Energy harvesting power sources for validating firing; determining the beginning of the free flight and validating booster firing and duration

摘要

A method is provided for validating a firing of a munition and duration of firing of the munition. The method including: providing the munition with a power supply having a piezoelectric material for generating power from a vibration induced by the munition; monitoring an output from the power supply; calculating an impact pulse from the output; and determining one or more of whether the munition has been fired and the duration of firing based on the calculation.
