StarTram is a proposed space launch system propelled by maglev technology. The initial Generation 1 facility is proposed to launch cargo only from a mountain peak at an altitude of 3 to 7 kilometres (9,800 to 23,000 ft) using an evacuated tube remaining at local surface level. Annual orbital lift was estimated at approximately 150,000 tons.
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 ...
A launch loop or Lofstrom loop is a design for a belt-based maglev orbital launch system that would be around 2000 km long and maintained at an altitude of up to 80 kilometres (50 mi). Vehicles weighing 5 metric tons would be electromagnetically accelerated on top of the cable which forms an acceleration track, from which they would be ...
The maglev system was co-developed by the South Korea Institute of Machinery and Materials (KIMM) and Hyundai Rotem. [51] [52] [53] It is 6.1 kilometres (3.8 mi) long, with six stations and a 110 kilometres per hour (68 mph) operating speed. [54] Two more stages are planned of 9.7 kilometres (6 mi) and 37.4 kilometres (23.2 mi).
Mass driver. A mass driver or electromagnetic catapult is a proposed method of non-rocket spacelaunch which would use a linear motor to accelerate and catapult payloads up to high speeds. Existing and proposed mass drivers use coils of wire energized by electricity to make electromagnets, though a rotary mass driver has also been proposed. [1]
The Electromagnetic Aircraft Launch System ( EMALS) is a type of electromagnetic catapult system developed by General Atomics for the United States Navy. The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston. EMALS was first installed on the lead ship of ...
An image of a proposed system of the Hyperloop system. In 2001, James R. Powell – a co-inventor of superconducting maglev in the 1960s – began leading an investigation into the prospect of using a maglev vactrain for space launch, dubbed StarTram. Theoretically, this would incur two orders of magnitude less cost than current rockets.
Launch loop (not to scale). The red marked line is the moving loop itself, blue lines are stationary cables. A launch loop, or Lofstrom loop, is a proposed system for launching objects into orbit using a moving cable-like system situated inside a sheath attached to the Earth at two ends and suspended above the atmosphere in the middle.
