Design, Fabrication and Control of Platform of an Electromagnetic Propulsion Device

Abstract

Electromagnetic propulsion devices have garnered significant interest as a promising technology for revolutionizing propulsion systems. However, these devices face limitations such as projectile accuracy, restricted firing angles, and thermal management challenges. To overcome these limitations, this project focused on the design of a versatile platform, implementation of an efficient thermal management system, and integration of advanced control systems. The designed platform facilitated the launch of projectiles in various directions and angles, enhancing versatility and accuracy. Through careful design and fabrication, the platform provided precise control and adjustability, enabling optimal projectile trajectories. The integration of specialized components, including Teflon material, mild steel shafts, and aluminum gears, ensured smooth and accurate movements of the platform. An efficient thermal management system was developed to mitigate temperature rise during launch. The system incorporated cooling mechanisms and appropriate coolant materials to dissipate the heat generated by high current flows. This effective thermal management ensured the durability and performance of the electromagnetic propulsion device. Distilled water was utilized as a coolant, and a radiator-like system facilitated rapid heat rejection, bringing the rails to ambient temperature within a short duration. Advanced control systems were implemented, utilizing the Arduino Mega microcontroller, to enable precise control over the platform. A numpad interface allowed users to input desired angles, which were translated into control signals for the NEMA 23 and NEMA 34 motors responsible for yaw and pitch adjustments, respectively. Real-time feedback on rotational angles was provided by an Inertial Measurement Unit (IMU), enabling accurate angle measurements displayed on a digital screen. Temperature sensors monitored coolant temperatures at the inlet and outlet, providing real-time temperature readings on the digital display.
