Description
A complete turboshaft engine genset instrumented for educational purposes. The compact jet engine gasifier core is representative of all major gas turbine types and entails an axial flow turbine stage, reverse flow annular combustor and radial flow compressor stage. This permits textbook direct analysis of the air equivalent Brayton Cycle. Students are able to apply fluids, thermodynamics, combustion and gas turbine theory to the operation of an actual engine.
The electric power generation section features a thrust driven free power turbine directly coupled to a three phase liquid-cooled electric alternator. The generation circuit is base-loaded with an integrated fixed-value resistance module. An adjustable-rate excitation current controller allows wide-range alternator loading through the complete speed range of the generation system. The electrical power system is rated to produce up to 13.1 volts, with a maximum rated power output of 2.1 kW. A fixed resistance allows system operational range to be lower for reliability. A jet thrust driven exhaust fan effectively expels heat and exhaust from the engine/generator compartment.
A fully automated engine start and health monitoring system is also included, which entails a Liquid Crystal Display status readout with a built-in cycle/hour meter.
Fourteen sensors report directly to an installed National Instruments™ DAQ platform, which entails customized LabVIEW™ displays (as depicted below). Data is configurable for output via numerous export options which include .txt and .csv file types.
The gas turbine generation system is purpose designed for this application. All components of the engine and bulk of the generation system are manufactured and assembled at TTL. This true OEM approach results in an affordable, ready to operate, supportable educational solution.
