A safety and arming unit for a round of ammunition, comprising one or more acceleration sensors for detecting when the acceleration of the ammunition reaches at least two different predetermined linear acceleration values; timer means for measuring the time interval between the detection of two of the predetermined linear acceleration values, means for electronically comparing the said measured time interval with a range of predetermined and pre-set time intervals representing satisfactory firing for the round of ammunition, and means for producing an electronic signal when the said measured time interval falls within the range of predetermined and pre-set time intervals, which signal operates to arm the ammunition ready for detonation.
L'invention porte sur une unité de sécurité et d'armement pour munitions comportant un ou plusieurs accéléromètres détectant lorsque l'accélération atteint au moins deux valeurs prédéterminées d'accélération linéaire, un minuteur mesurant l'intervalle de temps entre les susdites valeurs, un comparateur électronique de l'intervalle de temps mesuré avec des intervalles de temps prédéterminés et préétablis correspondant à une mise à feu satisfaisante de la munition, et un moyen de production d'un signal électronique lors que ledit intervalle de temps mesuré tombe dans la plage des intervalles prédéterminés et préétablis, ledit signal armant la munition qui est alors prête pour la détonation.
