TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
To-date, the realization of high-performance liquid bipropellant rocket engines in the micro-scale has largely been hindered by the inability to obtain "on-board" pressurization through a light-weight and low-complexity pump. Ventions seeks to fulfill this critical need by proposing the development of a low-risk pump that can be batch fabricated in a low-cost manner to provide significant performance improvements for a Mars Ascent Vehicle and other spacecraft.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed pump concept overcomes a key challenge of providing on-board pressurization for high-performance rocket engines, especially in the micro-scale. Hence, upon eventual integration with complete propulsion systems (thrust chamber, valves / tanks, etc.), it serves as critically-enabling technology for a new generation liquid bipropellant rocket engines in the 50-1000lbf thrust class, with T/W ratios of 150-200, and an Isp of ~330 sec. These engines may be batch-fabricated in a cost-effective manner and modularly stacked to cover a wide range of NASA applications, including Mars sample return missions, nanosat launch vehicles, lunar ascent / descent missions (precursor rovers, cargo, etc.), and Near-Earth-Object missions (sample return, drill reaction for sample implantation, etc.).

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Non-NASA applications for high-performance micro-rocket engines enabled by the proposed pump technology are likely to include commercial / military launch vehicles for low-cost and on-demand access to space for a variety of micro / small satellite payloads, upper stage propulsion for orbit insertion of commercial satellites, and apogee kick motors for orbit circularization of commercial satellites, etc. Additionally, the pump itself is expected to have non-aerospace applications in industrial pumping settings, and as a replacement for other high-pressure liquid pumps.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
