| 中文摘要: |
| 目的 针对低功耗换能元点火能力不足的问题，采用油墨直写技术制备一种油墨含能NiCr桥换能元。方法 以Al/CuO为主体含能材料，完成含能油墨的制备，并将其集成到NiCr桥上，形成油墨含能NiCr桥。对油墨含能NiCr桥换能元进行电爆实验和间隙点火实验，验证油墨含能NiCr桥的非接触式点火能力。结果 在24 V/100 µF条件下，油墨装药量为2.9 mg时，油墨含能NiCr桥可以在5 mm间隙下点燃B/KNO3装药，在间隙为1 mm条件下，油墨含能NiCr桥能够成功引发装药为硝酸肼镍的雷管。结论 含能油墨的引入能够增强NiCr桥的点火起爆能力，有望在工程实践中进行应用。 |

| The work aims to prepare an energetic ink NiCr bridge igniter by ink direct writing technology to solve the problem of insufficient ignition ability of low energy igniter. Energetic ink was fabricated with Al/CuO nanothermite as the main energetic material, and then integrated on the NiCr bridge to fabricate the energetic ink NiCr bridge igniter. Electro-explosion experiment and gap ignition experiment were carried out on the energetic ink NiCr bridge igniter to verify the non-contact ignition ability of energetic ink NiCr bridge. The energetic ink NiCr bridge igniter could ignite the B/KNO3 charge at a gap of 5 mm under the condition of 24 V/100 µF and ink charging amount of 2.9 mg. At a gap of 1 mm, the energetic ink NiCr bridge igniter could successfully initiate a detonator charged with nickel hydrazine nitrate. The introduction of energetic ink can enhance the ignition and detonation ability of NiCr bridge, which is expected to be applied in engineering practice. |
