Life and Utilization Criteria Identification in Design (LUCID). Volume 1

Abstract

In early gas turbine engine conceptual design, a complex interactive aircraft/engine design effort is conducted. The primary objective of the Life and Utilization Criteria Identification in Design (LUCID) Program was to develop and demonstrate techniques which will aid in identifying, during conceptual design, balanced and consistent performance and life capability goals with which to proceed to engineering development. In Volume I, a methodology for quantifying relative life/performance trades during the conceptual design phase of gas turbine engine development is presented. As part of this methodology, a computer-aided design system employing regression techniques has been developed and demonstrated. Major elements of this system are performing satisfactorily. However, certain component subroutines are exhibiting unacceptable error levels. Further effort is required in this innovative application of standard regression techniques.
