V-1570
The Curtiss V-1570 Conqueror was a 12-cylinder V12 engine, vee liquid-cooled aircraft engine. Representing a more powerful version of the Curtiss D-12, the engine entered production in 1926 in aviation, 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 Engine displacement, displacement of 1,570 cubic inches (26 L). The engine featured open-ended cylinder liners (advanced technology for the period) and pressurized Radiator (engine cooling), 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 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.

Douglas Y1B-7
The Douglas Y1B-7 was a 1930s American bomber aircraft. It was the first US monoplane given the ''B-'' 'bomber' designation. The monoplane was more practical and less expensive than the biplane, and the United States Army Air Corps chose to experiment with monoplanes for this reason. At the time the XB-7 was ordered, it was being tested by Douglas Aircraft as an observational plane. Design and development In 1929–1930, the Douglas Aircraft Company designed a new twin-engined monoplane observation aircraft to compete with the Fokker XO-27, two prototypes of which had been ordered by the United States Army Air Corps in July 1929, as Douglas feared that the advanced Fokker would challenge Douglas's role as the major supplier of observation aircraft to the Air Corps. The Douglas proposals resulted in the Air Corps placing an order for two prototypes, the XO-35 and XO-36, on 26 March 1930. The two aircraft were to differ only in the engines fitted, with the XO-35 having geared Curt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtiss P-6 Hawk
The Curtiss P-6 Hawk is an American single-engine biplane fighter introduced into service in the late 1920s with the United States Army Air Corps and operated until the late 1930s prior to the outbreak of World War II. Design and development The Curtiss Aeroplane and Motor Company (which became the Curtis-Wright Corporation (15 July 1929) supplied the USAAC with P-6s beginning in 1929. Operational history A fast and highly maneuverable aircraft for its time, the XP-6 prototype took 2nd place in the 1927 U.S. National Air Races, and the XP-6A with wing surface radiators took first place, at 201 mph (323 km/h). The P-6 was flown in a variety of paint schemes depending on the squadron, the most famous being the "Snow Owl" markings of the 17th Pursuit Squadron based at Selfridge Field near Detroit, Michigan. The P-6Es served between 1932 and 1937 with the 1st Pursuit Group (17th and 94th PS) at Selfridge, and with the 8th Pursuit Group (33rd PS) at Langley Field, Vi ...

Consolidated A-11
The Consolidated P-30 (PB-2) was a 1930s United States two-seat fighter aircraft. An attack version called the A-11 was also built, along with two Y1P-25 prototypes and YP-27, Y1P-28, and XP-33 proposals. The P-30 is significant for being the first fighter in United States Army Air Corps service to have retractable landing gear, an enclosed and heated cockpit for the pilot, and an exhaust-driven Turbocharger, turbo-supercharger for altitude operation. Design and development In 1931, the Detroit Aircraft Corporation, parent company of the Lockheed Corporation, Lockheed Aircraft Company built a two-seat single-engined fighter aircraft based on the Lockheed Altair high-speed transport as a private venture. The prototype, the Detroit-Lockheed XP-900, flew in September 1931 and was purchased by the United States Army Air Corps as the Lockheed YP-24. Its performance was impressive, being faster than any fighter then in service with the Air Corps, and an order for five Y1P-24 fighters a ...

Boeing Y1B-9
The Boeing YB-9 was the first all-metal monoplane bomber aircraft designed for the United States Army Air Corps. The YB-9 was an enlarged alteration of Boeing's Model 200 Monomail commercial transport. Design and development In May 1930, Boeing had flown its Model 200 Monomail single-engined mailplane. The Monomail was of radical design for the time, being a semi-monocoque, stressed skin cantilever monoplane with a retractable undercarriage. Air Corps bomber squadrons of the day were largely equipped with slow strut-braced biplanes built from steel-tube frames covered in doped fabric, such as the Keystone B-6, and Boeing decided to design and build a twin-engined bomber using the same techniques used in the Monomail to re-equip the Air Corps.Pelletier 2002, p. 44.Swanborough and Bowers 1963, p. 72. Using its own money, Boeing decided to build two prototypes of its new bomber design as a private venture. The two aircraft differed only in the engines used, with the Model 214 t ...

Curtiss A-8
The Curtiss A-8 was a low-wing monoplane ground-attack aircraft built by the United States company Curtiss Aeroplane and Motor Company, designed in response to a 1929 United States Army Air Corps requirement for an attack aircraft to replace the A-3 Falcon. The Model 59 "Shrike" was designated XA-8 (the "Shrike" nickname was not officially adopted). Development The XA-8 won a competition against the General Aviation/Fokker XA-7, after which 13 service test aircraft were ordered (five as YA-8s and eight as Y1A-8s). After the completion of testing, 11 of these aircraft were redesignated A-8. The A-8 was the first Curtiss machine of all-metal low-wing monoplane configuration with advanced features such as automatic leading edge slats and trailing-edge flaps. Four forward-firing .30 in (7.62 mm) machine guns were mounted in the wheel fairings, and an additional weapon of the same calibre was fitted in the observer's cockpit for rear defense. The standard bomb load was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berliner-Joyce P-16
The Berliner-Joyce P-16 was a 1930s United States two-seat fighter aircraft produced by Berliner-Joyce Aircraft Corporation. Design and development The Berliner-Joyce Aircraft Corporation was established in February 1929 when it acquired the assets of the Berliner Aircraft Company. The new company had intended to develop the Berliner Monoplane but became involved in designing a two-seat fighter for the United States Army Air Corps. The prototype, designated the Berliner-Joyce XP-16 first flew in October 1929 (at this time in the United States, fighter aircraft were known as "pursuit planes", and were designated with a "P"; the "X" stands for "Experimental"). It had a metal structure with a fabric covering. It was a single-bay biplane of unequal span ("sesquiplane"), with the wings forward-staggered. The lower wing was smaller than the upper and was mounted at the base of the fuselage, and unusually, were of reverse-gullwing type, while the upper wing was of gull wing configurati ...

Douglas 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.

Dornier Do X
The Dornier Do X was the largest, heaviest, and most powerful flying boat in the world when it was produced by the Dornier company of Germany in 1929. First conceived by Claude Dornier in 1924, planning started in late 1925 and after over 240,000 work-hours it was completed in June 1929. Dornier Museum, 45 seconds During the years between the two World Wars, only the Soviet Tupolev ANT-20 ''Maksim Gorki'' landplane of a few years later was physically larger, but at 53 metric tonnes maximum takeoff weight it was not as heavy as the Do X's 56 tonnes. The Do X was financed by the German Transport Ministry and in order to circumvent conditions of the Treaty of Versailles, which forbade any aircraft exceeding set speed and range limits to be built by Germany after World War I, a specially designed plant was built at Altenrhein, on the Swiss side of Lake Constance. The type was popular with the public, but a lack of commercial interest and a number of non-fatal accidents prevente ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtiss XP-10
The Curtiss XP-10 was an American experimental biplane fighter developed by Curtiss and tested by the United States Army Air Corps, but rejected due to disappointing performance and major problems with the cooling system. Design and development Ordered on 18 June 1928, it was intended to be fast and maneuverable enough to win a dogfight. The XP-10 used a gull wing top wing, joined at the fuselage; this offered much better pilot visibility than the traditional biplane configuration. Coincidentally, this also permitted the wing and fuselage to meet at the optimum angle for minimizing drag.Green 1973, p. 188. The wings were plywood-covered (rather than doped fabric, as used in World War I), and the fuselage was fabric-covered steel tubing. The XP-10 used a 600 hp (447 kW) Curtiss V-1570-15 Conqueror water-cooled V12 engine. To overcome the drag of a radiator (a quite serious issue before the introduction of ethylene glycol), Curtiss incorporated it into the upper wing ...

Curtiss P-1 Hawk
The P-1 Hawk (Curtiss Model 34) was a 1920s open-cockpit biplane fighter aircraft of the United States Army Air Corps. An earlier variant of the same aircraft had been designated PW-8 prior to 1925."US Military Aircraft Designations & Serials 1909-1979 by J.M. Andrade, (Midland Counties Publications, ) 1970, 252pp. Design and development PW-8 The Curtiss P-1 Hawk was the first US Army Air Service aircraft to be assigned the "P" (Pursuit) designation which replaced seven designations for pursuit aircraft, including "PW" (for "Pursuit, Water-cooled engine"). The P-1 was the production version of the Curtiss XPW-8B, an improved variant of the PW-8, 25 of which were operational with the Air Service's 17th Pursuit Squadron In September 1923, the Army ordered production of the PW-8. The PW-8 (Curtiss Model 33) had been developed from the R-6 racer and was acquired by the Air Service after a competition with the Boeing Model 15, designated the PW-9, to replace the existing Army f ...
