Book excerpt: An unstructured-grid Navier-Stokes solver was used to predict the surface pressure distribution, the off-body flow field, the surface flow pattern, and integrated lift and drag coefficients on the ROBIN configuration (a generic helicopter) without a rotor at four angles of attack. The results are compared to those predicted by two structured- grid Navier-Stokes solvers and to experimental surface pressure distributions. The surface pressure distributions from the unstructured-grid Navier-Stokes solver are in good agreement with the results from the structured-grid Navier-Stokes solvers. Agreement with the experimental pressure coefficients is good over the forward portion of the body. However, agreement is poor on the lower portion of the mid-section of the body. Comparison of the predicted surface flow patterns showed similar regions of separated flow. Predicted lift and drag coefficients were in fair agreement with each other.Mineck, Raymond E.Langley Research CenterUNSTRUCTURED GRIDS (MATHEMATICS); PRESSURE DISTRIBUTION; FLOW DISTRIBUTION; SEPARATED FLOW; PRESSURE RATIO; AERODYNAMIC DRAG; NAVIER-STOKES EQUATION; STRUCTURED GRIDS (MATHEMATICS); ROTORS; LIFT; ANGLE OF ATTACK; AERODYNAMIC COEFFICIENTS...

This book was released on 1994 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: A thin-layer Navier-Stokes code and a panel method code are used to predict the flow over a generic helicopter fuselage. The computational results are compared with pressure data at four experimental conditions. Both methods produce results that agree with the experimental pressure data. However, separation patterns and other viscous flow features from the Navier-Stokes code solution are shown that cannot be easily modeled with the panel method.
