Two hydrocarbon fueled internal combustion UUV power sources incorporating a high-speed turbo-alternator are described, and their performance variation with operating depth and total energy is discussed. Turbine performance data is also discussed. These systems require only the refilling of tanks without disassembly between runs. They have overall system specific energies 3 to 4 times that of silver-zinc batteries. The hydrocarbon selected is JP-5, which is a typical naval jet engine fuel with a flash point suitable for shipboard handling. The two oxygen souces considered are 3000 psi gaseous oxygen and 60 % hydrogen peroxide aqueous solution. The systems described attain specific energies of 300 and 464 Wh/kg and energy densities of 261 and 162 Wh/L. Significant improvements are possible through more compact energy conversion and ancillary component packaging.
