Blade flutter of modern jet engines and gas turbines is one of the main issues that engine designers have to face. The most used numerical method that is employed for flutter prediction is the energy method. Although a lot of papers are devoted to the analysis of different blade wheels, this method was rarely validated by experiments. Typical mesh size, time step, and various modeling approaches that guarantee reliable flutter prediction are not commonly known, whereas some examples show that predictions obtained through nonvalidated codes can be inaccurate. In this paper, we describe the implementation of the energy method that is employed in the design of jet engines and gas turbines in Gas Turbine Engineering Research and Production Center “Salut”. Flutter onset predictions are obtained for two wheel models representing two stages of the same compressor. For the model of a blade wheel, blade oscillations in a natural mode are specified and unsteady aerodynamic analysis is conducted. Then the work done by unsteady pressure over the oscillation cycle is calculated, and based on its sign the flutter prediction is made. Numerical results are verified by compressor and full engine flutter test data. Tests were conducted in two operating regimes: stable and flutter. It is shown that the prediction of flutter onset is rather reliable so that the modeling approaches presented in this paper can be used by other researchers for the flutter analysis of industrial compressor and turbine blades. |
