Description

Technical Field

[0001] This utility model relates to a ballistic environment acquisition mechanism. Background Technology

[0002] The ballistic environment acquisition mechanism is crucial for fuze design. As a key component of the ammunition system, the performance of the fuze is closely linked to the ballistic environment. Different ballistic phases exhibit varying environmental characteristics, such as overload during launch, attitude changes during flight, and electromagnetic and shock environments near the target. Existing ballistic environment acquisition mechanisms suffer from weak structural strength and are unable to adapt to environmental changes during flight in terms of timing and detonation control. They fail to accurately sense the environment near the target and detonate in a timely manner, thus affecting the reliability, safety, and combat effectiveness of the fuze. Utility Model Content
