Novel Propellant, High-Energy Upper Stages for Space Access

As low-cost space access drives the design of new 3,000 lb-to-orbit launch systems, inexpensive, high-energy stages with velocity increments of over 20,000 feet/sec are required. Whittinghill Aerospace proposes development of a highly energetic stage design for DARPAs XS-1 launch vehicle that makes use of novel propellants and a high mass fraction structure. A multi-disciplinary optimization design approach of physical and operational parameters for the upper stage will be employed in concert with propellant synthesis and development. Whittinghill Aerospace will leverage existing assets and facilities to fire the best propellant candidate in an 800 lb thrust, proof-of-concept test motor to validate c* performance predictions.
