Method for fuze-timing an ammunition unit, and fuze-timable ammunition unit

摘要

The invention is based on the concept of providing a digital data transmission of the fuze-timing data into a fuze-timable ammunition unit, for example with an HDB-3 (High-Density Bipolar) transmission code and voltage modulation. As is known from asynchronous data transmission, a start byte and a stop byte are respectively positioned in front of and behind the HDB-3 code, and are therefore components of thee fuze-timing data. The fuze-timing time is transmitted numerically as a data byte between the start and stop bytes.;Accordingly, the ammunition unit (3) includes fuze-timing electronics (4), which comprise a (voltage) demodulator (30), a (current) modulator (31) and a microprocessor (32) having an RC-oscillator cycle counter (32.1), an RC oscillator (33), a fuze-timing counter (34) and an actuator end stage (36). A firing sensor (35) serves as the fuze-timing-time triggering element at the start of the flight phase. Additionally, operating data of the oscillator (33) are corrected, so simple RC oscillators can be used.
