Yawing Motion of 5 in. MK 41 Projectile Studied by Means of Yaw Sondes

Abstract

The 5 inch MK 41 projectile was fired at both high and low muzzle velocities, and its oscillatory yawing motion studied by a telemetry technique. At high subsonic velocities this projectile develops a steady precessional motion of amplitude about 4 degrees. On a long flight, from high velocity launch, this behavior shows up late on the downward trajectory leg. The instability at small yaw and the limit cycle were found to be caused by a large and highly nonlinear Magnus moment. Aerodynamic coefficients were derived.
