Mass driver

Science fiction has dealt with mass drivers as weapons, tools of industry, or indeed both, in numerous works such as The Moon Is a Harsh Mistress and Babylon 5. On the show Babylon 5 in the episode The Long, Twilight Struggle the Centauri use mass drivers to bomb the Narn homeworld, despite the fact that mass drivers had been outlawed by "every civilized planet". In later episodes, they elaborated that the mass drivers had been loaded with small asteroids from the Narn system. Not only did the mass drivers utterly devastate every major city on Narn, it drama ...

Catapults are siege engines using an arm to hurl a projectile a great distance. Any machine that hurls an object can be considered a catapult, but the term is generally understood to mean medieval siege weapons. The name is derived from the Greek κατα (against) and παλλειγ(to hurl (a missile)). Originally, "catapult" referred to a dart-thrower, while "ballista" referred to a stone-thrower, but over ...

Catapults can be classified according to the physical concept used to store and release the energy required to propel the projectile. The first catapult distinct from hand-held launchers (bows, crossbows, slings etc.) was the greek gastrophetes, a crossbow so large it was braced against the abdomen rather than being held in the hand, hence the nickname belly-bow. The next step from this was a larger form a crossbow mounted on a stand, including early versions of the oxybeles (Greek for bolt shooter) and the ballista (the Roman version ...

In Europe, the first catapults appeared in later Greek times (400 BC-300 BC), early adopters being Dionysius of Syracuse and Onomarchus of Phocis. Alexander the Great introduced the idea of using them to provide cover on the battlefield in addition to using them during sieges. Catapults were more fully developed in Roman and Medieval times, with the trebuchet being introduced a relatively short time before the advent of gunpowder, which made the catapult obsolete. Cannons replaced catapults as the standard siege w ...

By the start of Cosmic Era year 72, the Alliance's nuclear stockpile was destroyed, as was the ZAFT GENESIS superweapon. More importantly, the instigators of the war - Blue Cosmos leader Murata Azrael, ZAFT Supreme Council Chairman Patrick Zala, and rogue ZAFT commander Rau Le Creuset - were killed in action. Parties amendable to peace were now in control of the major factions. On March 10, CE 72, their representatives met at the ruins of Junius Sev ...

Heavy space fighters called "Mobile Armors" had been in use by the Atlantic Federation military since the early fifties CE (Cosmic Era), but they had many limitations in capabilities. Their small size meant they were tough targets to hit, but they were also difficult to armor adequately. A larger machine, PLANT strategists theorized, could do more than a Mobile Armor for relatively little more cost and would be able to carry more armor as well. To give these new mecha the best multi-environment combat capacity, a humanoid shape was chosen - ...

Another variation is to have a mass-driver on a spacecraft, and use it to "reflect" masses from a stationary mass-driver. Each deceleration and acceleration of the mass contributes to the momentum of the spacecraft. The spacecraft need not carry reaction mass, and doesn't even need much electricity, beyond the amount needed to replace losses in the electronics. The system could also be used to deliver pellets of fuel to the spacecraft for use in powering some other propulsion system. This cou ...

A spacecraft could carry a mass driver as its primary engine. With a suitable source of electrical power (probably a nuclear reactor) the spaceship could then use the mass driver to accelerate pieces of matter of almost any sort, boosting itself in the opposite direction. Since current linear motors can accelerate cargo to 30 km/s, an engine using one would have a specific impulse of about 30 km/s or 3,000 s. No theoretical limit is known for the size, acceleration or muzzle energy of linear motors. However, at higher muzzle velocitie ...

Generally speaking mass drivers are only practical for small objects at a few kilometers per second; for example 1kg at 2.5km/s. Larger objects usually go proportionally more slowly; and smaller objects may be projected at 20km/s or more. The limits are generally the cost of the silicon to switch the current and the cost of the power supply and temporary energy storage for it. Earth based Mass drivers for 1 tonne vehicles to orbit are ...
