Path: StraightLine/ConstantThrust
% Maximum straight-line distance achievable in specified time.
This is an analytic solution to compute the maximum distance achievable
for constant thrust, given the engine parameters. Its equivalent to just
getting the engine to that distance, without any additional payload.
The built-in demo shows the maximum distance for several values of exhaust
velocity over 10 years.
