Gas-Dynamic Modeling of Gas Turbine Engine Components Collaborative Workflow

The aim of this article was the development of the gas-dynamic models allowing to calculate the working processes of the gas turbine engine (GTE) in the compressor, in the combustion chamber and in the turbine at the same time. The possibilities of software systems for complex engine workflow modeling are specified. The advantages and disadvantages of the presented methods are specified. The re...

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...

CAPABILITY OF 718Plus FOR STRUCTURAL GAS TURBINE ENGINE COMPONENTS (PREPRINT)

Recent developments from the cast 718Plus® Metals Affordability Initiative (MAI) program will be presented and discussed. The objective of the program is to investigate and enable the use of 718Plus® (hereinafter referred to as 718Plus) in the form of investment castings by (1) increasing the allowable operating temperature by about 75°F as compared with conventional cast Alloy 718 and (2) achi...

Learning Multi-dimensional Functions: Gas Turbine Engine Modeling

This paper shows how multi-dimensional functions, describing the operation of complex equipment, can be learned. The functions are points in a shape space, each produced by morphing a prototypical function located at its origin. The prototypical function and the space’s dimensions, which define morphological operations, are learned from a set of existing functions. New ones are generated by ave...
