1. Micro-turbine design point definition using optimization techniques
During a gas turbine development phase an important engineer task is to find the appropriate engine design point that meet all required specifications. This task can be very arduous because all possible operating points in the gas turbine operational envelope need to be analyzed, for the sake of verification of whether or not the established performance migh

3. 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
