Electronic safety insurance circuit applied to artificial rain rocket shell

Abstract

The invention provides an electronic safety insurance circuit applied to an artificial rain rocket shell. The electronic safety insurance circuit comprises a first-level ignition circuit, a second-level ignition circuit, a third-level ignition circuit and a breakage signal circuit; the electronic safety insurance circuit is characterized in that the first-level ignition circuit is composed of resistors R9, R10 and R11, a silicon-controllable rectifier Q1, a capacitor C4 and an igniting head F1, wherein the C4 is a detonation capacitor; the R11 is a large-resistance slow energy dissipation resistor; the second-level ignition circuit is composed of resistors R3, R4 and R8, a silicon-controllable rectifier Q2, a capacitor C2 and an igniting head F2, wherein the C2 is a detonation capacitor; the R8 is a large-resistance slow energy dissipation resistor; the third-level ignition circuit is composed of resistors R1, R2 and R7, a silicon-controlled rectifier Q3, a capacitor C1 and an ignitinghead F3, wherein the C1 is a detonation capacitor; the R7 is a large-resistance slow energy dissipation resistor; and the breakage signal circuit is composed of a MAX 4641 normally opened signal switch, a large-capacity energy storage capacitor C3, unidirectional current guide diodes IN4148 D1, D2 and D3, C5, C6 and R12. The electronic safety insurance circuit provided by the invention commendably realizes safe launching in action of the artificial rain rocket shell and is also low in cost, reliable, practical and feasible.

Description

technical field [0001] The invention belongs to the technical field of circuit safety insurance on rocket bombs, and in particular relates to an electronic safety insurance circuit used for human rain rockets. Background technique [0002] The Human Rain rocket has extremely strict requirements on the safe launch design, and its content includes two aspects: the safety of the launch platform system and the launch safety of the missile itself. Due to the constraints of cost, launching conditions, and the quality of operators, human rain rockets cannot be equipped with well-designed safety devices such as overload, off-frame, etc., and thermal detection like military rockets. The human rain rocket is divided into one-stage engine ignition, two-stage silver iodide catalyst ignition, and three-stage safety parachute throw parachute ignition. There is an inherent ignition failure probability in the first-stage engine ignition. When the engine fails to ignite, the second-stage and...
