2. THE TEAM
Middle East Technical University and
Atılım University Design Build Fly (DBF)
is a student-run project in which
members develop, build, test and
optimize a custom radio-controlled
aircraft to compete in the international
DBF competition. The competition
sponsored by Cessna, Raytheon, and
the American Institute of Aeronautics
and Astronautics, enables students to
engage in the design process and to
produce an aircraft that meets the
requirements of a specified mission
profile.
The Team is a perfect place
where any interested student can come
and apply their practical engineering
knowledge to get the required solution.
That is how, in the team the senior
students are showing their technical
knowledge whatever they have learned
from their previous years in the
university to get themselves prepared
for the competition and for their careers
as well.

WE ARE A COMMUNITY.

5. The AIAA Design/Build/ Fly
competition challenges teams
to create a high performing
aircraft within a specified
mission profile. Held in
Wichita, Kansas the
competition is comprised of
both a technical report and a
flight performance evaluation.
The written component is
determined by evaluating the
team’s engineering
process for thoroughness,
justification and presentation.
The second component is the
mission score which
assesses a team’s aircraft
performance according to
competition rules. These rules
vary significantly each year
encouraging fresh designs
and new innovations.
Historically, the mission score
is calculated through a
formulation of 3 parts. The
first part is the rated aircraft
cost (RAC) which is
determined by physical
parameters such as weight
and wingspan. Second, is the
flight mission score which
generally evaluates the
aircraft on various flight
performance metrics such as
speed, handling capabilities,
and payload capacity. The
third part is typically a
wildcard and carries no
precedence. From judging an
aircraft on its ability to taxi
over rough terrain to its
capability of of carrying
another aircraft or a bottle
inside the third aspect is often
the defining characteristic of
the competition.

1.Conceptual
Phase
Early stage direction is
vital for efficient use of
time and resources
throughout the year.
Immediately following the
release of the rules, we
began to dissect the
needs and requirements
of the competition. This is
done through
computational scoring
analyses with Matlab and
numerous trade studies. It
is upon this understanding
of the competition where
initial concepts and ideas
are conceived.
3.Detailed Design
The output of detailed design is a functional
aerial platform representative of initial sizing.
Aerodynamically, the airfoil and wing geometry
is determined with the aid of XFLR5. The
propulsion system, landing gear, and fuselage
are refined from an array of trade studies. And
the empennage and control surfaces are sized
through internally developed MATLAB code. The
entire assembly is then modeled in
SOLIDWORKS with attention to
manufacturability. Additional refinement takes
place in the later stages of detailed design,
including drag minimization using FLUENT and
structural optimization with ANSYS.

7. While a great deal is
predicted through design,
the greatest insight
comes from prototyping
and testing. Our
prototypes are built from
a wide range of materials
such as: balsa, various
foams, carbon fiber,
Kevlar, and Garolite. This
spectrum necessitates
the use of various tools,
which include but are not
limited to: laser cutters,
foam cutters, CNCs.
Additionally, some
aspects of the design are
evaluated on a
subcomponent level. This
includes propeller, motor,
and battery performance
benchmarking as well as
material and
manufacturability
evaluation for structural
components. We are
always seeking new
materials and
manufacturing processes
to improve our aircraft.
4.Prototyping
5. Validation
and Iteration
Upon completion of each
prototype, the aircraft is
evaluated for its
performance. We run
each mission of the
competition while pulling
flight data through
various onboard
telemetry such as
altimeters,
accelerometers, pitot
tubes, and tachometers.
This flight data, in
addition to knowledge
gained from previous
steps, allows us to hone
in on areas of
improvement for the next
pro- totype. We believe
this to be the most
effective way of creating
a winning aircraft and will
iterate from detailed
design to validation a
minimum of 3 times.
BY INTEGRATING TRADITIONAL
ENGINEERING ANALYSES WITH NOVEL
MATERIALS, MANUFACTURING
METHODS, AND DESIGN FEATURES,
WE PUSH THE BOUNDARIES OF
FLIGHT.
