| Abstract: |
| Objective To research the heat stability of multi-point array EFI charge. Methods The slow cook-off tests of HNS multi-point array charge according to four different sizes, φ3 mm×3 mm,φ4 mm×4 mm,φ5 mm×5 mm,φ4 mm×8 mm, were carried out. The response characteristics of HNS multi-point array charge in three different heating rates—3.3 ℃/h, 5, 10 ℃/min—were obtained. Results The test responses had an increasing trend with the improvement of heating rate under the same charge condition. The test responses have an increasing trend with the improvement of charge at the same heating rate condition. Conclusion Array charge is benefit to dispersing the heat accumulation of HNS charge, reducing the response strength in the cook-off test, and increasing the thermal safety of charge. |
