Chapter 5 Conclusions and Recommendations
5.2 Recommendations
1. Test the performance and evaluate the benefits of larger installed capacity of gas turbine engine (C65 or C200 MGT).
2. Consider the benefits and decide whether install an inlet air cooling system to enhance the power output generated by MGT.
