Objective To develop and test an air-independent power system for underwater operations based on the Stirling Engine technology.The non-availability of powerful and long-endurance civilian energy sources has limited the development of surface-independent solutions for underwater working system. The results have allowed us to proceed with a real-size demonstration of a large manned, diver lock-out submarine, the "Saga I". This 300 T prototype, to be completed by august 1986, includes two V4-275R-80Kw Stirling Engines and a liquid oxygen storage system, capable of surface -independent operations for durations of up to 25 days, in actual conditions and down to 600 m, thus preparing for the next generation of underwater developments.The Stirling Engine is an external combustion engine burning fuel and pure oxygen in a pressurized combustion chamber supplying heat to a closed circuit working gas acting on a four-cylinder double action piston engine. The project consisted of building and testing a prototype power system capable of producing up to 20 Kw electricity to a depth of 200 m.
