Jet interference on supercritical wings. Part I experiments on a two-dimensional wing. Part II experiments on a swept wing

Abstract

Wind tunnel tests have been made to investigate the influence of the jets from several different nozzles on the pressure distribution on adjacent wing panels with supercritical profiles. In Part I, an existing unswept wing panel was used for the tests; in Part II, a 25 ° swept wing panel was tested, and additional measurements were made with pylons fitted to two of the nozzles. The nozzle shapes and their location relative to the wing were chosen to represent a modern airbus configuration with fan engines. The results indicate that, in the cruise configuration, the influence of the jet is fairly small, and in most cases it simply reinforces certain features of the pressure distribution measured without jet blowing.
