3. Introduction
• Gas Turbine Research Establishment is one of the pioneering Research and
Development Organizations under the Ministry of Defence, Government of India.
• Design and develop gas-turbine engines for military applications
• advanced research work in the area of gas-turbine sub-systems
4. Company Introduction
• Gas Turbine Research Establishment - DRDO
• Took birth in Kanpur in 1959 with 8 Engineers/Scientists and about 20 Technicians
• First developed centrifugal type gas turbine engine of 1000 kg thrust.
• Moved to Bangalore, brought under the banner of DRDO, and was re-named as Gas
Turbine Research Establishment (GTRE) in November 1961
6. Vision and Mission
Vision
• To be a centre of excellence for aero gas turbine research and development of related
technologies.
Mission
• To Design, develop and integrate advance technologies, state of art aero gas turbine engines and
their derivatives for defence forces.
•
7. Working of gas Turbine
• A gas turbine is a type of internal combustion engine that converts the
chemical energy of fuel into mechanical energy by burning the fuel inside the
engine.
• The basic working principle of a gas turbine engine involves three main
components: the compressor, the combustor, and the turbine.
9. Mechanical Components
• A Rotating Gas Compressor
• A Combustor
• A Compressor – Driving Turbine
• Propelling nozzle
• afterburner
10. Compressor
• Axial Compressors are used in gas turbines
• 2 stages – High pressure and Low pressure
• High pressure has 6 stages
• Low pressure has 3 stages
11. Combustion Chamber
• The air from the compressor is mixed with fuel and ignited to produce a high-temperature,
high-pressure stream of gases that drives the turbine.
• Located between the compressor and the turbine
• The chamber is lined with heat-resistant materials to withstand the high temperatures
generated during combustion.
• Injection of fuel by a spark or a pilot flame, which initiates the combustion reaction.
12. Propelling Nozzle
• Converts the high-velocity, high-pressure gases from the combustion chamber into a high-
speed jet that generates thrust and propels the aircraft or other machinery.
• located at the rear of the engine and consists of a converging section, where the cross-
sectional area decreases, followed by a diverging section, where the cross-sectional area
increases.
13. Afterburner
• to increase their thrust output in certain situations, such as takeoff or high-speed flight.
• located between the turbine and the propelling nozzle
• consists of a combustion chamber that injects additional fuel into the exhaust gases and ignites
them, producing an additional burst of high-temperature, high-pressure gases that exit the
nozzle and provide additional thrust.
• increase the thrust output of a gas turbine engine, typically by 30-50%
• Decreses Fuel Efficiency
14. Task Performed
The internship at GTRE was an excellent opportunity for me to
learn and develop various skills related to gas turbine technology
• Performance Analysis of Turbine Blades
• Documentation and Reporting
• Literature Review
• Collaborative Work
• Understanding Workplace Culture
15. Specific Outcomes
• Performed non destructive testing on low pressure turbine
blades
• Non destructive testing involved 4 types of methods
• Fluorescent penetration testing – fluorescent liquid
• Magnetic particle testing – magnetic particle oil
• Ultrasonic testing – peizoelectric substance
• Radiography - XRAY
16. Conclusion
• Internship gave an exposure to professional activities and Experience
• A bright study was made on Gas Turbines, Design, working and its environment.
