1. On the Machinability and Surface Finish of Superalloy GH909 Under Dry Cutting Conditions
GH 909 alloy is a kind of low thermal expansion superalloy with high strength and low expansion coefficient. It is mainly used for manufacturing of aero-engine turbine casings, sealing ring, vanes and other gap control parts, to improve the working efficiency and thrust of the engine as well as to reduce gas loss and fuel consumption. However, the machinabil

2. Combined Cycle Performance Evaluation and Dynamic Response Simulation
ABSTRACT Power plants operating in combined cycle present higher thermal efficiency (over 60%) and increased power generation when compared to traditional simple cycles, such as gas or steam turbines operating alone. Considering that the power plant evaluated in this paper is already operational, a further development concerning to the power plant control sy

5. Modelagem e controle de microturbina a gás do tipo split-shaft. / Modeling and control of slip-shaft gas microturbine.
The objective of the present work is the development of the model of a split-shaft micro gas turbine with feed back control system. A bibliographical review of the works on control of gas turbines indicated that there are very few works dealing this type of gas turbines. The model was developed starting from the basic geometry of the turbine and applying the

6. Control system design for a gas turbine engine using evolutionary computing for multidisciplinary optimization
Multidisciplinary optimization (MDO) is concerned with complex systems exhibiting challenges in terms of organization and scale. Thus, it is well suited to be applied to complex multivariable control design. Collaborative optimization is one approach for dealing with complex multidisciplinary optimization problems. Three MDO architectures, including collabor

7. Nonlinear control system design using variable complexity modelling and multiobjective optimization
To design controllers for complex non-linear systems usually involves the use of expensive computational models. A non-linear thermodynamic model of a gas turbine engine is used to evaluate a selection of designs for a multivariable PI controller configuration. An approach using variable complexity modelling (VCM) is introduced to allow more designs to be ev

8. Model predictive control for Francis hydro turbine generators / Controle preditivo baseado em modelo para turbo-geradores hidraulicos tipo Francis
Despite being used in the industry for more than 20 years, Model Predictive Control (MPC) has not found many applications in the field of rotating machinery controI. The majority of the applications today are chemical and petrochemical processes. However, some results obtained by other authors for the control of gas and steam turbines, suggest that its use c
