PHYSICAL SCIENCES INC. — National Aeronautics and Space Administration SBIR Phase I: Z9.01

Description

Physical Sciences Inc. (PSI) proposes to design, develop and demonstrate an innovative high-performance, green, storable hybrid propellant system in a high mass fraction launch vehicle for small satellites. The hybrid system utilizes an innovative composite solid fuel technology that significantly enhances fuel regression rate and ignitibility relative to state-of-the-art hybrids, without relying on a multi-port fuel grain geometry, complex port flow behavior, or the use of metallic additives. The high energy, high density liquid oxidizer improves hybrid motor combustion capabilities and reduces logistical operational cost compared to current state-of-the-art cryogenic oxidizers. This new system offers all advantages associated with hybrid propulsion, including inherent safety and simplicity in design. In Phase I, the hybrid system efficacy will be quantified through subscale motor demonstrations. The results generated will be utilized to conduct a realistic system level design of the propulsion system for full-scale demonstration in Phase II.
