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.

The dedicated
design team associated with the mechanical design directorate, stationed at the
REHS building, created the fire control radar component for the SIPER project.
The electronics section supplies an overview of the radar's electrical
component sizes, while the designs for cold plates and chassis are methodically
built using Siemens NX software, aligning precisely with these dimensions. In
the meantime, the thermal team investigates the coolant flow channels built
into the cold plate design. Simultaneously, the structural team conducts a
thorough structural analysis, carefully evaluating whether the proposed
parameters are met. When inconsistencies occur, the structural team gives
proactive advice for essential changes. This integrated and multifaceted plan
allows the successful development of the fire control radar component,
highlighting the project's commitment to precision and perfection.

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.
