Experimental Magnus and Static Stability Characteristics of Ballistic Projectiles with Various Boattail Angles and Lengths at Mach Numbers from 0.5 Through 2.5

Abstract

An experimental investigation was conducted to determine the effect of boattail angle, boattail length, and base diameter on the Magnus-force and moment characteristics of spin-stabilized projectiles. The models were tested at Mach numbers from 0.5 through 1.3 over an angle-of-attack range from -2 to 8 deg. Data were obtained for a range of Reynolds numbers and for several spin parameter values. Results of this test, as well as results for Mach numbers 1.5, 2.0, and 2.5 from previous tests, are presented showing the effects of Mach number, angle of attack, spin rate, and boattail geometry.
