Abstract
The purpose of aFJR project is to advance research on jet engine component technologies so that Japanese manufacturers can join more effectively in international joint-development projects on next-generation jet engines. Application of a Ceramic Matrix Composite (CMC) to low pressure turbine blade material is conducted to reduce the engine weight in the aFJR project.

Reasons for using JSS2
The CMC low pressure turbine blade was designed based on the analysis results using JSS2. The CMC blade design methodology was demonstrated experimentally.
Achievements of the Year
Figure shows the fracture analysis result of the cascade of CMC low pressure turbine blades at the moment of contact with the cascade of stator vanes. The fracture mode of the cascade of CMC blades could be analyzed.
