Introduction

Nerf N-Strike Elite Hail-Fire - First Look - 01.jpg

The purpose of this group project strives to give students the opportunity to work together as a group to increase their knowledge and provide a broader perspective on engineering decisions, utilizing the skills taught in the class. This project exposes students to basic project and group skills and examines group members critical thinking, engineering analysis, technical communication, and related areas of engineering. The product our group chose to analyze for this project was the Nerf-N-Strike Elite Hailfire. NERF is a toy brand created for young children that has been around since the 1970s. The Nerf-N-Strike Elite Hail-fire is from the family of NERF Blasters, one of NERF's most popular products. The Nerf-N-Strike Elite Hail Fire is a plastic toy gun whose function is to shoot foam darts at an opposing target in a fun, safe and child friendly environment.

Executive Summary

Throughout this semester we have dissected, analyzed, and reassembled a Nerf Hail-Fire Elite Blaster. This project has produced many findings throughout its various steps. Our product is toy gun produced by Nerf. The gun fires foam darts through the implementation of an electronic motor. The darts are pushed into the motor from the action of pulling the trigger. The electronic motor is powered by four AA batteries. This product implements the use of energy and mass transfers to accomplish its task of firing a dart. Through the dissection phase of this project we discovered how the mechanisms of the gun were connected. We found that by pulling the safety you are then allowed to pull the actual trigger to move the dart into the electronic motor assembly. Also, pulling the safety causes a switch to be pressed signaling the electronic motor to start up. We found that the magazine rack is rotated through the use of a spring and plastic rod connected to an exterior handle. Through the product analysis we found that the majority of components in the gun were made through the manufacturing process of injection molding. We also determined that the primary method of component connection throughout this product was through the use of screws. In completing the reassembly of the Nerf Hail-Fire Elite Blaster we were able to determine that this product in its original assembly was put together through the use of machines in an industrial assembly line setting. So throughout this project we have been able to determine a great deal of valuable information about this product and how it operates. These aspects are further outlined in more detail in each individual gate of the project.
