Surface Pressure Measurements on a Boattailed Projectile Shape at Transonic Speeds

Abstract

Measurements of wall static pressures on a model with and without a boattail are reported. The model shape is similar to that of M549 projectile geometry. Data were acquired at Mach numbers of 0.91, 0.94, 0.96, 0.98, 1.10, and 1.20; angles of attack of 0, 2, 4, 6, and 10 degrees; and circumferential positions around the model in 22.5 degree increments. Some of the pressure data were integrated over the model to provide axial force and static stability coefficients. Results are presented in both graphical and tabulated form and some comparisons are made with computational results.
