KEYWORDS: space-based radar, spacecraft, space power supply, space battery, satellite power system, satellite, Lithium-ion batteries AF06-174 TITLE: Power and Aeropropulsion TECHNOLOGY AREAS: Air Platform The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), which controls the export and import of defense-related material and services. Offerors must disclose any proposed use of foreign nationals, their country of origin, and what tasks each would accomplish in the statement of work in accordance with section 3.5.b.(7) of the solicitation. OBJECTIVE: Develop innovative technologies that provide improvements in AF - 164
small air vehicle propulsion devices, electrical power systems, thermal management techniques and power generation. DESCRIPTION: The Propulsion Directorate pursues and solicits innovative ideas offering performance advances in engines along with their subsystems. Of special interest are small (less than 200-pound thrust/horsepower) engines with improved affordability, performance, reliability, endurance, and fuel consumption characteristics. We need to understand the propulsion system design trade space. Propulsion options and their subsystems for assessment include internal combustion and gas turbine engines, fuel cells, electric motors, and energy storage. Successful proposals shall deal with developing innovative solutions to improving the performance in small UAVs and their subsystems leading to design, fabrication, and full-scale ground demonstration of one or more engine configurations. Performance goals are increased propulsion effectiveness, reliability and affordability. Specifically, a 70% increase in thrust/airflow, a 30% decrease in specific fuel consumption, a 45% reduction in cost, and a 50% increase in energy density storage over state-of-the-art. Payoffs expected are a 20% increase in range, a 30% increase in payload and a 100% increase in loiter times. Offerors are strongly encouraged to establish relationships with suppliers of the aerospace systems relevant to their research in order to facilitate technology transition. Proposed efforts shall emphasize dual-use technologies that clearly offer commercial as well as military applications. Proposals emphasizing commercial off the shelf technologies adaptation to military applications are also encouraged.
