Development Trend of Cooling Technology for Turbine Blades at Super-High Temperature of above 2000 K

Aeroengines and heavy-duty gas turbines are the core power equipment in field of national defense energy. Their research development (R&D) level manufacturing represent status a country’s heavy industry world. The common cooling technologies turbine blades including impingement cooling, film effusion layer pin fin rough ribs were introduced this paper. With continuous improvement efficiency performance aeroengines turbines, inlet temperature increases gradually every year; will be exposed to higher temperatures future as break 2000 K. In order ensure safe operation under severe super-high working conditions, technology must developed emphatically. This paper first reviews blade points out focuses. trends next-generation for above K summarized from several aspects: innovative excavation high-efficiency composite configuration, multi-objective cooperative structure optimization design based on 3D printing, an artificial intelligence algorithm, tapping potential new media heat pipes, integrated thermal protection with insulators, application low-resistance surface dimple cooling. summary can provide reference researchers technology.
