XF2R Dark Shark
The Ryan XF2R Dark Shark was an American experimental aircraft built for the United States Navy that combined turboprop and turbojet propulsion. It was based on Ryan Aeronautical's earlier FR Fireball, but replaced the Fireball's piston engine with a turboprop engine. Design and development The XF2R Dark Shark was based on Ryan Aeronautical's earlier FR Fireball, but replaced the Fireball's piston engine with a General Electric T31 turboprop engine driving a 4-bladed Hamilton Standard propeller. The turboprop made for much improved performance over the Fireball, and Ryan proposed the XF2R-2 to use a Westinghouse J34 turbojet in place of the General Electric J31 used as the auxiliary turbojet for the XF2R-1. The XF2R-2 also had a squared-off vertical stabilizer and jet intakes moved to the sides of the forward fuselage with NACA duct A NACA duct, also sometimes called a NACA scoop or NACA inlet, is a common form of low- drag air inlet design, originally developed by the U.S. ...

Ryan Aeronautical
The Ryan Aeronautical Company was founded by T. Claude Ryan in San Diego, California, in 1934. It became part of Teledyne in 1969, and of Northrop Grumman when the latter company purchased Ryan in 1999. Ryan built several historically and technically significant aircraft, including four innovative V/STOL designs, but its most successful production aircraft was the Ryan Firebee line of unmanned drones used as target drones and unmanned air vehicles. History Early history In 1922, T.C. Ryan founded a flying service in San Diego that would lead to several aviation ventures bearing the Ryan name, including Ryan Airline Company founded in 1925. T.C. Ryan, whose previous companies were best known for building Charles Lindbergh's transatlantic '' Spirit of St. Louis'', actually had no part in building the famous aircraft. Ryan had been owner or partner in several previous companies, one of which also bore the name Ryan Aeronautical. The '' Spirit of St. Louis'' was not built b ...

M2 Browning
The M2 machine gun or Browning .50-caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed near the end of World War I by John Browning. While similar to Browning's M1919 Browning machine gun, which was chambered for the .30-06 Springfield, .30-06 cartridge, the M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It has been used against infantry, light armored vehicles, watercraft, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan (2001–present), War in Afghanistan. It is the primary heavy mac ...

Aircraft With Retractable Tricycle Landing Gear
An aircraft ( aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ...

Turboprop Aircraft
A turboprop is a gas turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the fuel-air mixture then combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough power to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turbine ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple wings. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

1940s United States Fighter Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Decimus Clodius Septimius Albinus Caesar became a Roman Consul. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Grumman XTB3F Guardian
The Grumman AF Guardian is the first purpose-built anti-submarine warfare (ASW) carrier-based aircraft to enter service with the United States Navy.Kowalski 1991, p. 3. It consisted of two airframe variants, one for detection gear, the other for weapons. The Guardian remained in service until August 1955, when it was replaced by the twin-engined Grumman S-2 Tracker. The Guardian was the largest single-engine piston-powered carrier aircraft ever to see service. Design and development The original design concept for the aircraft that would become the Guardian, the Grumman TB2F, XTB2F of 1944, was for a twin-engined aircraft with a warload and a range of .Kowalski 1991, pp. 2–3. This was considered to be too large for practical use from an , and was cancelled in 1945, replaced by a modified Grumman F7F Tigercat, the Grumman XTSF, XTSF-1. However, this too was considered impractical, and another alternative, the internally developed Grumman Model G-70, was selected instead, be ...
