| ABSTRACT |
Purpose:
In this paper, storage lifetime of delay system in the fuse of 81MM illuminating projectile is estimated.
Methods:
Accelerated degradation testings of tungsten delay system using both temperature and humidity stresses were performed, and then delay time increase of the systems were analyzed as degradation data based on distribution-based degradation processes.
Results:
The estimated storage lifetime of detonator is between 11.8 years and 17.6 years with each stress-life relationship.
Conclusion:
Comparing with field data, storage lifetime of 90% reliability is about 12 years. |
