Propulsive Systems Overview:

• SCRAMJET

• Rocket and Ducted Rockets
• Turbomachinery

Craft Tech has been involved in the analysis of a broad variety of rocket propulsive flows and has dealt with complexities in multi-phase of this problem. Ducted rocket systems exhibit subsonic combustion and this presents a very different set of challenges than the supersonic combustion in scramjets. In the subsonic mode, the combustion process and the fluid mechanics is very sensitive to the turbulence characteristics and the separated zones in the flowfield which may induce unsteadiness in the flowfield.
