Abstract :
Many missions are so difficult to reach by humans, one of the interesting
parts to address is the agricultural sector, the rise of bird pests that interfere with
the agricultural process, and difficult to control agricultural land that has a large
area resulting in damage to agricultural products that have an impact on less
than the maximum farm results obtained. The use of bird-like UAVs is expected to
maximize the process of preventing damage to agricultural areas by flocks of
birds.
Modeling the internal structure of the aircraft is carried out using the
CATIA Software, modeling the structure grouped in parts by section, aiming to
make the analysis phase easier. In the analysis phase the results to be seen are
how the total deformation that occurs in the plane by assuming the load incurred,
and varying the analysis using load factor 2.5. after displaying the total
deformation, then displaying the stresses that occur, the voltage values that have
been obtained, will be used for the process of calculating the margin of safety.
The results of the UAV structure modeling show that the Fuselage
structure uses a semi monocoque structure, which uses bulkhed and Struktur as
reinforcement of the Fuselage structure. The wing is strengthened by 16 ribs and
uses carbon joiner s. And coated with skin using balsa material. In the tail only
uses polyfoam material as the main material. from the structure test shows that
the maximum stress that occurs in Fuselage is 0.055079 Mpa, the maximum stress
in the wing model is 11.541 Mpa. In the tail model the voltage occurs at 0.01159
MPa. With a total deformation of the tail of 0.0158 mm. total deformation in
Fuselage is 0.01363 mm. the total deformation of the wing is 1.7609 mm. these
results indicate that the structure used on the EAGLE-X aircraft is safe..
