Path: Propulsion/Electric
% Design an electric propulsion system.
Uses the payload mass, the required delta-V, the required thrust, the ratio of
structure to fuel mass (for tanks, etc.) and the power per unit mass. It will
check to see the the input exhaust velocity is less than the minimum based on
the structural ratio.
Type ElectricPropulsionDesign for a demo.
