Shaft Speed Control of Laboratory Gas Turbine Engine

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...

Nonlinear Model Predictive Control of a Laboratory Gas Turbine Installation

The feasibility of model predictive control (MPC) applied to a laboratory gas turbine installation is investigated. MPC explicitly incorporates (input and output) constraints in its optimizations, which explains the choice for this computationally demanding control strategy. Strong nonlinearities, displayed by the gas turbine installation, cannot always be handled adequately by standard linear ...

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...

Design and Test of a Large Two-Shaft Gas Turbine

The largest two-shaft gas turbine in the United States has been operated in combined cycle service at the Oklahoma Gas and Electric Company Horseshoe Lake Station since May 1963. The same design unit has been operated in peaking and stand-by service at Public Service Electric and Gas (Essex, N. J.) station since December 1963. The 0.G & E. unit has a NEMA rating of 25 Mw base load. The PSEG uni...
