Abstract

Femtosecond laser can be used in fine processing of any material, especially for micro-nano precision machining. Cooling holes is the important technology used to improve performance of the aeroengines hot-end components such as turbine vanes and blades and is widely used in advanced aeroengines. With large quantity, small dimension and high quality requirement, cooling holes of aeroengines urgently need to develop advanced processing technology. In this paper, we first introduce advantages and research state of the femtosecond laser processing micro-holes in aeroengines. Subsequently, we discuss problems and challenges of femtosecond laser processing cooling holes in aeroengines. At last, we present that the key research areas of femtosecond laser processing cooling holes in aeroengines are as follows: interaction mechanisms between femtosecond laser and aeronautical materials should be fully explained, and system controlling methods of femtosecond laser processing should be established.
