Regeneratively-Cooled, Turbopump-Fed, Small-Scale Cryogenic Rocket Engines

To-date, the realization of small-scale, high-performance liquid bipropellant rocket engines has largely been limited by the inability to operate at high chamber pressures in a regeneratively-cooled environment using on-board pumps for propellant pressurization. Ventions seeks to fulfill this critical need by using a novel fabrication scheme to realize small-scale thrust chambers and turbopumps, and proposes to extend its previously-demonstrated technologies (under DARPA and NASA sponsored efforts) to develop a 3,000lbf, regeneratively-cooled, cryogenic propulsion system with a T/W ratio of approx. 100 and a vacuum Isp up to 355sec.
