Path: Propulsion/Electric
% Finds an electric thrust propelled mass-optimal vehicle.
The routine takes the power-to-mass ratio and finds the constant exhaust
velocity that minimizes the total mass. Since v11 uses fminbnd to prevent
singularities due to the structural ratio.
Type OptimalVehicle for a demo.
