It caused a reduction in the drag of radial engines and was widely used in high-speed designs of 1930–1935, before the long-chord NACA cowling came into general use. Despite suggestions of it exploiting the Meredith effect, low airspeeds, low temperature differences and small mass flows make that unlikely, particularly when combined with the lack of flow control as the air exits the cowling.Becker, J.; ''The high-speed frontier: Case histories of four NACA programs, 1920–1950'', SP-445, NASA (1980)Chapter 5: High-speed Cowlings, Air Inlets and Outlets, and Internal-Flow Systems: The ramjet investiga ...

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 a ...

Racing Aircraft
Air racing is a type of motorsport that involves airplanes or other types of aircraft that compete over a fixed course, with the winner either returning the shortest time, the one to complete it with the most points, or to come closest to a previously estimated time. History The first 'heavier-than-air' air race was held on 23 May 1909 - the Prix de Lagatinerie, at the Port-Aviation airport south of Paris, France. Four pilots entered the race, two started, but nobody completed the full race distance; though this was not unexpected, as the rules specified that whoever travelled furthest would be the winner if no-one completed the race. Léon Delagrange, who covered slightly more than half of the ten laps was declared the winner. Some other minor events were held before the '' Grande Semaine d'Aviation de la Champagne'' in 22–29 August 1909 at Reims, France. This was the first major international flying event, drawing the most important aircraft makers and pilots of the era ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1930s United States Sport Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.

Buhl-Verville CA-3 Airster
The Buhl-Verville CA-3 Airster (also known as the J4 Airster, after its engine), was a utility aircraft built in the United States in 1926, notable as the first aircraft to receive a type certificate in the US, (i.e. A.T.C. No. 1) issued by the Aeronautics Branch of the Department of Commerce on March 29, 1927. It was a conventional single-bay biplane with equal-span unstaggered wings and accommodation for the pilot and passengers in tandem open cockpits. Marketed for a variety of roles including crop-dusting, aerial photography, and freight carriage, only a handful were built, some with water-cooled engines as the CW-3, and others with air-cooled engines as the CA-3 . One CA-3 placed second in the 1926 Ford National Reliability Air Tour. 1926 Ford Air Tour, piloted by Louis Meister, and another (designated the CA-3A) placed third in the 1927 Air Derby, piloted by Nick Mamer.

Buhl Airsedan
The Buhl AirSedan was a family of American civil cabin sesquiplane aircraft developed and manufactured by the Buhl Aircraft Company in the late 1920s. One example completed the first transcontinental non-stop roundtrip flight, made in 1929 by the CA-6 ''Spokane Sun-God'', and the first Pope to have flown did so in a Buhl Airsedan. Design and development The Airsedan series were designed by Etienne Dormoy following the departure of Alfred V. Verville from Buhl, with whom he had worked previously. Dormoy had worked with Deperdussin before World War one, flew combat operations during the war before returning to work with SPAD, travelled to the US to coordinate production of SPADs with Curtiss until the project was cancelled with the end of the war. He then worked with Packard on automobiles for a year in 1919 before working as a civilian with the United States Army Air Corps with Verville, who convinced him to work at Buhl.Bleneau, Les berlines Buhl (Première partie), p.2- ...

Aircraft Fairing
An aircraft fairing is a structure whose primary function is to produce a smooth outline and reduce drag.Crane, Dale: ''Dictionary of Aeronautical Terms, Third Edition'', page 206. Aviation Supplies & Academics Inc, Newcastle Washington, 1997. These structures are covers for gaps and spaces between parts of an aircraft to reduce form drag and interference drag, and to improve appearance.Bingelis, Tony: ''The Sportplane Builder'', pages 261-265. Experimental Aircraft Association Aviation Foundation, 1979. Types On aircraft, fairings are commonly found on: ; Belly fairing : Also called a "ventral fairing", it is located on the underside of the fuselage between the main wings. It can also cover additional cargo storage or fuel tanks. ; Cockpit fairing : Also called a "cockpit pod", it protects the crew on ultralight trikes. Commonly made from fiberglass, it may also incorporate a windshield.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page C-17. Cy ...

Mail Plane
A mail plane is an aircraft used for carrying mail. Aircraft that were purely mail planes existed almost exclusively prior to World War II. Because early aircraft were too underpowered to carry cargoes, and too costly to run any "economy class" passenger-carrying service, the main civilian role for aircraft was to carry letters faster than previously possible. In 1934, some mail services in the USA were operated by the United States Army Air Corps, soon ending in the Air Mail scandal. In the past, mail-carrying aircraft had to carry a special official emblem on the fuselages; in case of British-registered aircraft, a special ''Royal Air Mail pennant'' (a blue triangular flag with a crowned bugle emblem in yellow and the letters "ROYAL AIR MAIL" in white) would sometimes be flown as well. From the late 1940s, mail planes became increasingly rare, as the increasing size of aircraft and economics dictated a move towards bulk carriage of mail onboard airline flights, and this rema ...

Cockpit
A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a pilot controls the aircraft. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin. After the September 11, 2001 attacks, all major airlines fortified their cockpits against access by hijackers. Etymology The word cockpit seems to have been used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore. The word "cockswain" in turn derives from the old English terms for "boat-servant" (''coque'' is the French word for "shell"; and ''swain'' was old English for boy or se ...
