Path: ACPro/ACDesign
% Design an aircraft.
The function generates the group mass statement for the aircraft from
the range, speed and altitude of the aircraft along with the number of
passengers and the payload. The input is a data structure described
below.
The function fEngine is of the form
[thrust, sfc] = MyEngine( mach, p );
where p is the datastructure from StdAtm.
