Abstract : Modern artillery projectiles often carry submunitions. The flight behavior of these submunitions once released from the projectile carrier are often poorly known. A program was conducted to measure the spin of an M42 anti-personnel grenade. A launcher system was assembled using a modified 4.2-inch mortar tube mounted to a 105mm howitzer carriage. A sabot/pusher and charge system were developed. An instrumentation and telemetry system was developed and three units were fabricated. Improper functioning of the howitzer/mortar firing mechanism produced delays in the firing sequence and batteries discharged prior to firing. Hence, no data were received. Subsequently, problems with the firing mechanism have been corrected. Additionally, rechargeable batteries have been procured and will allow for unusual test sequences or occurrences. New circuit devices and assembly procedures have also been established. These instrumentation procedures could be applied to most types of small bursting submunitions....
