Thermal state of a groind-use gas turbine engine stator

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...

Main Annulus Gas Path Interactions - Turbine Stator Well Heat Transfer

This paper summarises the work of a 5-year research programme into the heat transfer within cavities adjacent to the main annulus of a gas turbine. The work has been a collaboration between several gas turbine manufacturers, also involving a number of universities working together. The principal objective of the study has been to develop and validate computer modelling methods of the cooling fl...

Titanium in the Gas Turbine Engine

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...

Wireless Sensor Networks for Aerospace Applications—Thermal Monitoring for a Gas Turbine Engine

This paper reports on the development of a prototype wireless sensor network for thermal monitoring of aircraft gas turbine engines. The prototype acts as a concept demonstrator for the application at hand. Building upon the state of the art in the domain, the authors pursued a rapid prototyping approach, supported by a prototyping framework: FieldMAP. As a key property, the framework enables t...
