Description:
Overview: - The problem of this research work is formulated by Gas turbine research establishment, Bangalore (DRDO Lab) and involves working under the guidance of Sri T N Suresh, Scientist ‘G’ & Technical Director at GTRE Bangalore and Dr. Sanjoy K Ghoshal, Associate Professor, Dept. of Mechanical Engineering. IIT(ISM) Dhanbad. In particular the research problem has three distinct objectives. One of the aim of the project is to estimate the burst strength of the gas turbine disc and estimate the burst margin. Burst margin is the margin of safety beyond maximum operating speed within which disc will not fail. Further the work is extended to predict the critical speed of the disc under plausible operating condition within the speed range decided on the basis of burst speed analysis. Moreover, the healthy and cracked disc has been analyzed with an aim to differentiate between them and to develop a basis to detect the crack in rotating disc.
Description:
The objective of the project is to carryout 3D finite element analysis of the dovetail and fir-tree attachment region of disc/blade assembly of an aeroengine. Software package ANSYS has been used for analysis purpose. Attention of this study is devoted to the mechanisms of damage of the turbine disc and to examine the effect of critical geometrical features, such as number of teeth, flank length and flank angle upon the stress field in the disc. In the analysis a finite element model has been created for the purpose of assessing the stress at the joint region connecting the blade to the disc slot and to identify the failure region in turbine disc-blade assembly. Finally, an optimum design limit has been proposed for above mentioned critical geometrical features.
