COST ESTIMATING RELATIONSHIPS FOR TURBOJET ENGINES.

Abstract

Cost estimating relationships for turbojet engine procurement costs are derived by the use of linear regression. The basis for this paper is the historical cost of 14 different model turbojet engines. Estimating relationships are developed for two cases; cumulative average engine cost, and cost per pound of engine. For the first case, specific fuel consumption was found to be the best explanatory variable. For the second case, specific weight proved to be the most suitable explanatory variable. The uncertainty associated with either estimating relationship is large because, in both cases, only about 75 percent of the variation in cost is explained. (Author)
