Energy Scavenging Unmanned Surface Vehicle for Long Range Surveillance

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.
