Abstract Hollow turbine blade is one of the key parts which restricts the development of high performance aeroengine.
Aiming at the issue of low pass ratio of turbine blade, the shape and material properties monitoring methods are
reviewed based on the investigation of investment casting process in this paper. Moreover, the development trends of next
generation turbine blade are discussed from the aspects of materials, structures, and manufacturing process respectively.
The analysis shows that ceramic matrix composites are expected to be widely used on turbine blade in the future.
