STATIC STRUCTURAL ANALYSIS OF A TURBINE ROTOR BLADE OF A GAS TURBINE ENGINE IN UNTWISTED AND PRE-TWISTED CONFIGURATIONS
Keywords:
Rotor blades, Pre-twist blades, Static- Structural Analysis, Untwisted rotor bladesAbstract
In this work, we intend to study two configurations of a rotor blade, that is untwisted and pre-twisted blade, and the
deformation it undergoes on the application of different loads. Rotor blades come under heavy influences from the flow coming
from the stator blades. Three type of forces that pre-dominantly act on the rotor blade are, centrifugal, axial and tangential. The
forces act on the centroid of the blade. The modelling of the blade will be carried out using catia and static structural analysis
will be carried out in ANSYS workbench 15.0. After doing this, the blade will be given a pre-twist of 4 degree and 6 degree and
the deformation will again be analysed. Then a conclusion will be made whether which blade configuration should be installed in
a gas turbine engine for optimum efficiency and thrust
