Integrated computational materials engineering from a gas turbine engine perspective

Durability Challenges for Next Generation of Gas Turbine Engine Materials

Aggressive fuel burn and carbon dioxide emission reduction goals for future gas turbine engines will require higher overall pressure ratio, and a significant increase in turbine inlet temperature. These goals can be achieved by increasing temperature capability of turbine engine hot section materials and decreasing weight of fan section of the engine. NASA is currently developing several advanc...

Gas Turbine Engine Behavioral Modeling

This paper develops and validates a power flow behavioral model of a gas turbine engine with a gas generator and free power turbine. “Simple” mathematical expressions to describe the engine’s power flow are derived from an understanding of basic thermodynamic and mechanical interactions taking place within the engine. The engine behavioral model presented is suitable for developing a supervisor...

Key computational modeling issues in Integrated Computational Materials Engineering

Designing materials for targeted performance requirements as required in Integrated Computational Materials Engineering (ICME) demands a combined strategy of bottom–up and top–down modeling and simulationwhich treats various levels of hierarchicalmaterial structure as amathematical representation, with infusion of systems engineering and informatics to deal with differing model degrees of freed...

A Model Driven Framework for Integrated Computational Materials Engineering

Integrated computational materials engineering (ICME) is a new approach to the design and development of materials, manufacturing processes and products. The approach proposes using a combination of modeling and simulation, data driven reasoning and knowledge guided decision making to a) speed up the development of new materials and manufacturing processes, and b) enhance the quality and time-t...
