Аннотация
The work is devoted to demonstrating the effectiveness of the energy method for predicting self-oscillations (flutter) using the example of a monowheel of the 1st stage of a low-pressure compressor of a gas turbine engine. Flutter was detected during engine tests by the monowheel strain gauge method and using contactless diagnostic tools. Using an engineering calculation technique based on the energy method, the monowheel was detuned from flutter by re-profiling the blades. The calculated distribution of the work of non-stationary aerodynamic forces on the elastic movements of the blade during the oscillation cycle according to its own shape allows the designer to focus on the contribution of certain areas of the blade during detuning from the flutter and minimize the loss of aerodynamic parameters. In this work, for the first time in the domestic engine industry, an experimental verification of the absence of a flutter of a computationally tuned compressor impeller was successfully carried out using the energy method when testing it as part of an engine. The developed technique makes it possible to obtain a significant economic effect from reducing the volume of tests and eliminating the risk of engine failure.
