Research Field

Aero-engine / Gas Turbine

Research Overview

I have extensive experience in researching aero - engines and gas turbines, with a focus on three main areas: the design of high - load compressors, numerical simulation of three - dimensional viscous flow in turbomachinery, and the overall design of engines.

In the field of key technologies, I have conducted research on the design of high - load vaneless counter - rotating compressors and the design and verification of two - stage centrifugal compressors. These studies aimed to improve the performance and efficiency of relevant components.

Regarding overall engine development, I served as the technical director for the development of a 100kW gas turbine project. In this role, I led the team through the entire development process, from initial design to the final stage of experimental verification, successfully validating the feasibility of the gas turbine design.
