In order to adapt development demand, the matching technology between HPC and LPC was analyzed and studied deeply for one of the key technologies of aero-derivative gas turbine. The technology methods were made using the combination between multi-software simulation and theory analysis method based on the design and matching characteristics of the bigger pressure ratio of HPC and LPC, The methods were applied to the new design of the fifth LPC. The rig test results meet and exceed the design requirement. The gas generator technology verification results show that the matching techonlogy is better for HPC and LPC and can provide technical foundation for aero-derivative gas turbine.
