Title: Electromagnetic coilgun launcher for space applications

Electromagnetic coilgun launcher for space applications A ground-based electrically-powered launcher could significantly reduce the complexity and cost of space launches for moderate-weight payloads. The electromagnetic launch complex could greatly reduce the amount of fuels handling, reduce the turn-around time between launches, allow more concurrence in launch preparation, reduce the manpower requirements for launch vehicle preparation and increase the reliability of launch by using more standardized vehicle preparations. The launch requires high acceleration, so the satellite package must be hardened. This paper presents results of a study to estimate the required launcher parameters, and estimate the cost of such a launch facility. This study is based on electromagnetic gun technology which is constrained to a coaxial geometry to take advantage of the efficiency of closely-coupled coils. The launcher energy and power requirements fall in the range of 40{endash}260 GJ and 20{endash}400 GW electric. Parametric evaluations have been conducted with a launcher length of 1{endash}2 km, exit velocity of 1{endash}6 km/s, and payloads to low earth orbit of 100{endash}1000 kg. {copyright} {ital 1996 American Institute of Physics.}
