Design Study for a 100-Watt Turboalternator Power Unit

Abstract

The design of a 100-watt turboalternator is investigated. Three turbine types are considered: Terry, Terry with re-entry, and side Terry with simplified buckets. Two compressed gases are considered: helium and nitrogen. Various high speed bearings are considered, with deep groove radial ball bearings, angular contact ball bearings, and three-lobe journal bearings discussed in detail. Two alternator types are considered, flux switch and rotating magnet. Turbine design details for the highest efficiency helium and nitrogen systems are determined, and their gas storage requirements are compared with the desired storage volume.
