Proceedings of the ASME Turbo Expo | Year: 2011

A procedure is outlined to determine the composite lay-out of a given baseline metallic fan blades. The vane material Titanium is replaced by Carbon Fiber composite materials. For the operating speed the baseline maximum strain in the vane is maintained and weight reduction is taken as the objective function. Three phases of optimization are suggested. In the first phase free size optimization is performed on the composite blades to determine the required topology. A layout of composites is then proposed. In the second phase based on free optimization results gauge optimization setup is illustrated for determining the thicknesses. In the third phase Ply-stacking optimization can be performed. By using composite materials substantial savings in the weight can be achieved without affecting the performance of engine blade. Copyright © 2011 by ASME. Source

Advances in Vibration Engineering | Year: 2012

Though the concept of a reaction turbine was evolved nearly 2200 years ago, a working steam turbine was demonstrated just about 120 years ago. With the discovery of Dynamo, power plants generating electricity grew in rapid numbers; together the size of the plants also grew up. During II World War, jet engines were developed using Gas turbines, Centrifugal and Axial flow compressors. Their speeds and efficiencies have increased manifold in about 60 years. These fast developments have naturally led to severe fatigue failures, particularly blades. Fatigue is essentially due to resonance and therefore researchers have initially developed blade and bladed-disk vibration theories which eventually led to fatigue life assessment methods. In this paper, a historical perspective of turbines and vibration theories leading to fatigue is presented. © KRISHTEL eMAGING SOLUTIONS PRIVATE LIMITED. Source
