30 -- FLYWHEEL PRIME MOVER TECHNOLOGY SOL N68335-96-RFI-613 DUE 053096 POC Ms. Barbara Petrzilka Code 213BP, (908) 323-2067. This is a Request for Information only. There is no solicitation package available. Request for Information regarding flywheel based power systems technology applicable as prime movers for powered and self propelled aviation support equipment. The US Navy and Marine Corps operate many thousands of powered and self propelled equipment items used in support of aircraft operations, both landbased and shipboard. Most all of these items are currently powered by diesel powerplants. The Naval Air Warfare Center Aircraft Division is currently undertaking a major study to determine whether diesel power systems or some alternative power system (or some combination thereof) is the best power system option for future Navy powered and self propelled aviation support equipment. It may also be cost/mission effective to retrofit diesel engines out of existing aviation support equipment and replace them with an alternative powerplant, such as a flywheel based prime mover. Information is requested regarding existing flywheel based systems, flywheel based systems currently in development, and future projections for flywheel based systems design and performance. Current power requirements range from appx. 30KW to appx. 400KW. Information forwarded may include, but should not be limited to: FLYWHEEL BASED POWER SYSTEMS: Principle of operation, system design; flywheel energy source (e.g. hybrid diesel-flywheel system, external equipment, etc.); flywheel system efficiency; flywheel system cost (including operating costs); flywheel system reliability (MTBF); maintenance requirements; environmental effects (eg. ambient temperature, humidity, shock, vibration, electromagnetic interference (EMI) susceptility and emissions, ability to operate laid over or inverted, etc.); hazardous materials; research papers or demonstration project reports; field use data; any other related pertinent information. The above areas are not exclusive and any information or any other method is welcome. It is requested that information be submitted no later than 30 May 1996 to Ms. Barbara Petrzilka Code 213000B129-2, Highway 547, Lakehurst, NJ 08733-5082, who may be reached at (908) 323-2067.
