Abstract

LSU 03 Aircraft was used for LSU MISI with capability cruise up to 340 km. LSU 03 has an operation for marine safety from illegal fishing. To support the monitoring mission of illegal fishing with operation range up to 250 km or 3 hours flight, several required system are needed such as autopilot system, datalink, propulsion, and payload. All of system then analysed by an ELA (Electrical Load Assessment) of the aircraft system to know the necessary power required to conduct the initial mission of the aircraft. ELA analysis is done by calculating the power requirement from each component specification and function test of the component for validation of calculation result. From the results of the study, the amount of power consumption is 35% from the spec calculation, which is 32.43 Wh which can be accommodated by a battery system up to 4.2 hours. Whereas for ignition or aircraft engines whose source of battery uses LIPO 2S 7.4 Vdc batteries can accommodate the ignition energy requirements for more than 11 hours.

Abstract

This study aims to mitigate the impact of electromagnetic interference on the performance of electronic systems in Unmanned Aerial Vehicles (UAVs) by employing various shielding materials. The materials tested include carbon fiber, E-glass, E-glass with an aluminium foil, and E-glass with a copper foil. A Vector Network Analyzer (VNA) and scattering parameter (S-Parameter) analysis, including reflection, absorption, and multiple reflection, were used to evaluate the shielding effectiveness of these materials within the frequency range of 4 - 5 GHz. The results showed that E-glass coated with copper had good overall shielding performance for SER, SEA, and SET values. This material reached a SET value of 96 dB at a frequency of 4.6 GHz, followed by E-glass coated with aluminium. In addition, adding carbon layers increased the shielding effectiveness, while E-glass without coating had the lowest shielding performance compared to the other materials. These findings indicate that E-glass coated with metal provides superior shielding effectiveness compared to carbon fiber, even when used in greater thickness.
