Anti-static Design and Performance Verification of the Bridge Wire Explosive Bolts

Objective To design a kind of bridge wire explosive bolts with anti-static structure. Methods Using the combined method of "discharge" and "wall", bridge wire explosive bolts with structure of needle-shell of electrostatic air was designed, and various performance verification was conducted. Results The bridge wire explosive bolts designed passed the original rational test of the overall structure, static discharge test, the separation speed verification experiment, functional margin test, structure strength margin test, system test, and the validation of identification test. Conclusion Bridge wire explosive bolts could not only solve the unsafe factors of anti-static, but also realize reliable separation function, and had good application prospect in practice.
