Parametric Estimates of Propulsion System Maintenance Manhours.

Abstract

This thesis investigated the potential of using cost-estimating relationships (CERs) to estimate aircraft maintenance manhour requirements for propulsion systems. The performance specifications and physical parameters of a large sample of USAF turbine engines were used to develop CERs. These CERs could be applied early in the life cycle of an engine in acquisition in order to estimate future maintenance requirements and effect design configuration changes. The analysis was accomplished by the method of linear regression analysis of least squares. The CERs resulting from the regression were subjected to three tests to determine their predictive capability. A number of the CERs developed in the study displayed sufficient accuracy to be considered for application on acquisition programs.
