Simulation Tool Development for Jet Engine 

This poster presents the creation and utilization of a simulated model of the SR-30 turbojet engine for student use, based on mathematical models that adequately describe the internal processes of the engine. The application of the model extends outside the classroom education purpose, with the perspective of exercising the generic model to predict operation at off-design points and adaptation of model to other jet engines. Model predictions could be used to generate performance data points for compressor and turbine maps to be build based on experimental data.

This is a result of a directed undergraduate research CO-OP study assigned to the main student author. The scope of work is to develop appropriate simulation models for thermo-fluid processes in the jet engine, calibrate the models with existing thermodynamic data obtained on the SR30 jet engine (operational in the Thermodynamics Lab) and then apply such calibrated models to predict adaptation of jet engine to operation based on using a carbon neutral or regenerable fuel (such as hydrogen or biodiesel), operation at off-design points. 

This project is the first step in a broader model-based design and project-based learning initiative that is being developed in response to challenges presented by the School of Engineering development of new programs and expansion of the graduate program in mechanical engineering. The need and the urgency in developing model based learning is tied to the relatively low cost of conducting research based on simulation models compared to the much higher cost associated with purchasing lab equipment and experimental prototypes for  experiential learning.

Different approaches of simulation models will be explored - including: models based on zero dimensional thermodynamics, models matching experimental data, spreadsheet based predictive models based on turbine and compressor maps (using generic maps or actual prototype maps) software models have been created in MATLAB - SIMULINK platform.

 

The SR-30 Turbojet Engine is a common, small turbojet engine used for testing and educational purposes. Adding a calibrated simulation model for the engine can add valuable insight to an experiment and enhance the student learning experience by adding opportunities for analysis.

Our research intends to create a one-dimensional computer simulation of the turbojet engine, which will be able to simulate the physical parameters of the actual run. The approach can also be of use for simulating other small turbojet engines, which are relevant for small-scale aerial vehicles and for shaft power in industrial applications. Application of the model include running at off-design conditions and exploring adaptation to use different fuel including renewables. Design of the model has in mind the integration in a model-based control simulation.
