A summary of First Aerodynamics Prediction Challenge (APC-I) is presented. The APC-I is a domestic CFD prediction workshop that was held in Japan on July 3, 2015. The test cases include verification benchmarks, aerodynamic prediction of NASA-CRM, and its wake flow prediction. One of the differences between APC-I and the previous Drag Prediction Workshop (DPW) is the inclusion of aeroelastic effects. We compare the CFD results with JAXA’s wind tunnel measurements. There were 14 participants from government, academia, industry, and commercial. The CFD results submitted from the participants are compared with the measurements, and emerged challenges are shown in this paper.
