OS2U
The Vought OS2U Kingfisher is an American catapult-launched observation floatplane. It was a compact mid-wing monoplane, with a large central float and small stabilizing floats. Performance was modest because of its low-powered engine. The OS2U could also operate on fixed, wheeled, taildragger landing gear. The OS2U was the main shipboard observation seaplane used by the United States Navy during World War II, and 1,519 of the aircraft were built. It served on battleships and cruisers of the US Navy, with the United States Marine Corps in Marine Scouting Squadron Three (VMS-3), with the United States Coast Guard at coastal air stations, at sea with the Fleet Air Arm of the Royal Navy, and with the Soviet Navy. The Royal Australian Air Force also operated a few Kingfishers from shore bases. The Naval Aircraft Factory OS2N was the designation of the OS2U-3 aircraft built by the Naval Aircraft Factory in Philadelphia, Pennsylvania. The OS2U first flew on 1 March 1938. Design an ...

Observation Seaplane
Observation seaplanes are military aircraft with flotation devices allowing them to land on and take off from water. Their primary purpose was to observe and report enemy movements or to spot the fall of shot from naval artillery, but some were armed with machineguns or bombs. Their military usefulness extended from World War I through World War II. They were typically single-engine machines with catapult-launch capability and a crew of one, two or three. Most were designed to be carried aboard warships, but they also operated from seashore harbors. Purpose and history As the range of dreadnought battleship guns exceeded the distance from which shipboard personnel could observe shell splashes, observation aircraft were employed to: * locate targets * observe fall of shot for trajectory correction of large caliber naval artillery, and * assess damage to enemy ships. Wartime experience following the 1916 Battle of Jutland indicated additional usefulness for: * directing submarines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1938 In Aviation
This is a list of aviation-related events from 1938: Events * Imperial Airways inaugurates scheduled service from London to Montreal. Pan American World Airways is banned from British airports out of fears that more advanced U.S. aircraft will drive Imperial out of the transatlantic market. * The National Trophy, the Harmon Trophy presented to the outstanding aviator for the year in each of the 21 member countries of the International League of Aviators, is awarded for the last time, although the annual award of the Harmon Trophy to the worlds outstanding aviator, aviatrix (female aviator), and aeronaut (balloon or dirigible aviator or aviatrix) continues. * The Imperial Japanese Navys air arm conducts a six-month bombing campaign against Hankow and other centers of Chinese resistance in central China. * The Civil Aeronautics Authority is established in the United States and takes over operation of the air traffic control system. * The Spanish Republicans attempt to develop an ...

Vought
Vought was the name of several related American aerospace firms. These have included, in the past, Lewis and Vought Corporation, Chance Vought, Vought-Sikorsky, LTV Aerospace (part of Ling-Temco-Vought), Vought Aircraft Companies, and Vought Aircraft Industries. The first incarnation of Vought was established by Chance M. Vought and Birdseye Lewis in 1917. In 1928, it was acquired by United Aircraft and Transport Corporation, which a few years later became United Aircraft Corporation; this was the first of many reorganizations and buyouts. During the 1920s and 1930s, Vought Aircraft and Chance Vought specialized in carrier-based aircraft for the United States Navy, by far its biggest customer. Chance Vought produced thousands of planes during World War II, including the F4U Corsair. Vought became independent again in 1954, and was purchased by Ling-Temco-Vought (LTV) in 1961. The company designed and produced a variety of planes and missiles throughout the Cold War. Vought wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spoiler (aeronautics)
In aeronautics, a spoiler (sometimes called a lift spoiler or lift dumper) is a device which intentionally reduces the lift (force), lift component of an airfoil in a controlled way. Most often, spoilers are plates on the top surface of a wing that can be extended upward into the airflow to ''spoil'' the streamline flow. By so doing, the spoiler creates a controlled Stall (flight), stall over the portion of the wing behind it, greatly reducing the lift of that wing section. Spoilers differ from air brake (aeronautics), airbrakes in that airbrakes are designed to increase drag without disrupting the lift distribution across the wing span, while spoilers disrupt the lift distribution as well as increasing drag. Spoilers fall into two categories: those that are deployed at controlled angles during flight to increase descent rate or control roll, and those that are fully deployed immediately on landing to greatly reduce lift ("lift dumpers") and increase drag. In modern fly-by- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fleet Air Arm
The Fleet Air Arm (FAA) is one of the five fighting arms of the Royal Navy and is responsible for the delivery of naval air power both from land and at sea. The Fleet Air Arm operates the F-35 Lightning II for maritime strike, the AW159 Wildcat and AW101 Merlin for commando and anti-submarine warfare and the BAE Hawk as an aggressor. The Fleet Air Arm today is a predominantly rotary force, with helicopters undertaking roles once performed by biplanes such as the Fairey Swordfish. The Fleet Air Arm was formed in 1924 as an organisational unit of the Royal Air Force, which was then operating the aircraft embarked on RN ships—the Royal Naval Air Service having been merged with the Army's Royal Flying Corps in 1918 to form the Royal Air Force—and did not come under the direct control of the Admiralty until mid-1939. During the Second World War, the Fleet Air Arm operated aircraft on ships as well as land-based aircraft that defended the Royal Navy's shore establishments a ...

Philadelphia, Pennsylvania
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia. Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's inde ...

Spot Welding
A spot welder Spot welding (or resistance spot welding) is a type of electric resistance welding used to weld various sheet metal products, through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current. The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the thickness range. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a large amount of energy can be delivered to the spot in a very short time (approximately 10–100 milliseconds). This permits the welding to occur without excessive heating of the remainder of the sheet. The amount of heat (energy) delivered to the spot is determined by the resistance between the electrodes and the magnitude a ...

Aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Bou ...

Flap (aeronautics)
A flap is a high-lift device used to reduce the stall (flight), stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in Drag (physics), drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the Stall (fluid dynamics), stall of the outboa ... [...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 ...
