Supersonic Wind Tunnel Tests of the Three-Stage Target Missile Arpat

摘要

Wind tunnel tests were performed on a four-percent scale model of the ARPAT Target Vehicle in the Ballistic Research Laboratories' Supersonic Wind Tunnels at Aberdeen Proving Ground, Maryland. Fins of varying area and deflection were tested at Mach numbers of 2.00, 2.50, 3.00 and 4.50. The dynamic roll rate, the pitching moment coefficient, the normal and drag force coefficients, and the center of pressure positions were determined through an angle of attack range. The results are presented and summarized in this report. (Author)
