BANDSLIP Advancements

Report No. ARL-TR-4943
Authors: Michael Minnicino
Date/Pages: September 2009; 18 pages
Abstract: A munition is said to be despun when the munition's angular velocity is significantly less than its band's angular velocity, thus the band slips on the munition and, hence, the name "slipband." With the emergence of smart munitions that possess advanced guidance for dynamic targeting capabilities, despun munitions are seen as the best approach for survivability of these finstabilized, canard-guided munitions due to the reduced aerodynamic loads on the fins and canards. The BANDSLIP code used for predicting the spin history of munitions has been improved. The most notable improvement is the capability to simulate projectiles shot through progressive twist gun tubes.
