During this analytical study, large aircraft gas turbine engine advanced bearing and seal technology was reviewed to determine those concepts which may be applicable to small, advanced, front drive turboshaft engines in the 2- to 10-lbsec airflow size. Based on this review and a study of simple mechanical arrangements which appear to be feasible, problems associated with the design of the bearings and seals in these small, advanced turboshaft engines are discussed. Finally, design approaches and test programs required to provide solutions to these problems are recommended.
