Applied Aerodynamics Drag Prediction Workshop - NASA
2001年6月10日 · The DLR-F4 test cases have been chosen that address a subsonic wing/body transport configuration flying at subsonic through transonic speeds. The prediction of drag polar and drag rise will be particularly emphasized. A statistical framework will be used to assess the comparisons within the computational results and with the test results.
