R&D study of Mitsubishi Regional Jet (MRJ) has been conducted since 2003, under the auspice from NEDO. In this study, various fundamental research items for aircraft development including advanced aerodynamics, noise study and multidisciplinary design optimization (MDO) have applied to the design of MRJ. In these R&D activities, state-of-the-art technology developments have been pursued by strong university-government-industry cooperation. This report presents application of CFD and MDO technologies to MRJ design as an example of R&D activities.
