Abstract

This research analyzes the provision of Equipment Storage Area (ESA) facilities to create a safe flow for Ground Support Equipment (GSE) at Sultan Aji Muhammad Sulaiman Sepinggan Balikpapan International Airport, given the increase in flight operations and the need for optimal ground handling. The main problems identified are the absence of clear markings in Storage B to indicate storage boundaries and the irregular layout of GSE. Using a qualitative descriptive method involving observation, interviews, and documentation in the airport's equipment storage area, the results indicate that Storage B does not meet operational safety standards due to the absence of markings, leading to unclear boundaries and disorganized GSE layout, which could hinder service delivery and reduce the safety and efficiency of GSE operations. As an improvement effort, it is strongly recommended to create clear storage markings in Storage B in accordance with the Director General of Civil Aviation Decision No. PR 21 of 2023, as well as to design a systematic GSE layout. This implementation aims to organize parking positions, improve land efficiency, prevent overlapping access routes, and ensure safer and more efficient ESA management in accordance with applicable regulations.

Abstract

Transonic buffet, triggered by shockwave–boundary layer interaction, produces oscillations that cause unsteady lift fluctuations, structural stresses, and accelerated fatigue damage. Understanding this chain—from shockwave to lift, stress, and fatigue—is critical for the durability of modern aircraft wings, especially those employing supercritical airfoils. This study investigates the SC(2)-0714 supercritical airfoil using CFD in ANSYS Fluent at Mach 0.8 with AoA 2°, 4°, and 6°, combined with structural and fatigue analysis in Abaqus and Fe-Safe. Results show stress levels between 1.26 and 12.6 MPa, well below the yield strength of Al 2024-T3, confirming safe static margins. However, fatigue life declined sharply with AoA, from 177,868 cycles at 2° to 130,282 cycles at 6°. These findings emphasize that while stresses remain within limits, transonic buffet–induced lift fluctuations critically reduce fatigue life, underscoring the urgency of incorporating buffet effects into structural durability assessments and airfoil design.
