The Analysis of Electrical Power Used for the Upgraded Rocket and Missile Launcher

Abstract

The modernization of obsolete or non-operational military equipment serves as an efficient means to enhance the combat capabilities of the military. Specifically, upgrading the performance of long-serving multiple-launch rocket systems (MLRS) to support modern technologies is a cost-effective alternative to purchasing new systems. This study developed a model and assessed the electrical energy consumption of the firing control system in an upgraded MLRS, which is capable of automatic azimuth and elevation angle adjustment. The system's energy usage and accuracy were analyzed using a closed-loop control system powered by a PLC and servo motors, with position sensors for both azimuth and elevation. Data collected from simulated combat scenarios were used to calculate theoretical results and assess energy consumption during rocket firing operations. The results showed that the maximum power consumption of the motors for azimuth and elevation rotation is 400 watts, with an energy consumption of 12.3 watt-hours per aiming cycle. Given 15 to 20 aiming cycles per mission, the total energy demand would be approximately 250–300 watt-hours. The system can accurately control the positioning, which is sufficient for long-range salvo firing and can operate continuously throughout the mission.
