Abstract—Currently, there is a scarcity of research on film-cooling of engine turbine blades, primarily due to the difficulty in accessing technical materials and the high complexity associated with designing curved surfaces. This study employs the heat flow analysis software Simcenter STAR-CCM+ to strategically plan and design the position, angle, and arrangement of heat dissipation holes for the thermal model of engine turbine blade. Subsequently, a simulation analysis is conducted to validate its heat dissipation efficiency. Additionally, experimental verification of the drilling manufacturing process is performed on aero-engine turbine blades. Based on the heat flow simulation results, a drilling model of engine turbine blade is designed for further thermal analysis of cooling efficiency. The drilling position of the workpiece is then transformed and compiled into an electric discharge machining file using the drilling process editing system integrated with the production line. Finally, an automatic production line for the drilling process is constructed to validate the performance and feasibility of the proposed thermal model for aero-engine turbine blades.
