For a space gun with a gun barrel of length (), and the needed velocity (), the acceleration is provided by the following formula: [citation needed] = For instance, with a space gun with a vertical "gun barrel" through both the Earth's crust and the troposphere, totalling ~60 km (37 miles) of length (), and a velocity enough to escape the Earth's gravity (escape velocity, which is 11.2 km/s or ...
Non-rocket spacelaunch refers to theoretical concepts for launch into space where much of the speed and altitude needed to achieve orbit is provided by a propulsion technique that is not subject to the limits of the rocket equation. [1] Although all space launches to date have been rockets, a number of alternatives to rockets have been proposed ...
Mass drivers can be used to propel spacecraft in three different ways: A large, ground-based mass driver could launch spacecraft away from Earth, the Moon, or another body. A small mass driver could act as a rocket engine on board a spacecraft, flinging pieces of material into space to propel itself.
A railgun or rail gun, sometimes referred to as a rail cannon, is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high-velocity projectiles. The projectile normally does not contain explosives, instead relying on the projectile's high kinetic energy to inflict damage. [ 2 ]
A rocket sled launch, also known as ground-based launch assist, catapult launch assist, and sky-ramp launch, is a proposed method for launching space vehicles. With this concept the launch vehicle is supported by an eastward pointing rail or maglev track that goes up the side of a mountain while an externally applied force is used to accelerate ...
Technologies related to a ram accelerator for direct space launch applications are: two-stage gas guns , multiple sidewall injection gas guns (JVL), railguns, and coilguns. Ram accelerators are currently used primarily for research into supersonic combustion. The scram cannon science fiction weapon was inspired by ram accelerators.
Headed by John Hunter, the SHARP gun fired projectiles using expanding hydrogen and achieved velocities of 3 km/s (6,700 mph) or Mach 8.8 for 5 kg (11 lb) projectiles. . Had the project continued, there were plans to elevate the tube and begin space launch trials potentially reaching speeds of up to 7 km/s (16,000 mph), or about Mach
The launch tube stretches into the distance to the east on the right (eventually curving up many kilometers away), next to the power plant which charges the SMES. RLVs return to land on the runway. StarTram is a proposed space launch system propelled by maglev technology. The initial Generation 1 facility is proposed to launch cargo only from a ...
