Aeromarine PG-1
The Aeromarine PG-1 was an American single-seat pursuit (fighter) and ground attack (PG) biplane developed by the Engineering Division of the United States Army and manufactured by the Aeromarine Plane and Motor Co. Development and design The PG-1 was intended to fulfill both ground strafing and aerial defense roles, the contract for construction was won by Aeromarine in May 1921. Armed with a single 0.5 in (12.7 mm) machine gun as well as a 37 mm Baldwin cannon firing through the propeller hub; the cockpit had armour. The wings were dissimilar, with a wide-chord upper wing with ailerons, and a closely spaced narrow-chord lower plane with dihedral that placed the tips close to the upper wing. The upper wing was mounted close to the top of the fuselage with a cut-away forward section to accommodate the cockpit, and attached to the lower plane ''via'' V-type struts. Power was to have been provided by the eight-cylinder, water-cooled Wright K-2 engine but the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister 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'' 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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

PG-1 - Ray Wagner Photo Collection (16387189799)
The Explorer PG-1 Aqua Glider is an American single seat, biplane glider that was designed by Bill Skiliar in 1959 and made available as plans for amateur construction. The prototype was built with help from a troop of Air Explorer Scouts that same year.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 40. Soaring Society of America November 1983. USPS 499-920EAA AirVenture Museum, 2011, ''Skiliar Aqua Glider “Explorer” – N6498D'' http://www.airventuremuseum.org/collection/aircraft/Skliar Aqua Glider.asp, accessed 10 May 2011 Design and development Skiliar was a Colonel in the USAF and an aeronautical engineer and test pilot. He designed the Aqua Glider to be towed behind a boat, taking off from the water, releasing the tow rope and then gliding to a landing on the water. The Aqua Glider is made from wood and covered with doped aircraft fabric. The landing gear is fixed and consists of a pair of water skis. The aircraft uses spoilers instead of ailerons fo ...

McCook Field
McCook Field was an airfield and aviation experimentation station in Dayton, Ohio, United States. It was operated by the Aviation Section, U.S. Signal Corps and its successor the United States Army Air Service from 1917 to 1927. It was named for Alexander McDowell McCook, an American Civil War general and his brothers and cousins, who were collectively known as " The Fighting McCooks". History In 1917, anticipating a massive need for military airplanes by the United States during World War I, six Dayton businessmen including Edward A. Deeds formed the Dayton-Wright Company in Dayton, Ohio. In addition to building a factory in Moraine, Ohio, Deeds built an airfield on property he owned in Moraine for use by the company. Deeds was also interested in building a public aviation field along the Great Miami River approximately one mile (1.6 km) north of downtown Dayton, purchasing the property in March 1917. He called it North Field to differentiate it from the South Field in Mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Packard 1A-1237
Packard or Packard Motor Car Company was an American luxury automobile company located in Detroit, Michigan. The first Packard automobiles were produced in 1899, and the last Packards were built in South Bend, Indiana in 1958. One of the "Three Ps" alongside Peerless Motor Company, and Pierce-Arrowthe company was known for building high-quality luxury automobiles before World War II. Owning a Packard was considered prestigious, and surviving examples are found in museums, car shows, and automobile collections. Packard vehicles featured innovations, including the modern steering wheel, air-conditioning in a passenger car, and one of the first production 12-cylinder engines, adapted from developing the Liberty L-12 engine used during World War I to power warplanes. During World War II, Packard produced 55,523 units of the two-stage/two-speed supercharger equipped Merlin V-12s engines under contract with Rolls-Royce. Packard also made the versions of the Liberty L-12 V-12 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Piston Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intro ...

Curtiss-Wright
The Curtiss-Wright Corporation is a manufacturer and services provider headquartered in Davidson, North Carolina, with factories and operations in and outside the United States. Created in 1929 from the consolidation of Curtiss, Wright, and various supplier companies, the company was immediately the country's largest aviation firm and built more than 142,000 aircraft for the U.S. military during World War II. Today, it no longer makes aircraft but makes many related components, particularly actuators, aircraft controls, valves, and surface-treatment services. It also supplies the commercial, industrial, defense, and energy markets; it makes parts for commercial and naval nuclear power systems, industrial vehicles, and oil- and gas-related machinery. History Merger and expansion Curtiss-Wright formed on July 5, 1929, the result of a merger of 12 companies associated with Curtiss Aeroplane and Motor Company of Buffalo, New York, and Wright Aeronautical of Dayton, Ohio.

Vehicle Armour
Military vehicles are commonly armoured (or armored; see spelling differences) to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships. Civilian vehicles may also be armoured. These vehicles include cars used by officials (e.g., presidential limousines), reporters and others in conflict zones or where violent crime is common. Civilian armoured cars are also routinely used by security firms to carry money or valuables to reduce the risk of highway robbery or the hijacking of the cargo. Armour may also be used in vehicles to protect from threats other than a deliberate attack. Some spacecraft are equipped with specialised armour to protect them against impacts from micrometeoroids or fragments of space debris. Modern aircraft powered by jet engines usually have them fitted with a sort of armour in the form of an aramid composite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
