Abstract:
The long term goal is to advance our understanding of thermal energy extraction from the ocean thermocline using an enhanced passive thermal propulsion system. Integration of this new propulsion technology in a low drag hydrodynamic shape is expected to yield undersea glider speeds in excess of 3 Knots 5 Knots may be achievable, and persistence measured in years. Higher speeds will allow Enhanced glider operations in currents, Increased measurement rate of ocean parameters of interest, and Reduced timelines to assess parameters of interest in a fixed ocean region. Longer Persistence will provide Potential for underwater glider prepositioning with the ability to loiter while waiting for missions, Reduced logistics manning to deploy and recover vehicles and Increased measurement area per vehicle deployment. Future technology extensions of this effort will provide propulsion capability in weaker ocean thermocline regions. Hybrid vehicle designs consisting of passive energy extraction and on-board stored energy will likely result, which will increase overall mission flexibility and performance in all oceans.
