Abstract
Supersonic wind tunnel tests series were made in the DREV 0.6 m x 0.6 m indraft facility in contribution to a cooperative research work between DREV and DRES to study the flight dynamic stability of a particular explosively formed pojrectile configuration named "BLUNT BODY". These tests were intended to get experimental data on surface static pressure distribution and aerodynamic stability coefficients. This memorandum describes wind tunnel tests made with a 6 blunt fin EFP model. The model configuration was obtained from high speed photography of various real EFP in flight. A total of 107 runs were made at Mach numbers of 2.97, 3.50 and 3.99, for a variety of roll angles and angles of attack up to 15 deg. Equations used for treatment of data are presented together with test conditions and a summary of results. Also, a description of instrumentation test setting and several model drawings were incorporated. Wind tunnel results compared well with DREV CFD simulations.
