Henry Berliner
Henry Adler Berliner (December 13, 1895 – May 1, 1970) was a United States aircraft and helicopter pioneer. Sixth son of inventor Emile Berliner, he was born in Washington, D.C. He studied mechanical engineering at Cornell University for two years before attending Massachusetts Institute of Technology. After a short time as aerial photographer with the Army Air Service, in 1919 Henry moved back to Washington to help his father with the helicopter research that had been underway for many years (since 1903 New International Encyclopedia). Using a Le Rhône engine of 80 hp mounted on a test stand, Henry was able to hover and move forward, but only with assistants holding on to stabilize the contraption. In 1922, he bought a surplus Nieuport 23 fighter's fuselage, added a Bentley 220 hp engine on the front, and connected it by geared shafts to two horizontal rotors mounted on a truss extending sideways from the fuselage. A third horizontal rotor at the rear provided pit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monoplanes
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 ...

Berliner Helicopter
The Berliner Helicopter was a series of experimental helicopters built by Henry Berliner between 1922 and 1925. The helicopters had only limited controllability but were the most significant step forward in helicopter design in the US, until the production of the Vought-Sikorsky VS-300 helicopter in 1940. The 1922 flights of the Berliner and the de Bothezat H1 were the first by manned helicopters.''The Helicopter: A Hundred Years of Hovering'' Wired.com.

PB4Y-2 Privateer
The Consolidated PB4Y-2 Privateer is an American World War II and Korean War era patrol bomber of the United States Navy derived from the Consolidated B-24 Liberator. The Navy had been using B-24s with only minor modifications as the PB4Y-1 Liberator, and along with maritime patrol Liberators used by RAF Coastal Command this type of patrol plane was proven successful. A fully navalised design was desired, and Consolidated developed a dedicated long-range patrol bomber in 1943, designated PB4Y-2 Privateer.Baugher, Joe"Convair PB4Y-2 Privateer."''American Military Aircraft,'' 23 August 1999. Retrieved: 13 November 2010. In 1951, the type was redesignated P4Y-2 Privateer. A further designation change occurred in September 1962, when the remaining Navy Privateers (all having previously been converted to drone configuration as P4Y-2K) were redesignated QP-4B. Design and development The Privateer was externally similar to the Liberator, but the fuselage was longer to accommodate a f ...

PB4Y-1 Liberator
The Consolidated B-24 Liberator is an American heavy bomber, designed by Consolidated Aircraft of San Diego, California. It was known within the company as the Model 32, and some initial production aircraft were laid down as export models designated as various LB-30s, in the Land Bomber design category. At its inception, the B-24 was a modern design featuring a highly efficient shoulder-mounted, high aspect ratio Davis wing. The wing gave the Liberator a high cruise speed, long Range (aeronautics), range and the ability to carry a heavy Aerial bomb, bomb load. Early Royal Air Force, RAF Liberators were the first aircraft to cross the Atlantic Ocean as a matter of routine. In comparison with its contemporaries, the B-24 was relatively difficult to fly and had poor low-speed performance; it also had a lower Ceiling (aeronautics), ceiling and was less robust than the Boeing B-17 Flying Fortress. While Aircrew#Military, aircrews tended to prefer the B-17, General Staff favored the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ball Turret
A ball turret was a spherical-shaped, altazimuth mount gun turret, fitted to some American-built aircraft during World War II. The name arose from the turret's spherical housing. It was a manned turret, as distinct from remote-controlled turrets also in use. The turret held the gunner, two heavy machine guns, ammunition, and sights. The Sperry Corporation designed ventral versions that became the most common version; thus, the term "ball turret" generally indicates these versions. Sperry ball turret Sperry and Emerson Electric each developed a ball turret, and the designs were similar in the nose turret version. Development of the spherical Emerson was halted. The Sperry nose turret was tested and preferred, but its use was limited due to poor availability of suitable aircraft designs. The Sperry-designed ventral system saw widespread use and production, including much sub-contracting. The design was mainly deployed on the B-17 Flying Fortress and the B-24 Liberator, as we ...

ERCO Ercoupe
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 wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Logan Field (Maryland)
Logan Field, also known as Dundalk Flying Field, is a former airport located in the town of Dundalk, Maryland, northeast of the Francis Scott Key Bridge, near Baltimore. Name Although Logan Field was originally named the Dundalk Flying Field, it was almost immediately renamed. On July 5, 1920, Army Lt. Patrick H. Logan was fatally injured after his aircraft, a World War I vintage French Nieuport 28 nicknamed the "Red Devil," crashed at the field's inaugural air show. In response to the tragedy, the airfield was renamed in Logan's honor during the closing ceremonies of the air show during which he died. Facilities Logan Field consisted of three landing strips of turf-and-cinder construction: a 3,000-foot runway and two 2,000-foot runways. The field had a number of small clapboard buildings to handle passengers and mail, as well as simple hangar facilities, including military facilities for the Maryland National Guard's 104th Observation Squadron.

Dundalk, Maryland
Dundalk ( or ) is an unincorporated community and census-designated place in Baltimore County, Maryland, United States. The population was 67,796 at the 2020 census. In 1960 and 1970, Dundalk was the largest unincorporated community in Maryland. It was named after the town of Dundalk, Ireland. Dundalk is considered one of the first inner-ring suburbs of Baltimore. History The area now known as Dundalk was first explored by John Smith in 1608. Up until this time, the area had been occupied by the tribes of the Susquehannock. In 1856 Henry McShane, an immigrant from Ireland, established the McShane Bell Foundry on the banks of the Patapsco River in the then far southeastern outskirts of Baltimore. The foundry later relocated to the Patterson Park area of Baltimore until a fire during the 1940s caused it to move to 201 East Federal Street. In addition to bronze bells, the foundry once manufactured cast iron pipes and furnace fittings. When asked by the Baltimore and Sparro ...
