Target-tug
A target tug is an aircraft which tows an unmanned drone, a fabric drogue or other kind of target, for the purposes of gun or missile target practice. Target tugs are often conversions of transport and utility aircraft, as well as obsolescent combat types. Some, such as the Miles Martinet, were specially designed for the role. It was, and is, a relatively hazardous job, as live fire is typically employed and the people doing the shooting are usually still in training. History World War 2 Prior to and during World War II target tugs were typically operated by the air arms on behalf of which they flew, and were usually conversions of aircraft that had failed in combat or that were otherwise unsuitable or obsolete in their design roles (see Fairey Battle and Short Sturgeon). These aircraft typically trailed a drogue fabric sleeve at the end of a several-thousand metre long cable. Student fighter pilots or air gunners would shoot at the target from other aircraft using painted bull ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawker Henley
The Hawker Henley was a British two-seat target tug derived from the Hawker Hurricane that was operated by the Royal Air Force during the Second World War. Design and development In 1934 Air Ministry Specification P.4/34 was issued which called for a light bomber that could also be deployed in a close-support role as a dive-bomber. Fairey, Gloster and Hawker attempted to fulfil this need and competition was tight to attain the highest performance possible. As the aircraft required only a modest bomb load and with performance being paramount, the Hawker design team chose to focus its efforts on developing an aircraft similar in size to their Hurricane fighter. The Hurricane was then in an advanced design stage and there would be economies of scale if some assemblies were common to both aircraft. This resulted in the Henley, as it was to become known, sharing identical outer wing panel and tailplane jigs with the Hurricane. Both were equipped with the Rolls-Royce Merlin engi ...

Douglas Skyraider
The Douglas A-1 Skyraider (formerly known as the AD Skyraider) is an American single-seat attack aircraft in service from 1946 to the early 1980s. The Skyraider had an unusually long career, remaining in front-line service well into the Jet Age (when most piston-engine attack or fighter aircraft were replaced by Jet aircraft); thus becoming known by some as an "anachronism". The aircraft was nicknamed "Spad", after the French World War I fighter. It was operated by the United States Navy (USN), the United States Marine Corps (USMC), and the United States Air Force (USAF), and also saw service with the British Royal Navy, the French Air Force, the Republic of Vietnam Air Force (RVNAF), and others. It remained in U.S. service until the early 1970s. The jet powered A-10 Thunderbolt II was based on specifications for a modernized Skyraider with a heavy payload and good endurance. Design and development The piston-engined, propeller-driven Skyraider was designed during World War I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairey Firefly
The Fairey Firefly is a Second World War-era carrier-borne fighter aircraft and anti-submarine aircraft that was principally operated by the Fleet Air Arm (FAA). It was developed and built by the British aircraft manufacturer Fairey Aviation Company. Development of the Firefly can be traced back to pair of specifications issued by the British Air Ministry in 1938, calling for new naval fighter designs. Designed to the contemporary FAA concept of a two-seat fleet reconnaissance/fighter, the pilot and observer were positioned at separate stations. In flight, the Firefly was superior in terms of both performance and firepower to its predecessor, the Fairey Fulmar. Due to a protracted development, the type only entered operational service towards the end of the conflict, at which point it was no longer competitive as a fighter. The limitations of a single engine in a relatively heavy airframe reduced its performance, but the Firefly proved to be a fairly sturdy, long-ranged, and ...

Hawker Sea Fury
The Hawker Sea Fury is a British fighter aircraft designed and manufactured by Hawker Aircraft. It was the last propeller-driven fighter to serve with the Royal Navy, and one of the fastest production single reciprocating engine aircraft ever built. Developed during the Second World War, the Sea Fury entered service two years after the war ended. It proved to be a popular aircraft with a number of overseas militaries and was used during the Korean War in the early 1950s, and by the Cuban air force during the 1961 Bay of Pigs Invasion. The Sea Fury's development was formally initiated in 1943 in response to a wartime requirement of the Royal Air Force (RAF), with the aircraft initially named Fury. As the Second World War drew to a close, the RAF cancelled their order for the aircraft; however, the Royal Navy saw the type as a suitable carrier aircraft to replace a range of increasingly obsolete or poorly suited aircraft being operated by the Fleet Air Arm.

West Germany
West Germany is the colloquial term used to indicate the Federal Republic of Germany (FRG; german: Bundesrepublik Deutschland , BRD) between its formation on 23 May 1949 and the German reunification through the accession of East Germany on 3 October 1990. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from eleven states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France. The FRG's provisional capital was the city of Bonn, and the Cold War era country is retrospectively designated as the Bonn Republic. At the onset of the Cold War, Europe was divided between the Western and Eastern blocs. Germany was divided into the two countries. Initially, West Germany claimed an exclusive mandate for all of Germany, representing itself as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stall Speed
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number. Stalls in fixed-wing flight are often experienced as a sudden reduction in lift as the pilot increases the wing's angle of attack and exceeds its critical angle of attack (which may be due to slowing down below stall speed in level flight). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller thru ...

Aerial Refueling Tanker
Aerial refueling, also referred to as air refueling, in-flight refueling (IFR), air-to-air refueling (AAR), and tanking, is the process of transferring aviation fuel from one aircraft (the List of tanker aircraft, tanker) to another (the receiver) while both aircraft are in flight. The two main refueling systems are ''#Probe-and-drogue, probe-and-drogue'', which is simpler to adapt to existing aircraft, and the ''#Flying boom, flying boom'', which offers faster fuel transfer, but requires a dedicated Boom operator (military), boom operator station. The procedure allows the receiving aircraft to remain airborne longer, extending its range or Loiter (aeronautics), loiter time. A series of air refuelings can give range limited only by crew fatigue/physical needs and engineering factors such as engine oil consumption. As the receiver aircraft can be topped up with extra fuel in the air, air refueling can allow a takeoff with a greater Payload (air and space craft), payload which coul ...

Clutch
A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears. In a torque-controlled drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the ...

Ram Air Turbine
A ram air turbine (RAT) is a small wind turbine that is connected to a hydraulic pump, or electrical generator, installed in an aircraft and used as a power source. The RAT generates power from the airstream by ram pressure due to the speed of the aircraft. Operation Modern aircraft generally use RATs only in an emergency. In case of the loss of both primary and auxiliary power sources the RAT will power vital systems (flight controls, linked hydraulics and also flight-critical instrumentation). Some RATs produce only hydraulic power, which is in turn used to power electrical generators. In some early aircraft (including airships), small RATs were permanently mounted and operated a small electrical generator or fuel pump. Some constant-speed propellers, such as those of the Argus As 410 engines used in the Focke-Wulf Fw 189, used a propeller turbine on the spinner to power a self-contained pitch governor controlling this constant speed. Modern aircraft generate power in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
