Abstract

Power conversion units for the proposed Strategic Defence Initiative (SDI) objectives must be capable of supplying very high power for short periods, must start (and restart) rapidly, and must be as compact and lightweight as possible. Open cycle gas turbines offer attractive potential for such applications. Typical proposed turbine designs are of the axial throughflow type, utilizing combinations of hydrogen (H₂) and oxygen (0₂) as the working fluid. As an alternative, an analytical model of a multistage radial outflow Ljungstrom turbine utilizing H₂-0₂ (combinations) as the working fluid is presented. Families of such turbines are generated, using design constraints consistent with SDI objectives and modern turbine design. Comparisons are made with multistage axial throughflow machines. It is shown that Ljungstrom type configurations indeed offer an attractive design alternative for SDI missions.
