Applications for signal aliasing in gas turbine engine data processing

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...

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...

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...

Development and validation of a simulator for wireless data acquisition in gas turbine engine testing

Owing to its cable-free deployment, wireless sensor networks (WSNs) have drawn great attention as a new technique for industrial data acquisition. However, the harsh environment of the gas turbine engine provides a number of challenges to deployment of wireless sensors. A definitive study of the impact of harsh environments on WSNs is currently lacking, which represents an obstacle to WSN’s dep...
