Executive Summary Experimental Setup
Background
● A railgun is an electromagnetic accelerator that launches metallic projectiles using electromagnetic force
● The ideas of electromagnetic forces are implemented when building an autoloader for the railgun
● Autoloaders allow for continuous projectiles to be fired without loss of speed and consistency
● Our autoloader has two parts, a loading mechanism and the magazine
● Everything will be controlled by the ATMEGA2560 microcontroller
● The microcontroller we will be using will be the slave and it will be talking to the master microcontroller inside of the handheld box.
• Force Test being applied on pusher arm/linear actuator. Six batteries = 390 lbs • We need up to 40 lbs of force to load depending on the clamping force.• Functional LCD display and Continuity check• Basic circuit prototype with PCB Autoloader design

Conclusions
• Autoloaders eliminate human interaction by not having someone there to load the projectile into the gun
• In comparison to the previous autoloader made by a team, we have shortened it by 4 inches in length
• Autoloaders reliably load anything into the chamber at a faster pace as well as them being safer than a human loading something in a chamber
• Purpose of an autoloader is to eliminate the human element and automating a repetitive task that could be done more efficiently and safer

● AutoCAD exploded diagram of the autoloader as well as the magazine this setup is an early mock of the autoloader as well as the railgun and its inner workings
● The projectile we will be firing from the railgun
● Auto or Self-loading firearms use a mechanical action to capture energy from a previous projectile’s propellent to load the next projectile without any user input
● This allows for a high rate of fire and can be used for a variety of different sized calibers and ammunition types
● This methods not applicable due to a railgun’s method of propulsion. This results in a human loader having to load each projectile By hand and thus a lower rate of fire compared to a conventional firearm
● To counteract this issue an autoloader must be implemented to remove the need for slow hand loading
• Voltage Regulator to 12 and 5 Volts from 48 Volts• Continuity Check is controlled by the microcontroller• Microcontroller checks to see if the gun is loaded or unloaded via continuity check
system.• Loading starts the linear actuator and pushes the projectile into the gun then pulls
back to its original position• After loaded completes and is charged, the gun may fire using the hand held
controller.• Tests revealed that 800N or 330l lbs of force was needed to properly • We decided to go with the ATmega2560 board, Relay Board, and the Linear
Actuator because it fits in the requirements of 5-12 Volt range with 3 Amps across all three devices merged with a PCB Design created by us using EagleCAD. This will work seamlessly together.Single Pull Double Throw Relay (DZS

● 120V AC comes from the wall into the switch on the handheld.
● This is then pushed into the 15V/5V DC regulators that correspond with the power supply/handheld controller
● The autoloader team will tap into the handheld switch and feed the 120 V AC to our 8V/5V DC regulators which will then be pushed to the linear actuator/AtMEGA
