Performance evaluation of gas turbine engine on the test bed is of prime importance during the engine developmental stage. It is prudent to study the rotor dynamics, lube system, fuel system, vibratory characteristics of the engine along with its performance on the test bed. Micro Gas Turbine (MGT) Engine of 50 N thrust is being under development at CSIR-NAL. To carry out performance tests of MGT, a test bench has been developed. The test bench is equipped with (i) Lubrication system, (ii) Fuel system, (iii) Starting system, (iv) Data acquisition and measurement system. The test bed is designed to measure thrust directly using movable bed and a ‘S’ type load cell of 100 N capacity. A miniature fuel pump is used to supply fuel to engine. Air-oil lubrication system is used to lubricate the engine bearings. External compressed air supply system is developed to assist the starting of engine. DAQ and instrumentation layout has been designed and developed specific to the existing module. Test bench is configured so as to cater the measurement and online condition monitoring requirements with required sensors to measure thrust, temperature, speed and vibration. Sensors are integrated to the National Instrument data acquisition hardware. DAQ system software is developed on the LabVIEW platform.
