A Low Cost Automated Radiosonde Launch System

Not Available ORBITEC proposes to assess an innovative multi-mode propulsion system based on a unique new vortex combustion technology. The basic operational modes include vortex hybrid rocket, cool-wall ramjet/scramjet, and cool-wall liquid propellant rocket. The Vortex-Combustion Combined Cycle (VCCC) engine has several important advantages: high volumetric loading, simple combustion chamber construction, stable, efficient combustion, reduced thermal failure modes, low-weight, low-cost, and full trajectory operational capability in a single engine. Phase I will involve selecting various propulsion system cycles, analyzing key subsystems, determining overall system performance and physical characteristics, comparing the VCCC cycles to competitive rocket and airbreathing cycles, and identifying key demonstration technologies. In Phase II experiments will be conducted to demonstrate the key technologies identified in Phase I. Additional analysis will also be performed, and vehicle designs will be produced.
