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 ...
On Earth, a mass-driver design could possibly use well-tested maglev components. To launch a space vehicle with humans on board, a mass driver's track would need to be almost 1000 kilometres long if providing almost all the velocity to Low Earth Orbit, though a lesser length could provide major
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).
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.
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, providing greater precision and faster recharge ...
Maglev, or magnetic levitation, is a system of transportation that suspends, guides and propels vehicles, predominantly trains, using magnetic levitation from a very large number of magnets for lift and propulsion. This method has the potential to be faster, quieter and smoother than wheeled mass transit systems.
