Martin T3M
The Martin T3M was an American torpedo bomber of the 1920s. A single-engined three-seat biplane, it became a standard torpedo bomber of the U.S. Navy, operating from both land bases and from aircraft carriers from 1926 to 1932. Development and design Having built 75 examples of the Martin SC, the production version of the Curtiss CS in 1925, the Glenn L. Martin Company was able to offer an improved version when the U.S. Navy had a requirement for an improved torpedo-bomber/scout aircraft. This aircraft, which was designated the T3M-1, first flew in July 1926.Grossnick 1995, p.507. The T3M was a large single-engined biplane capable of being fitted with either a conventional tailwheel undercarriage or floats. The fuselage was constructed of welded steel tube in place of the riveted steel frame of the CS/SC,Martin T4M Naval Air Station Grosse Poin ...

V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and ...

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, which 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 ... [...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 with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers. The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as ...

Naval Aircraft Factory
The Naval Aircraft Factory (NAF) was established by the United States Navy in 1918 in Philadelphia, Pennsylvania. It was created to help solve aircraft supply issues which faced the Navy Department upon the entry of the U.S. into World War I. The US Army’s requirements for an enormous quantity of airplanes created a decided lack of interest among aircraft manufacturers in the Navy's requirements for a comparatively small quantity of aircraft. The Navy Department concluded that it was necessary to build a Navy-owned aircraft factory in order to assure a part of its aircraft supply; to obtain cost data for the department’s guidance in its dealings with private manufacturers; and to have under its own control a factory capable of producing experimental designs. History On 27 July 1917, Secretary of the Navy Josephus Daniels approved the construction of the Naval Aircraft Factory, as a means for the government to promote industry efficiency, ensure engineering expertise, and ...

Curtiss F6C And Martin T3m On Deck Of USS Lexington (CV-2), 1928
Curtiss Aeroplane and Motor Company (1909 – 1929) was an American aircraft manufacturer originally founded by Glenn Hammond Curtiss and Augustus Moore Herring in Hammondsport, New York. After significant commercial success in its first decades, it merged with the Wright Aeronautical to form Curtiss-Wright Corporation. History Origin In 1907, Glenn Curtiss was recruited by the scientist Dr. Alexander Graham Bell as a founding member of Bell's Aerial Experiment Association (AEA), with the intent of establishing an aeronautical research and development organization. According to Bell, it was a "co-operative scientific association, not for gain but for the love of the art and doing what we can to help one another."Milberry 1979, p 13. In 1909, shortly before the AEA was disbanded, Curtiss partnered with Augustus Moore Herring to form the Herring-Curtiss Company.Gunston 1993, p. 87. It was renamed the Curtiss Aeroplane Company in 1910 and reorganized in 1912 after being taken-o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...
