As the majority of wind tunnel tests is related to aeronautics, most standard wind tunnel models resemble simplified forms of wings, airplanes or missiles. Such are, for static tests: NACA 0012 and CLARK Y (2D wing-segment models with typical airfoils), AGARD-B / AGARD-C (generic delta-wing -airplane shapes), ONERA -M (a generic transport-airplane shape), HB-2 (Hypervelocity ballistic model 2, a shape similar to a reentry-body). For dynamic tests, the often-used standard models are: SDM (Standard dynamic model, a generic fighter-like airplane shape somewhat similar to F-16)), BFM (Basic finner model, a generic conical-cylindrical missile with four fins at the rear end) and MBFM (Modified basic finner model). A number of other standard models exists as well.
