Abstract:
For supersonic and hypersonic flight conditions with ramjets, trajectory calculations have necessarily to be coupled with the engine performances. In space transportation systems ramjets will be employed in a relatively wide range of Mach-numbers. and therefore not always near the optimum design point. Optimization of several physical parameters along the trajectory will be inevitable. This paper discusses some of these parameters and their importance for an ascent trajectory, having a minimum fuel requirement.
