Path: StraightLine/ConstantAccel
% Fuel mass for a constant accel/power electric propulsion system
Assumes constant power and constant acceleration. The spacecraft slows to zero
velocity at its target. This uses a straight line model. This model assumes
power is constant. This means exhaust velocity increases as the mass drops.
There are two cases in the demo, one for a flyby mission and one for a
rendezvous.
