Flight control device of artillery projectile which has a shock endurable and stackable structure of circuit plates

摘要

Disclosed are a flight control module of an artillery projectile formed by stacking and coupling unit cases where single-layer circuit boards of a shock-resistant structure are respectively seated and fixed, and a flight control device of an artillery projectile. A unit flight control unit enables the single-layer circuit boards to be endurable against the impact of a bombardment without being dented by the unit cases having a seating surface of an overall uniform surface supporting structure except a through space necessary for sockets and terminals, and may prevent a rebound effect after compression by requiring no molding material filling a stacking space between circuits. A control module with a plurality of control units stacked on top of each other and a control device to receive and fix the control module in a housing are arranged such that planar array positions of terminals cannot be overlapped with each other while being mounted on different positions between layers where the terminal and the socket are adjacent to each other in a process of repeatedly stacking the unit case having a flat cylindrical container shape and the disk type single-layer circuit board on top of each other. The terminals of all circuit boards stacked by this structure may not be removed or collapsed by being supported by a seating surface of a layer right below each terminal. This is applied even to the arrangement of processors to arrange the processors of the single-layer circuit boards not to be overlapped with each other in a stacking direction on the flight unit case adjacent to each processor, thereby contributing to weight distribution and heat distribution.
