Engineering And Research Corporation
Engineering and Research Corporation (ERCO) was started by Henry Berliner in 1930. Berliner was the son of Emile Berliner, who had patented numerous inventions relating to sound and acoustics, and pioneer of helicopter development with the experimental Berliner Helicopter. The younger Berliner founded ERCO to produce tools for the manufacture of metal aircraft and propellers. He founded the company in a shed at 2014 5th Street NW Washington D.C. Berliner met Fred Weick, an aeronautical engineer, who worked with National Advisory Committee for Aeronautics in cowlings and propellers on a 1926 while developing the propellers for the USS Akron. Weick also worked on an experimental aircraft that incorporated the up-to-date safety features. In 1935, the company moved to 6100 Sligo Blvd. In 1936, Weick left NACA to work for ERCO on his "safety airplane". In 1937, Berliner purchased 50 acres of land in Riverdale, Maryland near the College Park Airport and built the large ERCO factor ...

Sanders Aviation
The ERCO Ercoupe is an American low-wing monoplane aircraft that was first flown in 1937. It was originally manufactured by the Engineering and Research Corporation (ERCO) shortly before World War II; several other manufacturers continued its production after the war. The final model, the Mooney M-10, first flew in 1968 and the last model year was 1970. It was designed to be the safest fixed-wing aircraft that aerospace engineering could provide at the time, and the type continues to enjoy a faithful following. Design and development Fred Weick In 1931, aeronautical engineer Fred Weick was assistant chief of the aeronautics division of the National Advisory Committee for Aeronautics (NACA). In 1934 he asked permission to build an aircraft based on the 1931 Stout Skycar, using fabric instead of aluminum covering, and control modifications based on NACA research. Weick and a group of co-workers designed and assembled the experimental aircraft with a group of his colleagues ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Turrets
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gun-mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Air And Space Museum
The National Air and Space Museum of the Smithsonian Institution, also called the Air and Space Museum, is a museum in Washington, D.C., in the United States. Established in 1946 as the National Air Museum, it opened its main building on the National Mall near L'Enfant Plaza in 1976. In 2018, the museum saw about 6.2 million visitors, making it the fifth-most-visited museum in the world, and the second-most-visited museum in the United States. In 2020, due to long closures and a drop in foreign tourism caused by the COVID-19 pandemic, museum attendance dropped to 267,000. The National Air and Space Museum is a center for research into the history and science of aviation and spaceflight, as well as planetary science and terrestrial geology and geophysics. Almost all spacecraft and aircraft on display are originals or the original backup craft. The museum contains the Apollo 11 Command Module ''Columbia'', the ''Friendship 7'' capsule which was flown by John Glenn, Charles Lin ...

Continental A-65
The Continental O-170 engine is the collective military designation for a family of small aircraft engines, known under the company designation of A50, A65, A75 and A80. The line was designed and built by Continental Motors commencing in the 1940s. It was employed as the powerplant for civil and military light aircraft.Christy (1983) The horizontally opposed, four-cylinder engines in this family are all identical in appearance, bore, stroke, dry weight, and piston displacement. All feature a bottom-mounted updraft carburetor fuel delivery system. The higher power variants differ only in compression ratio and maximum allowable rpm, plus minor modifications. The lower power versions are fully convertible to the higher rated versions. Design and development In all models of this family of engines the cylinder heads are of aluminum alloy, screwed and shrunk onto steel barrels. Spark plug inserts and intake valve seats are made from aluminum- bronze alloy, while the exhaust valve s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ERCO I-L 116
The ERCO IL-116 was an American Inline engine (aviation), inline aircraft engine designed and built in the late 1930s. The type was not placed into series production due to competition from cheaper engines. Design and development In late 1938 in aviation, 1938, the Engineering and Research Corporation (ERCO) searched unsuccessfully for a suitable engine for its new "safe" airplane, the Ercoupe. ERCO hired Harold Morehouse, former engineer in charge of small engine design at Continental Motors Company, Continental Motors, to design a new engine. He came up with the inverted, in-line IL-116, which provided good pilot visibility and enhanced aircraft streamlining. ERCO installed the IL-116 in the prototype Ercoupe Model 310 in 1939 in aviation, 1939. The engine performed well, but ERCO discontinued it when Continental introduced the Continental A65 engine in 1940 in aviation, 1940, which generated comparable horsepower at half the cost. ERCO manufactured parts for six IL-116s but on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
