1.   Introduction

The primary aim of the summer internship, ME 400, was to strengthen and develop the theoretical and practical knowledge obtained in prior mechanical engineering semesters. This program aim to provide students with  knowledge of the management connections that bridge the gap between technical departments and non-engineering sectors. During my ME 400 Summer Practice, I had the honor of interning at Aselsan Inc., located in Gölbası. My specific work involved contributing to the design and structural analysis departments of the Mechanical Design Unit. The thorough education I got in CAD and Manufacturing Technologies. Armed with this information, I embarked on my internship experience, ready to put theory into practice and bridge the gap between academia and industry. During the internship, I went on a journey of learning and growth that allowed me to combine theoretical principles with actual implementations. My tasks included observing CAD designs for various market sample products. These designs were crucial in assisting engineers in determining the viability of manufacturing these devices. Furthermore, I was tasked with carefully detailing the production methods for an existing part using CAD software, which provided great insights into the complexities of real-world engineering processes. Aside from the technical parts of my internship, I got the rare chance to immerse myself in Aselsan Inc.'s varied operations. The company's organizational structure revealed a tapestry of complications that played an important part in its operations, with its five unique campuses acting as independent entities. Seeing how engineers used the same academic principles and relationships from our courses while utilizing cutting-edge computer tools for fast problem-solving fostered a deep appreciation for the integration of technology and innovation in modern engineering methods. Furthermore, my exploration of other facilities, particularly in the domain of electronics, increased my awareness of other systems and processes. The exposure to diverse aspects of engineering cemented my interest for the discipline and deepened my understanding of the vital role that multiple departments play in synergy. Throughout this report, I will go into detail about Aselsan Inc., including its illustrious industry reputation, the various locations and divisions that contribute to its success, and insights into the production and analysis techniques and management information systems that power the organization's efficiency. Summer internship at Aselsan Inc. has been a transformative phase that has enriched my academic journey.

7.   Explanation of Your Contribution to one of the Projects

A detailed explanation of the contribution of the student to one of the projects during the summer practice (Scope and description of your assigned task, literature survey, detailed calculations and technical drawings)

During my internship, I worked in the Mechanical Design Department's Structural Analysis Team, where I was tasked with determining the proper fasteners for the radar chassis utilized in the Gökkubbe project. I was in charge of giving a bolt presentation, explaining the fundamental concepts of bolt mechanics, and presenting the VDI 2230 catalog.

My goal in giving this information was to help design engineers make more informed bolt selection selections and to aid structural engineers in precisely modeling the chosen bolts. In addition, I will be participating in the setup of a test instrument and, if necessary, the calibration of the Ansys program.

This project is critical to the effective deployment of the Gökkubbe radar system. Proper bolt selection is critical for ensuring the structural integrity and stability of the radar chassis under a variety of operational scenarios, including as high-speed movements and external loads. I hoped to educate the staff with industry standards and rules by presenting the VDI 2230 catalog, which will allow for more efficient and successful bolt selection operations.

Furthermore, my participation in the setup of a test apparatus and the calibration of the Ansys program will give the team with useful data and insights into the bolt performance. This will allow us to model and analyze the bolts' behavior under various stress scenarios, ensuring that they match the project's stringent safety and performance criteria.

In summary, my role in the Structural analysis team during my internship was critical to the success of the Gökkubbe project. I hope that my efforts will provide the design and structural engineering teams with the knowledge and tools they need to make informed decisions and build a robust and reliable radar chassis for this crucial defense project.
