Abstract: To transport payload into lunar transfer orbit using spinning tether system, reusable payload transport design were proposed and analysed. When final design was decided, open-loop reference control of payload transport stage was developed using optimal control theories. For the insufficient thrust case in LEO orbit, Hamiltonian on/off control was used to solve the problem. Numerical results indicate that the final transport design is able to transport payload into desired orbit, and the control law could satisfy mission requirement. Compared to conventional rocket transport, much less propellant is required by the spinning system with system reusability.
