Aeroelastic Behaviour of a 3.5-Stage Aircraft Compressor Rotor Blades Following a Bird Strike
Autor: Lyubov Vladimirovna Kolodyazhnaya, V. Gnesin, Leszek Kubitz, Romuald Rzadkowski
Publikováno v: Journal of Vibration Engineering & Technologies. 6:281-287
This paper analyses unsteady forces acting on rotor blades in a 3.5 stage compressor following a bird strike. The strike was modelled by partially blocking the engine inlet. An in-house code was used to calculate 3D unsteady non-viscous flow of ideal

Publikováno v: Journal of Vibration Engineering & Technologies. 6:297-308
This paper analyzes unsteady forces acting on rotor blades in a 7.5-stage compressor with full admission. An in-house code was used to calculate 3D-unsteady non-viscous flow of ideal gas through a 7.5-stage compressor, using the Godunov–Kolgan meth

Numerical Analysis of the Three-Dimensional Nonstationary Flow of Ideal Gas in the Last Stage of Turbine Machine Taking into Consideration the Nonaxisymmetric Exhaust Pipe Branch
Autor: Lyubov Vladimirovna Kolodyazhnaya, Vitaly Gnesin, Romuald Rzadkowski
Publikováno v: NTU "KhPI" Bulletin: Power and heat engineering processes and equipment.
A problem related to the forecast of the aeroelastic behavior and aeroelastic instability of blades (in particular self-oscillations, flutter, and resonance vibrations) becomes of great importance for the development of high-loaded compressor and ven

Numerical modelling of the aeroelastic behaviour and variable loads for the turbine stage in 3D transonic flow
Autor: Lyubov Vladimirovna Kolodyazhnaya, Romuald Rzadkowski, V. Gnesin
Publikováno v: Scopus-Elsevier
In this study presented the algorithm proposed involves the coupled solution of 3-D unsteady flow through a turbine stage and the dynamics problem for rotor-blade motion by the action of aerodynamic forces, without separating the outer and inner flow
