<p>A bubble-free underwater propulsion system produces energy in the form of gas and/or steam from the catalytic decomposition of hydrazine as a hydrazine/water mixture, which is passed to a turbine. The turbine exhaust gas is subjected to condensation, the soluble condensate then being pumped into the sea while a compressor forces remaining gas back into the hydrazine tank where it is available for propelling the hydrazine or hydrazine/water mixture. The fuel may be a mixture of 65% hydrazine - 35% water, or hydrazine monohydrate, or pure hydrazine. The last-mentioned may be mixed with the water necessary to give bubble-free operation just before entering the gas-generator. The system is free of the limits on operating range imposed by battery size and weight if using electric propulsion to achieve bubble avoidance.</p> |
