Path: ACPro/ACEngine
% Model of a combined cycle engine with turbofan, ramjet and rocket.
This type of engine could be used in the first stage of a two stage
to orbit booster or in a single stage to orbit booster.
The mode field is
0 Turbofan/turbojet
1 Ramjet
2 Rocket
You can pick the turbojet model, both Turbofan and Turbojet are
compatible, but Ramjet is fixed to be Ramjet.m.
The rocket engine model is the simple RocketFromUEAndT.m
that computes exhaust velocity and specific impulse from the
values at two pressures.
Type TurboRamRocket for a demo of an all H2 engine.
