DEVELOPMENT OF A LONG RANGE SELF-CONTAINED SUBMARINE POWER SUPPLY

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 KWhrel
Phases 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 design
Phase 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.
