Abstract:
A method of launching from the lunar surface is analyzed, in which the payload launched is swung on a high-strength cable until it reaches the desired launch speed. For a moderate acceleration limit of 11.5 g, a cable length of 50 km would be sufficient to launch into a lunar escape trajectory. If lower accelerations are desired, the cable length must be proportionately longer. Analysis shows that the concept will be feasible with existing materials, and will be simple to implement using advanced materials.
