The report describes the technical effort to develop: (1) geometry recipes for nozzles, inlets, disks, frames, shafts, and ducts in finite element form, (2) component design tools for nozzles, inlets, disks, frames, shafts, and ducts which utilize the recipes and (3) an integrated design tool which combines the simulations of the nozzles, inlets, disks, frames, shafts, and ducts with the previously developed combustor, turbine blade, and turbine vane models for a total engine representation. These developments will be accomplished in cooperation and in conjunction with comparable efforts of NASA Glenn Research Center. McKnight, R. L. and Maffeo, R. J. and Schrantz, S. and Hartle, M.

A component specific modeling software program has been developed for propulsion systems. This expert program is capable of formulating the component geometry as finite element meshes for structural analysis which, in the future, can be spun off as NURB geometry for manufacturing. COSMO currently has geometry recipes for combustors, turbine blades, vanes, and disks. Component geometry recipes for nozzles, inlets, frames, shafts, and ducts are being added. COSMO uses component recipes that work through neutral files with the Technology Benefit Estimator (T/BEST) program which provides the necessary base parameters and loadings. This report contains the users manual for combustors, turbine blades, vanes, and disks. Mcknight, R. L. and Maffeo, R. J. and Schwartz, S. Unspecified Center...

Structural Analysis Systems: Software—Hardware Capability—Compatibility—Applications, Volume 3 is a practical guidebook on structural analysis systems and their applications. It provides detailed information about a specific software, its postprocessor capabilities and limitations, computer-aided design connection, and compatibility with the most common computers. Several practical examples from industry with computer and user cost are given. This volume consists of 20 chapters and begins with a description of ALSA, a general purpose finite element computer program for accurate large order structural analysis. The discussion then turns to BEFE, a general purpose program for the static analysis of structures and solids using the finite element method, the boundary element method, or a combination of the two. The following chapters focus on other computer programs such as BEWAVE, CASTEM, FEMFAM, FEMPAC, and OSTIN for applications ranging from finite element analysis to seismic analysis. This book will be a useful resource for practitioners in scientific and industrial disciplines such as mechanical or civil engineering, informatics, applied mathematics, and computer science.
