Electromagnetic launch by linear quadrupole field
Orlando, FL(2008)
Abstract
This paper presents a novel electromagnetic launch concept based on a DC linear quadrupole field with no axial component. The proposed design enables contact-free power transfer to the launch vehicle while removing the need of switching power or AC induction. Passive damping windings are proposed to provide radial stability during launch. The 6-DOF dynamics of the launch vehicle, including the coupling of electromagnetic propulsion and damping, has been simulated. The result shows that the proposed method provides sufficient thrust for the proposed mission while providing satisfactory radial stability during launch.
