F35C Joint Strike Fighter Additive Manufacturing Tailhook Redesign
F35C Joint Strike Fighter Additive Manufacturing Tailhook Redesign 4/24/16 Submitted to Lockheed Martin Representative Team EDSGN 100, Section: 23 Group 4: Kiran Judd, James Harris, Madeline Woody, and Zach Ceneviva Abstract: The objective for the project was to design, prototype, and manufacture an effective redesign of the Lockheed Martin F35C tailhook, utilizing additive manufacturing. The F35C tailhook, like many other subtractive manufactured parts, suffers from a waste of excess material and limitations when creating advanced designs. The main question relating to the current process is how does one eliminate the total amount of material used, while still retaining the original strength? For this reason, when designing the prototype material reduction, affordability, accessibility in the field, effectiveness, and durability were treated with the utmost importance with respect to design criteria. After the printing of the prototype, it was necessary to test the design criteria in order to see if the efficiency and reliability met the desired goals for the tailhook. The tailhook prototype did not pass all of the set criteria for its design, but performed especially well when compared to the set criteria for the durability. Although the initial prototype performed well during the durability test, it did not perform as well as hoped within the material reduction, affordability, and effectiveness categories. These areas proved to be lacking, leading to corrections which would later lead to the improved second prototype, created by the team. Following the improvements implemented within the second prototype, an effective, durable tailhook was created utilizing additive manufacturing processes. Table of Contents Introduction Pg.
