MGT-70(3) Experimental Test Results

Abstract

MGT-70(3) gas turbine is the recent upgraded version of MGT-70 gas turbine family introduced by MAPNA Turbine Engineering & Manufacturing Co. (TUGA). Due to the vast upgrade regards to its predecessor engine, MGT-70(3) required to be tested extensively in order to examine the functionality of the engine as well as verification of the CFD calculations. Therefore, a detailed component test designed and implemented. A set of large number of sensors, both in quantity and type, utilized in almost all stages of turbine, compressor and combustion chamber. Testing both the static and dynamic behaviour of the engine was favourable. Thermocouples and pressure sensors have been used for static measurements while 5-Hole Probes and strain gauges for dynamic behaviors. A BTT/BTC measuring system is also installed on some stages for BTT/BTC measurements. The results demonstrated that all performance targets have been met and even exceeded in some indexes.
