O-43
The Douglas O-43 was a monoplane observation aircraft used by the United States Army Air Corps. Development Five Y1O-31A service-test aircraft were ordered in 1931, and delivered to the USAAC in early 1933 designated Y1O-43. They differed from the final configuration of the O-31A, with a wire-braced parasol wing, and a new fin and rudder. An order for 23 O-43A aircraft was completed during 1934, with a deepened fuselage, which eliminated the need for the ventral bulge under the observer's position. Powered by a single 675 hp Curtiss V-1570-59 inline engine, it also had taller vertical surfaces with an inset rudder similar to the O-31A. The canopy was enlarged, and fully enclosed both cockpits. The O-43 and O-43A served with the USSAC observation squadrons for several years before being assigned to National Guard units,"The Complete Encyclopedia of World AircraftcoverEditors: Paul Eden & Soph Moeng, (Amber Books Ltd.

Douglas O-46
The Douglas O-46 was an observation aircraft used by the United States Army Air Corps and the Philippine Army Air Corps."Douglas Aircraft Builds the DC-1 and DC-2." ''U.S. Centennial of Flight Commission,'' 2003. Retrieved: 27 September 2007. Design and development The O-46A, the last of a long line of Douglas observation aircraft, was a victim of progress. It was designed to operate from established airfields behind fairly static battle lines as in . However, in 1939, a report was issued on the O-46A which stated that it was too slow and heavy to outrun and outmaneuver enemy fighter aircraft, too heavy to operate from small, w ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas O-31
The Douglas O-31 was the Douglas Aircraft Company's first monoplane observation straight-wing aircraft used by the United States Army Air Corps. Development Anxious to retain its position as chief supplier of observation aircraft to the USAAC, Douglas developed a proposal for a high-wing monoplane successor to the O-2. A contract was signed on January 7, 1930 for two XO-31 prototype aircraft, the first of them being flown in December of the same year. A fabric-covered gull-wing monoplane, the XO-31 had a slim corrugated dural-wrapped fuselage, similar to the Thomas-Morse O-19,"United States Military Aircraft Since 1909" by F. G. Swanborough & Peter M. Bowers (Putnam New York, ) 1964, 596 pp. carrying a tandem arrangement of open cockpits for the pilot and observer. It had one Curtiss GIV-1570-FM Conqueror V-12 engine and fixed landing gear with provision for large wheel fairings."The Complete Encyclopedia of World AircraftcoverEditors: Paul Eden & Soph Moeng, (Amber Books Ltd.

111th Observation Squadron
The 111th Attack Squadron (111 ATKS) is a unit of the Texas Air National Guard 147th Attack Wing located at Ellington Field Joint Reserve Base, Houston, Texas. The 111th is equipped with the General Atomics MQ-9 Reaper unmanned aerial vehicle (UAV). The squadron is a descendant organization of the World War I 111th Aero Squadron, established on 14 August 1917. It was reformed on 29 June 1923, as the 111th Observation Squadron, and is one of the 29 original National Guard Observation Squadrons of the United States Army National Guard formed before World War II. The 111th Attack Squadron is the oldest unit of the Texas Air National Guard, with over 95 years of service to the State of Texas and the United States.

Curtiss V-1570-59 Conqueror
The Curtiss V-1570 Conqueror was a 12-cylinder vee liquid-cooled aircraft engine. Representing a more powerful version of the Curtiss D-12, the engine entered production in 1926 and flew in numerous aircraft.Gunston 1989, p. 46. Design and development Designed in 1924 as a military successor to the Curtiss D-12, initially named the Conqueror, it was later given the military designation of V-1570 based on its displacement of 1,570 cubic inches (26 L). The engine featured open-ended cylinder liners (advanced technology for the period) and pressurized liquid cooling. Developments including the use of a supercharger gradually increased power output until reliability problems due to overheating and coolant leaks became apparent. Military funding for further development of the Conqueror was cut in 1932, efforts by Curtiss to market the engine for civil airliners failed and the line was dropped from production.

Douglas Aircraft Company
The Douglas Aircraft Company was an American aerospace manufacturer based in Southern California. It was founded in 1921 by Donald Wills Douglas Sr. and later merged with McDonnell Aircraft in 1967 to form McDonnell Douglas; it then operated as a division of McDonnell Douglas. McDonnell Douglas later merged with Boeing in 1997. History 1920s The company was founded as the Douglas Company by Donald Wills Douglas Sr. on July 22, 1921 in Santa Monica, California, following dissolution of the Davis-Douglas Company. An early claim to fame was the first circumnavigation of the world by air in Douglas airplanes in 1924. In 1923, the U.S. Army Air Service was interested in carrying out a mission to circumnavigate the Earth for the first time by aircraft, a program called "World Flight". Donald Douglas proposed a modified Douglas DT to meet the Army's needs. The two-place, open cockpit DT biplane torpedo bomber had previously been produced for the U.S. Navy.Rumerman, Judy.
