DTIC ADP010729: M219 Cavity Case

The data contained in this set consists of pressure tire histories measured on the ceiling of an empty rectangular cavity, and were measured as p&t of a joint BAe./DERA programme at the ARA wind tunnel at Bedford during November 1991 The overall programme consisted of several configurations, with bodies positioned at various proximities to the cavity, but the data presented here only considers the empty cavity, configured for both shallow and deep cases. Data were measured using Kulite transducers along the centreline of the rig, (which did not coincide with the centreline of the cavity itself). and, in an alterative configuration, on the centreline of the cavity. Measurements taken off the cavity centreline, but not included here, indicated that 3D effects were not significant.
