An evaluation is presented of the half-model test technique based on a systematic comparison of halfmodel test results with the corresponding full-model data. It is shown that the most important problems with this technique originate from half-model mounting and wall interference effects. At present, these effects can only be determined empirically using the full-model test results as a reference. It can then be shown that the pressure distribution on the wing and the off-design boundaries are well represented in the half-model tests. Finally, some typical applications of this technique, in which half-model test results are used on a relative basis, are presented.
