Abstract
The influence on the aerodynamic performance by aerodynamic interaction between a rotor and a wing on a compound helicopter have been investigated through a numerical simulation and an experiment.

Reasons for using JSS2
There is a large number of computational case, and a computational resource is required to obtain the simulation results promptly.
Achievements of the Year
As a pre-test prediction of the aerodynamic perfomance for a wind-tunnel test on the rotor-wing interaction, numerical simulations are performed based on the configuration of the test models. The numerical simulations of the rotorcraft are based the moving overlapped grid as shown in Fig. 1. The prediction results assisted the determination of the test condtion and good correlation with the test data are observed.
