The work involves the study of stress behavior of a Compressor disc and its Blades. Thereafter, the Stress Sensitivities i.e. variations in stress due to changes in certain geometrical dimensions is found out. First phase of analysis consists of 2-D Axisymmetric stress sensitivity analysis of Disc cross section considering the static loads i.e. Centrifugal loads due to self-weight and blades and the changes in stress due to variation in certain geometric parameters. Next phase consists of stress analysis of a 3-D sectorial model with due consideration given to non-Axisymmetric features of the disc as well with special attention given to the blade dovetail, this time considering the gas loads i.e. loads due to air hitting the blade airfoil at high speeds and stress sensitivity calculations later on. The two results will be correlated with each other.
The above activities involve generation of Axisymmetric and 3-D sectorial models drafted on UG NX software package, which are converted to finite element mesh model using Hypermesh software. Finite Element Analysis will be carried out using general purpose ANSYS Finite element Software.
