“…How far one could currendy get with the flow simulation codes with respect to accuracy in predicting baseline performance coefficients can be deduced from the results of the AIAA CFD Drag Prediction Workshop Rakowitz et al [6] who presented the achievements of the codes FLOWer and TAU applied at Airbus Germany. Therefore aerodynamic simulation is asked to deliver basic performance figures like drag and lift for cruise and those for start and landing conditions.…”

“…The workshop was a follow-on to the first Drag Prediction Workshop (DPW I) held in June 2001. [1][2][3][4][5][6] The objectives for both workshops were (1) to assess state-of-the-art computational methods as practical aerodynamic tools for aircraft force and moment prediction, (2) to impartially evaluate the effectiveness of existing computer codes and modeling techniques, and (3) to identify areas needing additional research and development.…”

“…Several of the participants presented their DPW-I results [8][9][10][11][12][13] at a well-attended special session of the 2002 AIAA Aerospace Sciences Meeting and Exhibit in Reno, Nevada. The interest generated by the DPW-I naturally led to the planning and organization of the Second AIAA Drag Prediction Workshop (DPW-II).…”

Results from the Fourth AIAA Drag Prediction Workshop are summarized. The workshop focused on the prediction of both absolute and differential drag levels for wing-body and wing-body/horizontal-tail configurations of the NASA Common Research Model, which is representative of transonic transport aircraft. Numerical calculations are performed using industry-relevant test cases that include lift-specific flight conditions, trimmed drag polars, downwash variations, drag rises, and Reynolds-number effects. Drag, lift, and pitching moment predictions from numerous Reynolds-averaged Navier-Stokes computational fluid dynamics methods are presented. Solutions are performed on structured, unstructured, and hybrid grid systems. The structured-grid sets include point-matched multiblock meshes and overset grid systems. The unstructured and hybrid grid sets comprise tetrahedral, pyramid, prismatic, and hexahedral elements. Effort is made to provide a high-quality and parametrically consistent family of grids for each grid type about each configuration under study. The wing-body/horizontal families comprise coarse, medium, and fine grids; an optional extrafine grid augments several of the grid families. These mesh sequences are used to determine asymptotic grid-convergence characteristics of the solution sets and to estimate grid-converged absolute drag levels of the wing-body/horizontal configuration using Richardson extrapolation.
