Projectile Aerodynamic Jump Due to Lateral Impulsives

Abstract

The linear theory for spinning projectiles is extended to account for the application of a simple lateral square impulse activated during free flight. Analytical results are shown to produce simple contributions to the familiar aerodynamic jump formulation. Inquiries regarding jump smearing caused by nonzero impulse length are addressed and answered. The formulation shows for sufficiently long-range target interception; lateral impulse trajectory response for a guided projectile is independent of when the impulse is activated during the yaw cycle. Simple mathematical limits show the presented results reducing to those previously found for a zerospin projectile acted upon by a singular lateral impulse.
