This fix helps avoid some grid generation issues and also helps to The adjustment made the angle slightly more pronounced where the curves meet,Īnd this corrected some very slight overlaps detected between these curves as they approached the corner. Were adjusted on the flap-bracket connections to the flap underside, and on the outer WUSS end-wall. (where a CAD face has a very cusp-like corner where two curves meet at nearly 0 degrees) The V2 geometry is different from V1 in the following way. Inboard/outboard flap angles of 43/40 deg:.Inboard/outboard flap angles of 37/34 deg:.Nominal Configuration (inboard/outboard flap angles on 40/37 deg):.The Test Cases for HLPW-4 are posted on the The second and third configurations have modified flap settings: one at 37/34 degrees, and the other at 43/40 degrees. The first is the nominal configuration, with inboard flap angle of 40 degrees and There are three landing configurations included. The geometry files are provided in both IGES and STEP formats. The following geometry files for this configuration are provided in full-scale inches. Which is slightly different than the geometry used to design and build the NASA 10%-scale model. (Note that flap angles, gaps, overlaps, and slat height / gap were changed on the test article in QinetiQįuture CRM-HL wind tunnel models going forward will be designed and built according to a reference configuration geometry specification, Semispan CRM-HL test article, as tested in the QinetiQ wind tunnel in 2019 Provided here represents the NASA 10%-scale Specifically, the particular geometry definition NASA High Lift Common Research Model (CRM-HL):Ī general description of the CRM-HL can be found in
