Abstract :
Structure repair is an aircraft maintenance activity specifically handling the structure of an aircraft that is damaged or damaged, so it is necessary to take action or treatment of the damage or damage in accordance with established procedures. The case that occurs in the engine inlet cowl is erosion found in the engine inlet cowl caused by foreign object damage (FOD) such as rocks rubbing against the lip surface of the engine inlet cowl. The influence of the engine inlet cowl that has erosion can change the aerodynamic flow leading to the engine blade. For this reason, it is necessary to simulate the strength of the Permanent Repair Rough Intake Lip Surface Structure on the Airbus 320 aircraft engine inlet cowl. Modeling and analysis are performed using CAD software and ANSYS based finite element method. After analysis with CAD and ANSYS software, engine inlet cowl lip surface modeling uses dimensions and sizes based on Manual Repair Structure and von misses stress values on engine inlet cowl lip surface modeling during damage and after repair is declared safe. The voltage value during damage with a normal landing load is 2.676 Mpa and the voltage value after repair is 2.5063 Mpa. The voltage value during damage with hard landing is 1.2045 Mpa and the voltage value after repair is 1.0887 Mpa and the highest margin of safety value on filler parts, this is because fillers produce the lowest maximum voltage compared to other parts. The lowest margin of safety is found in the structure when damage is because the structure when damage has a very high maximum voltage. The MS value of the engine structure after repair are more than > 0.
