Abstract : The Chemical APU (CAPU) turboalternator assembly was tested to determine its suitability for application to advanced Army Ground Power Systems. A major test objective was that of determining the allowable continuous power rating for the alternator as a function of rotative speed. Test speeds up to 120,000 rpm in 30,000 rpm increments were evaluated. A nitrogen test rig was used as a drive which invalidated turbine data. The tests show the alternator to be suitable for use in an advanced ground unit operating on a Brayton cycle to produce 3.5 kw at 140,000 rpm. The turbine should be redesigned for gas turbine flow conditions. A Rankine cycle system could use the turboalternator in its present design at a reduced speed (80,000 rpm) to produce 3.2 kw continuous power. (Author)
