Objective To design and to test a long range self-contained submarine power supply with peak electric power capabilities above 100 KWhrel and capacity well above 1,000 KWhrelPhases 1 and 2 results have shown that:-the combustion chamber should be designed by making an extensive use of aeronautic methodology: the minimum thermal output should stand around 150 to 200 KWthermal;- it is necessary to recirculate exhaust gases in order to maintain gas temperature within acceptable ranges (viz. below 2,000 k);- an organic Rankine cycle machine will yield a 20% overall thermomechanical conversion efficiency;- full liquefaction of combustion gases is possible with conventional heat exchanger configurations working at 60 bars, 15 C average liquefaction conditions.The whole project is divided into 4 phases:Phase 1:feasibility study of a liquid methanol-pressurized oxygen combustion chamber, coupled with an organic Rankine Cycle for electricity generation and a heat exchanger configuration leading to full liquefaction of the combustion gases.Phase 2:laboratory tests of the liquefaction system.Phase 3:full scale tests of combustion chamber designPhase 4:full scale tests of the self-contained submarine power supply both under onshore and offshore conditions.Only phases 1 and 2 are part of the contract TH 15030/82.
