Abstract: Euler/RANS-based CFD methods have been rapidly developed and widely used in aeronautics since the 1980s, making remarkable achievements and playing an important role in aircraft development and aerodynamic research. This article reviews the achievements of CFD in military and civil aeronautics in the past four decades and analyzes its shortcomings, particularly the problem in separation flow simulation due to the turbulence modeling. The development of aeronautics CFD is discussed from the perspectives of turbulence models and numerical schemes. Finally, a brief conclusion and suggestions on future development are presented.

Key words: aeronautics, CFD, aerodynamics, aircraft, turbulence
