ABSTRACT
UAV Cargo-X is designed with the mission of carrying cargo with a
maximum capacity of 2 kg, such as health equipment, especially for sending blood
to people in need quickly, besides it can reach places that are difficult to pass with
an estimated low cost. Categorized as fixed wing and requires a short runway to
take-off with tool called launcher. The Thrust of Cargo-X UAV launcher uses
pneumatics. For this reason, this study discusses the modelling, mechanism and
analysis of launcher structures.
The process begins by making the launch geometry concept and calculating
the launch force requirements of the launcher followed by the modeling process
using the CATIA V5 R21 software. Modeling that has been finished is imported into
ANSYS 15.0 software to perform analysis of launcher structure. There are four
simulations carried out in this study including: Simulation of the structure of
carriage position variations, collision simulation, cylinder pressure simulation and
cable pull simulation. All simulations carried out are to obtain maximum stress
values and maximum deformation as a basis for knowing the margin of safety value.
The modeling results of the UAV Cargo-X launcher have a rail length of 2
m, the launcher's total weight is 32,071 kg. The launching angle is 80. The power
needed for launch is 290501.37 Pa (2,855 Atm) with a force 588.8 N and can
produce a launch speed 15 m/s. Based on the results of all simulations on the
launching structure, the maximum stress is found in the cable pull simulation value
is 158.77 MPa. The maximum deformation is in the simulation value is 25%
carriage position variations value is 2.7032 mm. The lowest margin of safety is
obtained by cable pull simulation value is 0.354. The results of the overall
simulation concluded that all Cargo-X UAV launchers are still safe for operation.
