F-5 Wing & F-5 Wing + TIP Store
Abstract
This data set relates to a transonic wind tunnel investigation carried out in l977 on an oscillating, slightly modified model of the outer part of a Northrop F-5 wing with and without an external store. The store represented an AlM-9J missile including its launcher. These tests were reported in references 1,2 and 3. The model proceeded from an F-5 wing model for subsonic tests by a slight reduction of the model span, needed to accommodate the tip Store considered in the document. In streamwise direction the wing possesses a modified NACA 65-A-004.8 airfoil, characterised by a droopnose, extending from the leading edge towards the point of maximum thickness at 40 per cent of the chord. The aim of the experiments was to determine the unsteady aerodynamic toads on a representative fighter type wing in the transonic and low supersonic speed regmies. Detailed steady and unsteady pressure distributions were measured over the wing, while on the store strain gauge balances obtained aerodynamic loads (Ref. 4). To study the effect of the external store on the unsteady wing loading (interference effects) as well as the unsteady loads on the store itself and its components. the model was tested in various stages of completeness. starting with the clean wing, successively more parts of the store (launcher, missile body, aft wings, canard fins) were added. Data presented here refer accordingly to the F-S clean wing configuration, growing in steps to the configuration of the F-S wing with complete tip store. The model geometry described in the Formulary concerns only the clean wing; geometry data concerning the tip store are not described in this document. However. they are presented in the figures and they are contained in the database on the CD-ROM, accompanying this chapter. simultaneously with these measurements also wind tunnel wall pressures were recorded to support wall interference effect studies.
