Distributing characteristics of the charge on the bomb-body with capacitance fuze

For establishing the equation of the capacitive target detection accurately, the distributing characteristics of the charges on the bomb-body with capacitance fuze were explored. Based on the Coulomb's law and the analytical discrete method of continuous charges, the dynamic equilibrium equations of the inducing charges on the bomb-body were set up. For the four cases of d0/L (the ratio between the electrode-distance and the bomb-length, the curves of the charge's distribution were given. It was concluded that: 1 the charge density decreases steadily from the end near the frontal electrode to the bomb tail, and the declining rate of the density is governed by d0 /L, the larger the value of d0/L, the higher the declining rate, and vice versa.
