Information × Registration Number 0210U001922, 0109U007810 , R & D reports Title Determination of natural frequency spectrum and fields of relative displacements and stress in built-up blade wheels of gas turbine with monocrystalline uncooled blades. popup.stage_title Head Vorobiev Yu.S., Registration Date 21-05-2010 Organization A.Podgorny Institute for Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2 Free vibrations of banded gas-turbine engine impellers with monocrystalline uncooled blades with orientation of crystallographic axes [001] or [111] have been investigated. The problem is solved with the finite-element method in three-dimensional arrangement using PC ANSYS. Methods and model of an impeller are developed, numerical analysis of influence of type of material, orientation of crystallographic axes of monocrystals, type of banded connections and temperature fields on natural frequency spectrum, forms and distribution of relative stress intensities is carried out. Practical recommendations in choosing construction material. Results can be applied at enterprises of turbine construction.
