This is a proposal that is concerned with the efficiency of                     power producing systems.  Conventional turbines operate at high                 rotational speeds which impose high stresses on the blades, so                  that the use of exotic blading materials for high-temperature,                  heightened-efficiency operation is not yet a reality.  Another                  approach is to use positive displacement expanders which                        operate at much lower speeds and have smaller diameters, with                   much lower resulting stresses.  In the proposal, helical rotor                  expanders will be studied as candidates for power cycles.                       Geometric and thermodynamic modeling will be performed.                         Application will be made to several power systems of practical                  importance.
