Hard Launch
Hard launching is a launch system of a guided missile, where the missile's rocket engine is ignited while still inside the launch assembly or tube. This is technically simpler than soft launching but produces a large backblast area. See also *Soft launch (missile) Soft launching is the method of launching a missile (such as an anti-tank guided missile) in such a way that the rocket motor ignites outside of the launch tube; the missile is ejected non-explosively. The objective is to minimize the risk of dama ... * Hot launch and cold launch Missile launchers Missile operation Guided missiles {{missile-stub ...

Guided Missile
In military terminology, a missile is a 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, guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles (ballistic, cruise, anti-ship, anti-submarine, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Unguided jet- or rocket-propelled weapons are usually described as rocket artillery. Historically, the word ''missile'' referred to any projectile that is thrown, shot or propelled towards a target; this usage is ...

Rocket Engine
A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal exhaust is hydrogen, the lightest of all elements, but chemical rockets produce a mix of heavier species, reducing the e ...

Soft Launch (missile)
Soft launching is the method of launching a missile (such as an anti-tank guided missile) in such a way that the rocket motor ignites outside of the launch tube; the missile is ejected non-explosively. The objective is to minimize the risk of damage to the launcher by maintaining a safe distance. This is in contrast with hard launching, where the missile's rocket engine is ignited while still inside the launch assembly or tube, which generates a backblast area. A similar concept called cold launch was pioneered by the Soviet Union for application in vertical launch system clusters on board ships.

Backblast Area
The backblast area is a cone-shaped area behind a rocket launcher, rocket-assisted takeoff unit or recoilless rifle, where hot gases are expelled when the rocket or rifle is discharged. The backblast area is dangerous to ground personnel, who may be burned by the gases or exposed to overpressure caused by the explosion. In confined spaces, common in urban warfare, even the operators themselves may be at risk due to deflection of backblast by walls or sturdier civilian vehicles behind them. Soft launch methods diminish backblast by ejecting the projectile some distance before its main rocket motor ignites. Backblast can also be reduced by adding a countermass that is expelled out the rear of the weapon. For example, the AT4-CS (confined space variant) uses saltwater, along with a lower-velocity projectile.

Vertical Launching System
A vertical launching system (VLS) is an advanced system for holding and firing missiles on mobile naval platforms, such as surface ships and submarines. Each vertical launch system consists of a number of ''cells'', which can hold one or more missiles ready for firing. Typically, each cell can hold a number of different types of missiles, allowing the ship flexibility to load the best set for any given mission. Further, when new missiles are developed, they are typically fitted to the existing vertical launch systems of that nation, allowing existing ships to use new types of missiles without expensive rework. When the command is given, the missile flies straight up far enough to clear the cell and the ship, then turns on to the desired course. A VLS allows surface combatants to have a greater number of weapons ready for firing at any given time compared to older launching systems such as the Mark 13 single-arm and Mark 26 twin-arm launchers, which were fed from behind by a ...

Missile Launchers
A rocket launcher is a weapon that launches an unguided, rocket-propelled projectile. History The earliest rocket launchers documented in imperial China consisted of arrows modified by the attachment of a rocket motor to the shaft a few inches behind the arrowhead. The rocket was propelled by the burning of the black powder in the motor; these should not be confused with early fire arrows, which were conventional arrows carrying small tubes of black powder as an incendiary that ignited only after the arrow hit its target. The rocket launchers were constructed of wood, basketry, and bamboo tubes. The launchers divided the rockets with frames meant to keep them separated, and the launchers were capable of firing multiple rockets at once. Textual evidence and illustrations of various early rocket launchers are found in the 1510 edition of the ''Wujing Zongyao'' translated by Needham and others at Princeton University. (The original ''Wujing Zongyao'' was compiled between 1040 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
