Abstract
We will develop aerodynamic performance improvement technology and high precision aerodynamic performance prediction technology for multistage-compressore assuming an increase in relative tip clearance, corresponding to a small core engine applied to an ultra-high bypass ratio engine.

Reasons and benefits of using JAXA Supercomputer System
The number of cases of aerodynamic performance prediction of a multi-stage compressor will be very large for satisfactory results. So we can not be calculated in a realistic time using anything other than JSS2.
Achievements of the Year
The analysis including non-design points was performed for the two-stage compressor rig, and the accuracy of the numerical analysis program was confirmed. In addition, the effect of enlarging the operating range by casing treatment was confirmed using a overset grid method.
