Path: StraightLine/ConstantThrust
% Report of constant-thrust engine properties
If there are no outputs the report is printed to the command line. If the
thrust is empty, the payload-independent quantities will be reported -
payload mass fraction, payload specific power, delta-V. If the thrust is
zero, the value will be computed from the payload mass.

Form:
EngineReport( [], d ) % report
EngineReport( 0, d ) % compute thrust for mP
