Abstract:

This study analyzed the torque on the sector gear of the Mk 42 Mod 3 Rear Fitting Safety Device RFSD used in variable time VT fuzes for Navy gun ammunition. The study was initiated following two proposals by the production contractor to modify the sector gear to produce increased torque and improve its reliability when used in 5-in .38 caliber gun ammunition. The study concluded that one of the proposals was unsound and the other was feasible with a little fine tuning and further analysis.
