Martin T4m
The Martin T4M was an United States of America, American torpedo bomber of the 1920s. A development by the Glenn L. Martin Company of their earlier Martin T3M, and, like it a single-engined biplane, the T4M served as the standard torpedo bomber aboard the aircraft carriers of the United States Navy through much of the 1930s. Development and design The Martin Model 74 was designed and developed by the Glenn L. Martin Company as a result of testing of the experimental radial engine, radial-engined developments of the Martin T3M, the XT3M-3 and XT3M-4. The resulting prototype, designated XT4M-1, first flew in April 1927,Swanborough and Bowers 1976, p.311 and was purchased by the U.S. Navy for further evaluation.Grossnick 1995, p.508. The XT4M-1 had new single-bay fabric-covered metal wings of shorter span than the wooden wings of the T3M.Taylor 1981, p.93. It was powered by a Pratt & Whitney Hornet, (as used by the XT3M-3), and was fitted with a revised rudder. The fuselage was sim ...

A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Mitsubishi B2M
The Mitsubishi B2M was a Japanese carrier-based torpedo bomber of the 1920s and 1930s. It was built by Mitsubishi to a design by Blackburn Aircraft of Britain and was operated by the Imperial Japanese Navy. Design and development In 1927, the Japanese company Mitsubishi commissioned the British aircraft manufacturer Blackburn Aircraft to design an aircraft, which would be built under licence by Mitsubishi if successful, to enter a competition held by the Imperial Japanese Navy for a carrier-based reconnaissance and torpedo bomber to replace its B1M. Blackburn developed a design, the Blackburn T.7B, which was an enlarged development of their Ripon and was under development for Britain's Fleet Air Arm. The T.7B was a three-seat biplane of steel tube construction and with high aspect ratio wings fitted with Handley Page slats, powered by a 466 kW (625 hp) Hispano-Suiza 12Lbr engine. The design was declared the winner of the competition with a prototype (referred to as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackburn Ripon
The Blackburn T.5 Ripon was a carrier-based torpedo bomber and reconnaissance biplane designed and produced by the British aircraft manufacturer Blackburn Aircraft. It was the basis for both the license-produced Mitsubishi B2M and the improved Blackburn Baffin. The Ripon was designed as a successor to the Blackburn Dart torpedo bomber as well as a long-range reconnaissance aircraft to fulfil Air Ministry Specification 21/23. The first prototype made its maiden flight on 17 April 1926, it was subsequently redesigned with a more effective engine installation, an enlarged rudder and increased wing sweepback. It was originally ordered into production for the Fleet Air Arm (FAA), which primarily operated the type as a torpedo bomber. The Ripon was operated by the FAA between 1930 and 1935, after which point it was withdrawn in favour of the Blackburn Baffin, which was an improved derivative of the Ripon. It was also produced overseas in Finland; many of the Ripons in service ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtiss CS
The Curtiss CS (or Model 31) was a reconnaissance and torpedo bomber aircraft used by the United States Navy during the 1920s. It was a large single-engine biplane with single-bay unstaggered wings, the design conventional in all respects other than that the lower wing was of greater span than the upper. The CS was built to allow its undercarriage to be quickly and easily interchangeable between wheeled, tailskid undercarriage, and twin pontoons for operation from water. Provision for the carriage of a torpedo was semi-recessed into the underside of the fuselage, blended in behind an aerodynamic fairing. The pilot and gunner sat in tandem open cockpits, while accommodation inside the fuselage was provided for a third crewmember who served as bombardier and radio operator. This station was also provided with a dorsal hatch aft of the gunner's position, and a ventral blister aft of the torpedo recess, which was used for aiming bombs or torpedoes. Development Curtiss produced six CS- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wright R-1820
The Wright R-1820 Cyclone 9 is an American radial engine developed by Curtiss-Wright, widely used on aircraft in the 1930s through 1950s. It was produced under license in France as the Hispano-Suiza 9V or Hispano-Wright 9V, and in the Soviet Union as the Shvetsov M-25. Design and development The R-1820 Cyclone 9 represented a further development of the Wright P-2 engine dating back to 1925. Featuring a greater displacement and a host of improvements, the R-1820 entered production in 1931. The engine remained in production well into the 1950s. The R-1820 was built under license by Lycoming, Pratt & Whitney Canada, and also, during World War II, by the Studebaker Corporation. The Soviet Union had purchased a license for the design, and the Shvetsov '' OKB'' was formed to metricate the American specification powerplant for Soviet government-factory production as the '' M-25'', with the R-1820's general design features used by the Shvetsov design bureau for many of their futu ...

TBD Devastator
The Douglas TBD Devastator is a retired American torpedo bomber of the United States Navy. Ordered in 1934, it first flew in 1935 and entered service in 1937. At that point, it was the most advanced aircraft flying for the Navy, being the first metal monoplane in the United States Navy; however, by the time of the Attack on Pearl Harbor, US entry into World War 2, the TBD was already outdated. The Devastator performed well early in the war, most notably in the Battle of the Coral Sea, but earned infamy for a catastrophic performance during the Battle of Midway in which 41 Devastators recorded zero torpedo hits with only six surviving to return to their carriers. Although much of the Devastator's dismal performance was later attributed to the many well-documented defects in the US Mark 13 torpedo, the aircraft was withdrawn from frontline service after Midway, being replaced by the Grumman TBF Avenger.
