"Some of the general purpose bombs in use by the Air Force andNavy (for example the MK80 and M117), are equipped with an air-driventurbine alternator (the FZU-48 produced by Alliant Techsystems).This air-driven turbine alternator has a double function:it provides the electric power to the fuze(s), and alsois used as a way to activate the fuze. The air turbineprovides power to the fuze only when the bomb is detached fromthe airplane (lanyard activation) and is traveling at a speed above agiven threshold. Nowadays, most general purpose bombs are equipped witha battery that supplies power to all the on-board electronics. Elimininating the air-driven turbine alternator will decrease thebomb drag, as well as reduce the cost, but will requirea new system to activate the fuze.The goal of this Phase I effort is to develop a low-cost, reliablefuze activation systems that relies only on pre-existing on-boardhardware, and to investigate, via simulation,the performance of such system. The fuze activation system willuse information provided by the bomb's navigation system(IMU and GPS) and otherexisting on-board information, including the lanyard and thenumber of GPS satellites in-view by the bomb.An Interacting Multiple Model (IMM) Kalman filter,will be used to detect the bomb's free-falling condition from otherdynamic situations, including aircraft maneuvers.The following tasks will be performed under the Phase I effort:1) Obtain dynamic m
