Hybrid Propulsion Systems for Undersea Weapons Navy STTR FY2005 Sol No.: Navy STTR FY2005 Topic No.: N05-T024 Topic Title: Hybrid Propulsion Systems for Undersea Weapons Proposal No.: N054-024-0085 Firm: Barber-Nichols Inc. 6325 West 55th Avenue Arvada, Colorado 80002 Contact: Dave Lowe Phone: (303) 421-8111 Web Site: www.barber-nichols.com Abstract: Leveraging existing Simulation Based Design and Multidisciplinary Optimization (SBD / MDO) analyses, optimal hybrid torpedo configuration(s) will be developed. Engineering analyses will be performed on a new chemical oxygen storage and delivery concept and turbomachinery for the hybrid propulsion system. Analysis performed will result in component performance metrics that will be used in system optimization programs. The collaboration between organizations is facilitated through an ESB (Engineering Services Broker), that will provide access to computer programs, spreadsheets, and other applications that both reside and run on host computer(s) at the research institution and small business involved. The framework provides functionalities for integrating multiple applications, including those requiring human mediation. The selected optimized concept will be tested in a brassboard configuration in Phase II. Benefits: The technology developed in Phase II will have the best use in systems where controlled oxygen generation from a high-density apparatus is desired. The technology will be especially useful in applications in which air separation for the production of oxygen is not an option. These applications would include all applications underwater and in space. Other oxygen production/storage technologies that could be used for these applications include oxygen candles, compressed oxygen bottles and liquid oxygen. The overall oxygen density of the lithium perchlorate decomposition system has the potential to exceed that of any of these current technologies. Additionally, the system developed in phase II will have the ability to produce controlled rates of oxygen that may even be stopped and restarted. One of the most promising markets for use of this technology is in underwater applications. The controlled generation rate will make it ideal for the fuel cell power source in which this solicitation concerns. Fuel cells will become more prevalent as the predominant power source in underwater applications in the future and this technology could prove to be the most efficient source of oxygen to supply to these fuel cells. BN intends to research this and other similar markets that will aid in design of a modular product line of reusable oxygen generation systems for use in military and civilian applications. Several of the technologies to be demonstrated in this Phase I STTR program (and follow-on work) have a number of potential non-DoD applications. For example, technologies demonstrated for hybrid torpedo applications may be used in commercial UUVs and mine rescue vehicles (which often must operate in oxygen depleted environments). The proposers will continue to seek government and industry partners that can help facilitate commercialization of the technologies to be demonstrated in this program. Return
