The approach to validation and component analysis involves the following steps: determination of the statistical nature and source of fracture in a high strength, NiAl single crystal turbine blade material; measurement of the failure strength envelope of the material; coding of statistically based reliability . Reliability analysis of single crystal NiAl turbine blades As part of a co-operative agreement with General Electric Aircraft Engines (GEAE), NASA LeRC is modifying and validating the Ceramic Analysis and Reliability Evaluation of Structures algorithm for use in design of components made of high strength NiAl based intermetallic materials. NiAl single crystal . Buy Reliability analysis of single crystal NiAl turbine blades (SuDoc NAS ) by NASA (ISBN:) from Amazon's Book Store. Everyday low prices and free delivery on eligible : NASA. NiAl single crystal alloys are being actively investigated by GEAE as a replacement for Ni-based single crystal superalloys for use in high pressure turbine blades and vanes. The driving force for this research lies in the numerous property advantages offered by NiAl .

  NiAl alloys to compete with single crystal Ni-base superalloys in high temperature creep and rupture strength have been developed and characterized. In addition, NiAl turbine airfoils with . This study describes a finite element creep analysis of a first stage turbine blade using a calibrated creep material model, and compares the calculated untwist to records kept by the operator. The creep model used in this study is a physics based model using the microstructural properties of the blade alloy, and is calibrated using a single. Very detailed information on the analysis of blade strength and vibration modes. The book provides an overview of standard turbine blade designs and manufacturing methods. The book covers blades for a range of steam turbines and not specifically for RPM turbine-generator systems.
