Rockets in Planebuilder?

What is the best way to sim a rocket in Planebuilder?

Would a bypass ratio of 1 (a turbojet) be the best option?

What about the effiency tab? Should it be lower than 20% to simulate higher fuel consumption or 30% to give the most power to weight ratio?

Also could a ramjet be simmed the same way as a rocket?

Many thanks in advance.

I'm working on doing both for add-ons to Planebuilder but it is rather problematic.

Jet velocities;

Subsonic turbofan <500m/s
Supersonic Turbojet <1000m/s
Solid Fuelled Rocket 1000 - 2500m/s
Liquid Fuelled Rocket 2000 - 3500m/s

Not quite sure on the fuel consumption for the rockets but this'll allow some quick and dirty calcs.
