A-24 Dauntless
The Douglas SBD Dauntless is a World War II American naval scout plane and dive bomber that was manufactured by Douglas Aircraft from 1940 through 1944. The SBD ("Scout Bomber Douglas") was the United States Navy's main carrier-based scout/dive bomber from mid-1940 through mid-1944. The SBD was also flown by the United States Marine Corps, both from land air bases and aircraft carriers. The SBD is best remembered as the bomber that delivered the fatal blows to the Japanese carriers at the Battle of Midway in June 1942.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' pp. 25–34, Cypress, CA, 2013. . The type earned its nickname "Slow But Deadly" (from its SBD initials) during this period. During its combat service, the SBD proved to be an effective naval scout plane and dive bomber. It possessed long range, good handling characteristics, maneuverability, potent bomb load, great diving characteristics from the perforated dive b ...

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering carrier-based aircraft, shipborne aircraft. Typically it is the capital ship of a naval fleet, fleet (known as a carrier battle group), as it allows a naval force to power projection, project seaborne naval aviation, air power far from homeland without depending on local airfields for staging area, staging aerial warfare, aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear marine propulsion, nuclear-powered supercarriers that carry dozens of fighter aircraft, fighters, strike aircraft, military helicopters, airborne early warning and control, AEW&Cs and other types of aircraft such as unmanned combat aerial vehicle, UCAVs. While heavier fixed-wing aircraft such as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reconnaissance Aircraft
A reconnaissance aircraft (colloquially, a spy plane) is a military aircraft designed or adapted to perform aerial reconnaissance with roles including collection of imagery intelligence (including using Aerial photography, photography), signals intelligence, as well as measurement and signature intelligence. Modern technology has also enabled some aircraft and Unmanned aerial vehicle, UAVs to carry out real-time surveillance in addition to general Military intelligence, intelligence gathering. Before the development of devices such as radar, military forces relied on reconnaissance aircraft for visual Artillery observer, observation and Reconnaissance, scouting of enemy movement. An example is the Consolidated PBY Catalina, PBY Catalina Maritime patrol aircraft, maritime patrol flying boat used by the Allies of World War II, Allies in World War II: a Formation flying, flight of United States Navy, U.S. Navy Catalinas spotted part of the Japanese fleet approaching Midway Island ...

Self-sealing Fuel Tank
A self-sealing fuel tank (SSFT) is a type of fuel tank, typically used in aircraft fuel tanks or fuel bladders, that prevents them from leaking fuel and igniting after being damaged. Typical self-sealing tanks have layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber, which can absorb fuel when it comes into contact with it. When a fuel tank is punctured the fuel seeps into these layers, causing the untreated layer to swell, closing and thus sealing the puncture. A similar concept is also employed for making self-sealing run-flat tires. History World War I George J. Murdock applied for the patent "War Aeroplane Fuel Tanks" on February 7, 1917 but was temporarily blocked by an order of the Federal Trade Commission, on February 6, 1918, to keep any discussion or publication of the invention secret. The order was rescinded by the United States Patent Office on September 26, 1918 and Murdock was eventually granted "Self-Punctur ...

Vehicle Armour
Military vehicles are commonly armoured (or armored; American and British English spelling differences#-our, -or, see spelling differences) to withstand the impact of Fragmentation (weaponry), shrapnel, bullets, Shell (projectile), shells, Rocket (weapon), 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., Official state car, presidential limousines), reporters and others in conflict zones or where violent crime is common. Civilian Armored car (valuables), armoured cars are also routinely used by security firms to carry money or valuables to reduce the risk of highway robbery or the Carjacking, 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 im ...

Flap (aircraft)
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 outbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtiss SBC Helldiver
The Curtiss SBC Helldiver was a two-seat scout bomber and dive bomber built by the Curtiss-Wright Corporation. It was the last combat military biplane procured by the United States Navy. Delivered in 1937, it became obsolete even before World War II and was kept well away from combat with Axis fighters.Wheeler 1992, p. 27. Development There was controversy in the United States Navy's Bureau of Aeronautics (BuAer) in the early 1930s regarding two-seat fighter planes, monoplanes and the retractable undercarriage. In 1931, the Navy issued Design Specification No. 113, which detailed a requirement for a high-performance fighter with fixed undercarriage to be powered by the Wright R-1510Gunston p.199 or Pratt & Whitney's R-1535 radial engine. Seven companies submitted proposals and two companies, the Douglas Aircraft with their XFD-1 and the Chance Vought with their XF3U-1 were given contracts for one prototype each. Both of these aircraft were two-seat biplanes. The Navy the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vought SBU Corsair
The Vought SBU-1 Corsair was a two-seat, all-metal biplane dive bomber built by Vought Aircraft Company of Dallas, Texas for the US Navy. Its design was based upon the F3U-1 two-seat fighter that was abandoned when the Navy decided not to obtain any more two-seat fighters. Design and development The aircraft was equipped with a closed cockpit, had fixed landing gear, and was powered by a Pratt & Whitney R-1535 radial air-cooled engine as had the F3U-1, but also included a controllable pitch propeller and a new NACA cowl with adjustable cowling gills on the trailing edge of the cowl. The adjustable cowling gills permitted better control of cooling airflow over the engine. The SBU-1 completed flight tests in 1934 and went into production under a contract awarded in January 1935. The Corsair was the first aircraft of its type, a scout bomber, to fly faster than 200 mph. The last SBU Corsairs were retired from active service in 1941, being reassigned as trainers.Johnson 2008, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wright Cyclone Series
Wright Cyclone was the name given to a family of air-cooled radial piston engines designed by the Wright Aeronautical Corporation and used in numerous American aircraft in the 1930s, 1940s and 1950s. Background The Wright Aeronautical Corporation was formed in 1919, initially to develop liquid-cooled Hispano-Suiza V8 engines under license. In 1923 the Wright purchased the Lawrance Aero Engine Company, and with the purchase Charles Lawrance came to Wright as the Vice-President. Later that year the US Navy awarded Wright a contract to develop two new air-cooled radial engines. The first, called the P-1, was a 9-cylinder single row design of displacement that was derived from an earlier Lawrence design, it produced . The second, the P-2, had the same displacement as the P-1, but was an improved design that produced . Neither engine entered production, with the Navy selecting the superior Pratt & Whitney R-1340 Wasp, so in 1926 work started on the improved design, which became t ...
