Unit I
INTRODUCTION 9
Overview of the different operational regimes for gas turbine applications: base load, peak load, standby and backup operations, alongside their individual operational requirements. Fundamentals of Creep and Fatigue damage mechanisms. Material, design and operational parameters that affect creep and fatigue. Experimental and test procedures to characterise creep and fatigue damage.
Unit II
DESIGNING FORCES
Loads/forces/stresses in gas turbine engines: loads – rotational inertia, flight, precession of shafts, pressure gradient, torsion, seizure, blade release, engine mountings and bearings-Discussion of major loadings-rotating components and pressure casing components.
Unit III

Unit IV
BLADE DESIGN 9
Design of discs, blades. Illustration of magnitude stresses in conventional axial flow blades- simple desk-top method -effects of leaning the blade. Design of flanges and bolted structures. Leakages through a flanged joint and failure from fatigue.
Unit V
BLADE VIBRATIONS AND DAMAGE MECHANISMS 9
Natural frequencies turbomachine blades. Blade twist, centrifugal stiffening, Sources of blade excitation, Stationary flow disturbance, rotating stall and flutter. Campbell diagram and troublesome resonances. Allowances for temperature, pre-twist and centrifugal stiffening. Methods for dealing with resonances.
Course Outcomes:
At the end of the course the students would be able to
- Differentiate the operational regimes and requirements related to different gas turbine applications.
- Describe and distinguish the design requirements and loads encountered by gas turbine components during normal operation;
- Analyse, evaluate and assess the loads, stresses, failure criteria and factors of safety used in gas turbine engines
- Evaluate impact of vibrations on design and operation of gas turbine;
- Assess the creep and fatigue damage of gas turbine components based on design and operational parameters
