Brittle Materials Design, High Temperature Gas Turbine Rotor Blade Development and Turbine Modification. Volume 3

Abstract

Ceramic rotor blade development with performance simulation by computer and a demonstration of ceramic stator vanes operating in an advanced version of a stationary turbine engine were part of the original project objectives which were only partially completed. While a reorganization of program priorities placed emphasis on stator vane design, analysis, and static rig testing in lieu of the blade development and turbine demonstration tasks, the Westinghouse Research and Development Laboratories did develop a comprehensive three dimensional finite element computer code (WISEC) for the analysis of complex structures like the turbine blade. DARPA project funds were used for the development of many critical sub-routines contained within WISEC. A family of three dimensional, mixed isoparametric elements evolved for the modeling of a variety of loading conditions in both stress and heat conduction analyses. The code possesses an ability to: (1) Analyze materials with temperature dependent properties; and (2) Handle anisotropic as well as isotropic materials.
