The three rotor sling, a momentum transfer device, is described. The dynamics of multi-rotor systems are explained, and the three rotor system is shown to be favored over one and two rotor systems because a system of three rigid rotors is able to maintain both constant angular momentum and constant kinetic energy with no expenditure of propellant. A point design is presented for a lunar surface-to-orbit transport system based on a three rotor sling. The transport system is shown to improve on previous concepts by reducing the cost of returning cargo containers to the lunar surface.
