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. The technology of the weight reduction of composite fan blade is researched in the aFJR project.

Reasons for using JSS2
The hollow composite fan blade was designed based on the bird strike simulation results using JSS2.
Achievements of the Year
Figure 1 shows the analysis result of the bird strike simulation of hollow composite fan blade. The dynamic behavior of fan blade and the strain time histories were very close to those of the demonstration test result.
Fig.1: The bird strike simulation of hollow composite fan blade (a) t = 0.3 ms
Fig.2: The bird strike simulation of hollow composite fan blade (b) t = 0.9 ms
Fig.3: The bird strike simulation of hollow composite fan blade (c) t = 1.2 ms
