Abstract:

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.
