Book Description
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.

Book Description
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...

Book Description
This report describes the work performed during the contract period and the capabilities included in the EST/BEST software system. The developed EST/BEST software system includes the integrated NESSUS, IPACS, COBSTRAN, and ALCCA computer codes required to perform the engine cycle mission and component structural analysis. Also, the interactive input generator for NESSUS, IPACS, and COBSTRAN computer codes have been developed and integrated with the EST/BEST software system. The input generator allows the user to create input from scratch as well as edit existing input files interactively. Since it has been integrated with the EST/BEST software system, it enables the user to modify EST/BEST generated files and perform the analysis to evaluate the benefits. Appendix A gives details of how to use the newly added features in the EST/BEST software system.Shah, AshwinGlenn Research CenterCOMPUTER SYSTEMS PROGRAMS; SOFTWARE ENGINEERING; COMPUTER PROGRAMMING; AERODYNAMICS; STRUCTURAL ANALYSIS; ENGINE TESTS; GRAPHICAL USER INTERFACE; PROBABILITY THEORY; DAMAGE; SYSTEMS INTEGRATION; PERFORMANCE TESTS; LOADS (FORCES)

Book Description
Many companies applying lean use a top-down approach - a person or small group defines the business process in general terms and progressively expands it into more detailed elements. This method fails when the person or small group defining the process lacks the detailed knowledge of the tasks involved to sequence them correctly. Creating Lean Corporations, by Jeffrey Morgan, however, utilizes a bottom-up approach in which the employees who perform the tasks are empowered to create and manage their own portions of the business process. Each task is defined using a task model that indicates the input-output relationships between tasks -- it dictates the sequence that the tasks should be performed within the business process. This approach is essential for creating and improving business processes that are large and complex but still efficient. The author presents three concepts in applying lean principles to an organization: (1) Hierarchies for managing large, complex systems and processes -- A template for all lean organizations is presented that allows functional (horizontal) and process-oriented (vertical) groups to be integrated into a single organizational hierarchy where command-and-control is clear and direct. (2) The use of process models to define the organization's business processes -- A standard method of process modeling that allows business processes to be represented and managed as hierarchies. The benefit of this approach is that process management is implemented in a hierarchical fashion where the level of detail increases as you move down the levels in the hierarchy. (3) A lean, bottom-up approach to business process reengineering - this works much better than traditional top-down approaches on larger, more complex business processes. This lean approach was successfully applied at a major automotive manufacturing company and was awarded the Charles F. "Boss" Kettering Award as one of the most important technological innovations in 2000. This book is for business process managers (especially lean leaders) who seek to reengineer their business processes using lean principles.

Book Description
The 28th EG-ICE International Workshop 2021 brings together international experts working at the interface between advanced computing and modern engineering challenges. Many engineering tasks require open-world resolutions to support multi-actor collaboration, coping with approximate models, providing effective engineer-computer interaction, search in multi-dimensional solution spaces, accommodating uncertainty, including specialist domain knowledge, performing sensor-data interpretation and dealing with incomplete knowledge. While results from computer science provide much initial support for resolution, adaptation is unavoidable and most importantly, feedback from addressing engineering challenges drives fundamental computer-science research. Competence and knowledge transfer goes both ways. Der 28. Internationale EG-ICE Workshop 2021 bringt internationale Experten zusammen, die an der Schnittstelle zwischen fortgeschrittener Datenverarbeitung und modernen technischen Herausforderungen arbeiten. Viele ingenieurwissenschaftliche Aufgaben erfordern Open-World-Resolutionen, um die Zusammenarbeit mehrerer Akteure zu unterstützen, mit approximativen Modellen umzugehen, eine effektive Interaktion zwischen Ingenieur und Computer zu ermöglichen, in mehrdimensionalen Lösungsräumen zu suchen, Unsicherheiten zu berücksichtigen, einschließlich fachspezifischen Domänenwissens, Sensordateninterpretation durchzuführen und mit unvollständigem Wissen umzugehen. Während die Ergebnisse aus der Informatik anfänglich viel Unterstützung für die Lösung bieten, ist eine Anpassung unvermeidlich, und am wichtigsten ist, dass das Feedback aus der Bewältigung technischer Herausforderungen die computer-wissenschaftliche Grundlagenforschung vorantreibt. Kompetenz und Wissenstransfer gehen in beide Richtungen.
