Hybrid Self-Control and Power-Harvesting Tile Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-093 Topic Title: Hybrid Self-Control and Power-Harvesting Tile Proposal No.: N101-093-1159 Firm: Physical Optics Corporation Information Technologies Division 20600 Gramercy Place, Bldg. 100 Torrance, California 90501-1821 Contact: Nathanael Kim Phone: (310) 320-3088 Web Site: www.poc.com Abstract: To address these Navy needs for utilizing thermal and vibration effects in an aircraft carrier deck environment, Physical Optics Corporation (POC) proposes to develop a new HYbrid Self-controlling and POwer-harvesting Tile (HYSPOT) for the flight deck. The proposed HYSPOT is based on self-sensed/self-control vibration suppression for vibration-damping and power-harvesting structures to convert thermal energy of jet exhaust to electrical energy. The HYSPOT has a reinforced, tile-like modular structure that can be laid out (or interconnected) to cover a wide area without electric wiring. The innovative self-sensed/self-control design for vibration suppression and high-efficiency power harvesting enables the HYSPOT to damp/absorb impinging jet energy and to convert it to useful energy, as well as to reduce acoustic noise. In Phase I, POC will demonstrate the feasibility of the HYSPOT concept with numerical models and experiments on system components showing power-harvesting efficiency from thermal loads, and the vibration reduction due to impingement of an unsteady hot jet. In Phase II, POC plans to develop a HYSPOT prototype and experimental rig to examine the effectiveness of noise isolation, and vibration and thermal energy utilization from hot jet impingement. Benefits: As an effective means of controlling structural/acoustic noise, the HYSPOT system will have myriad civilian applications, including vibration suppression, noise minimization, and vibration cancellation in marine motors and engines, including aeroacoustic noise during landing and take-off, quieting motors for use in auditoriums, theatres, and opera houses, or ambient noise cancellation in commercial or residential buildings. The device will also have immediate commercial applications in the green energy market. Scaled up versions can be used according to electricity needs. Our HYSPOT technology definitely can address a wide range of large, exceptionally rich and diverse markets in the aerospace industry, including cabin and cockpit noise cancellation and fuselage vibration.
