Method for triggering electronic explosive time fuzes such that they are staggered in time

摘要

In order to trigger a plurality of electronic explosive time fuzes, which are jointly connected to a fuzing machine such that they are staggered in time, a signal flow, which is produced in each explosive fuze, for example a pulse sequence, is integrated by means of signals which are emitted from the fuzing machine in order to define the delay time, and is integrated up or down again or until equality of the integrals or of the initial values is reached, in order to implement the delay. According to the invention, the integration starts at the same time in all the explosive fuzes, the end of the integration being controlled by signals from the fuzing machine. This end and hence the time duration can be identical for all the explosive time fuzes, the relative differences between the delay times being determined by the ratio of the signal flows which are different during setting and when the delay is subsequently implemented, or the end points of the integration being different in a fuze-specific manner, while the two signal flows are preferably identical. In order to increase safety, a pulse sequence having a specific construction is emitted from the fuzing machine before the delay time is set, and is tested in each electronic explosive fuze, so that the setting of false delay values by interference signals is prevented. An energy store in each explosive fuze is not charged to a value which is sufficient for triggering the fuze until the test of the pulse sequence has been successful. <IMAGE>
