Energy Scavenging Unmanned Surface Vehicle for Long Range Surveillance Navy STTR FY2005 Sol No.: Navy STTR FY2005 Topic No.: N05-T021 Topic Title: Energy Scavenging Unmanned Surface Vehicle for Long Range Surveillance Proposal No.: N054-021-0129 Firm: UOV 4504 Caledon Road King George, Virginia 22485-7529 Contact: Payne Kilbourn Phone: (540) 775-9470 Web Site: www.uovehicles.com Abstract: We propose to integrate wind, solar, and motion energy technologies to create a step-change in long-endurance autonomous naval operations. Solar and wind energy can be captured and transformed into electrical energy. For maximum efficiency, we propose to convert wind energy directly into propulsion using rigid sails. Features: Rigid sails covered with solar panels that maximize the conversion from wind energy to propulsive energy. Solar panels on horizontal surfaces to maximize collection of electrical energy for hotel/sensor/communications loads and propulsion via electric motor. Battery storage for operations at night and in low wind. Electrical energy generation from propeller when under wind power. A DC motor will drive a propeller for propulsion in low-wind conditions. When wind power is providing propulsion, the propeller will turn the DC motor as a generator. The energy technology has been proven in manned vessels (wind/solar ferry in Sydney), control technology has been proven in an autonomous vessels. Objective: Detailed design of an unmanned surface vehicle that will transit long distances, maintain station indefinitely, survive severe conditions, and operate autonomously. The report will identify key vendors, develop a cost model, develop control algorithms, and demonstrate proof of concept. Benefits: The research will demonstrate the proof of concept of an energy-harvesting unmanned vehicle with the capability to carry complete sensor packages across the world's oceans, for an unlimited period of time, in all conditions. Demonstration of vehicle viability and performance will result in a new, low cost alternative for ocean surveillance for military, governmental and commercial applications. Return
