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.
Goal

Use of the Supercomputer
The CMC low pressure turbine blade was designed based on the analysis results using JSS2. The next step is to demonstrate the CMC blade design methodology and to validate the analysis results using demonstration test results.
Necessity of the Supercomputer
It is necessary to use JSS2 to handle large analysis models in the present cases.
Achievements of the Year
Figure 1 shows the analysis result of the cascades of CMC low pressure turbine blades at the moment of contact with the cascade of stator vanes. It was found that the cascade of CMC rotor blades were fractured within the time specified.
