Joysticks
A joystick, sometimes called a flight stick, is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. A joystick, also known as the control column, is the principal control device in the cockpit of many civilian and military aircraft, either as a centre stick or side-stick. It often has supplementary switches to control various aspects of the aircraft's flight. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick. Joysticks are also used for controlling machines such as cranes, trucks, underwater unmanned vehicles, wheelchairs, surveillance cameras, and zero turning radius lawn mowers. Miniature finger-operated joysticks have been adopted as input devices for smaller electronic equipment such as mobile phones. Aviation Joystic ...

Analog Stick
An analog stick (or analogue stick in British English), sometimes called a control stick or thumbstick, is an input device for a controller (often a game controller) that is used for two-dimensional input. An analog stick is a variation of a joystick, consisting of a protrusion from the controller; input is based on the position of this protrusion in relation to the default "center" position. While digital sticks rely on single electrical connections for movement (using internal digital electrical contacts for up, down, left and right), analog sticks use continuous electrical activity running through potentiometers to measure the exact position of the stick within its full range of motion. The analog stick has greatly overtaken the D-pad in both prominence and usage in console video games. Usage in video games The initial prevalence of analog sticks was as peripherals for flight simulator games, to better reflect the subtleties of control required for such titles. It was during ...

Missile
In military terminology, a missile is a missile guidance, guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles are thus also called guided missiles or guided rockets (when a previously unguided rocket is made guided). Missiles have five system components: targeting (warfare), targeting, guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface missile, surface-to-surface and air-to-surface missiles (ballistic missile, ballistic, cruise missile, cruise, anti-ship missile, anti-ship, anti-submarine missile, anti-submarine, anti-tank missile, anti-tank, etc.), surface-to-air missiles (and anti-ballistic missile, anti-ballistic), air-to-air missiles, and anti-satellite weapons. Airborne explosive devices without propulsion are referred to as shell (projectile), shells if fired by an artillery piece and bombs if dropped by an aircraft. Unguided jet- or rocke ...

V-2 Rocket
The V-2 (german: Vergeltungswaffe 2, lit=Retaliation Weapon 2), with the technical name '' Aggregat 4'' (A-4), was the world’s first long-range guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a "vengeance weapon" and assigned to attack Allied cities as retaliation for the Allied bombings of German cities. The rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944. Research into military use of long-range rockets began when the graduate studies of Wernher von Braun attracted the attention of the Wehrmacht. A series of prototypes culminated in the A-4, which went to war as the . Beginning in September 1944, over 3,000 were launched by the Wehrmacht against Allied targets, first London and later Antwerp and Liège. According to a 2011 BBC documentary, the attack ...

Wasserfall Missile
The ''Wasserfall Ferngelenkte FlaRakete'' (Waterfall Remote-Controlled A-A Rocket) was a German guided supersonic surface-to-air missile A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of anti-aircraft syst ... project of World War II. Development was not completed before the end of the war and it was not used operationally. The system was based on many of the technologies developed for the V-2 rocket program, including the rocket itself, which was essentially a much scaled-down version of the V-2 airframe. The rocket motor used new fuels as it was expected to be stored in ready-to-fire form for months, and the guidance system used external fins for control instead of relying entirely on the steerable rocket motor exhaust. Among the many development problems, control of the high-speed rocket was a sign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azon
AZON (or Azon), from " azimuth only", was one of the world's first guided weapons, deployed by the Allies and contemporary with the German Fritz X. Officially designated VB-1 ("Vertical Bomb 1"), it was invented by Major Henry J. Rand and Thomas J. O'Donnell during the latter stages of World War II as the answer to the difficult problem of destroying the narrow wooden bridges that supported much of the Burma Railway. AZON was essentially a general-purpose AN-M65 bomb with a quadrilateral 4-fin style radio controlled tail fin design as part of a "tail package" to give the desired guidance capability, allowing adjustment of the vertical trajectory in the yaw axis, giving the Azon unit a lateral steering capability (meaning it could only steer left and right, and could not alter its pitch or rate of fall). This lack of any pitch control meant that the bombardier still had to accurately release it with a bombsight to ensure it could not fall short of or beyond the target. The "t ...

Fritz-X
Fritz X was the most common name for a German guided anti-ship glide bomb used during World War II. ''Fritz X'' was the world's first precision guided weapon deployed in combat and the first to sink a ship in combat. ''Fritz X'' was a nickname used both by Allied and ''Luftwaffe'' personnel. Alternative names include Ruhrstahl SD 1400 X, Kramer X-1, PC 1400X or FX 1400 (the latter, along with the unguided PC 1400 ''Fritz'' nickname, is the origin for the name "Fritz X"). History ''Fritz X'' was a further development of the PC 1400 (''Panzersprengbombe, Cylindrisch'' 1,400 kg) German Wikipedia's WW II PC-series bomb specifications, German for "armor-piercing bomb, cylindrical". armour-piercing high-explosive bomb, itself bearing the nickname ''Fritz''. It was a penetration weapon intended to be used against armored targets such as heavy cruisers and battleships. It was given a more aerodynamic nose, four stub wings, and a box-shaped tail unit consisting of a roughly 12-sid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henschel Hs 293
The Henschel Hs 293 was a World War II German radio-guided glide bomb. It is the first operational anti-shipping missile, first used unsuccessfully on 25 August 1943 and then with increasing success over the next year, ultimately damaging or sinking at least 25 ships. Allied efforts to jam the radio control link were increasingly successful despite German efforts to counter them. The weapon remained in use through 1944 when it was also used as an air-to-ground weapon to attack bridges to prevent the Allied breakout after D-Day, but proved almost useless in this role. Development The Hs 293 project was started in 1940, based on the "Gustav Schwartz Propellerwerke" pure glide bomb that was designed in 1939. The Schwartz design did not have a terminal guidance system; instead, it used an autopilot to maintain a straight course. It was intended to be launched from a bomber at sufficient distance to keep the aircraft out of range of anti-aircraft fire. A Henschel team, und ...
