Objective
Extensive experimental and theoretical work was done on gas turbines to develop new methods of component monitoring. Acoustic imaging software was used to stimulate rotor stage fouling, individual rotor blade foulding, individual rotor blade twisting and stator blade restaggering.
Gross component failures and local faults within the engine component were successfully identified. These included minor compressor fouling and individual blade damage. This capability was significant as it had not previously been realized by any other non-intrusive gas turbine health monitoring system.
Gas turbines are used in 2 major applications -aero-propulsion and shaft power generators. In both categories, the running costs are high and maintenance of a high overall thermal efficiency is very important. It is essential to detect and rectify faults prior to engine failure.
Advanced techniques have been developed and tested, which are based on acoustic and thermodynamic measurement, which combine with conventional dynamic techniques - such as shaft displacement and casing vibration - to overcome the limitations of today's gas turbine health monitoring systems.
THE MAIN TECHNICAL OBJECTIVES OF THIS RESEARCH IS TO DEVELOP A PROTOTYPE HARDWARE AND SOFTWARE SYSTEM INTENDED FOR ON-LINE MONITORING OF OPERATING GAS TURBINES. BASICALLY THE WORK WILL INCLUDE A SIMULTANEOUS APPROACH BASED ON DYNAMICS AND THERMODYNAMIC DESIGN; ESPECIALLY FOR DYNAMICS, NOVALTY WILL LIE IN FACT THAT NOISE AND VIBRATION IMAGING TECHNIQUES WILL BE USED.
THIS WILL LEAD TO NEW AND ROBUST DISCRIMINANTS, FOR A POWERFUL DIAGNOSTIC METHODOLOGY. SUCH DISCRIMINANTS WILL BE DIRECTLY RELATED TO THE SPATIAL STRUCTURE OF THE MEASURED FIELDS (ON SPECIFIC ACOUSTIC-VIBRATION ARRAYS).THEIR CORRELATION WITH THE ENGINE OPERATION CONDITION AND THE THERMODYNAMICS EFFICIENCY, WILL BE STUDIED THROUGH BOTH ANALYTICAL AND EXPERIMENTAL WORK.
