Latest Patents
Altman's latest patents include a groundbreaking invention related to high regression rate hybrid rocket propellants. This invention comprises a new process for developing high regression rate propellants for application to hybrid rockets and solid fuel ramjets. The process involves the use of a criterion to identify propellants that form an unstable liquid layer on the melting surface of the propellant. Entrainment of droplets from the unstable liquid-gas interface can substantially increase propellant mass transfer, leading to much higher surface regression rates than those achievable with conventional hybrid propellants. The main reason for this improvement is that entrainment is not limited by heat transfer to the propellant from the combustion zone. This innovative process has been used to identify a new class of non-cryogenic hybrid fuels whose regression rate characteristics can be tailored for specific missions. The fuel can serve as the basis for a simpler hybrid rocket design, resulting in reduced cost, reduced complexity, and increased performance.
