T/BEST: a computer code for assessing the benefits of advanced aerospace technologies

A computer software named T/BEST, Technology Benefit Estimator, has been developed to provide a formal method to assess advanced aerospace technologies and quantify the benefit contributions for prioritization. An open-ended, modular approach is used to allow for upgrade and insertion of advanced technology modules. T/BEST's software framework, beginner-to-expert operation, interface architecture and key analysis modules are discussed. In this paper, selected features and applications of T/BEST are demonstrated. Sample cases pertaining to structural analysis of fan and compressor blades made of titanium and composite are presented. The performance of hot and cold composite fan blades is also discussed. The cost required to manufacture titanium and composite fan blades is estimated. © 1997 Elsevier Science Limited
