Abstract

PUNA Pasopati, the wing is an important part to generate lift. However, the magnitude of the lift force must be able to be resisted by the wing structure. Therefore, the purpose of this study is to determine the most optimal material and thickness of the spar structure, ribs, and front reinformence leading edge on the PUNA Pasopati wing. This research conducted static tests on the wing structure with skin construction, front reinforcement leading edge, ribs, and spars using the finite element method. static tests were conducted with material and thickness variations on the spar, ribs, and front reinforcement leading edge structures. In material variations, carbon fiber reinforced plastic is stronger than plywood. Displacement on the wing with carbon fiber reinforced plastic material is 61.03% smaller than plywood, but the wing with plywood material weighs 68.43% lighter than carbon fiber reinforced plastic. However, the plywood material gets a safety factor value of 1.15 which means below the limit of the safety factor value of 1.5. Thus, the wing with carbon fiber reinforced plastic material for PUNA Pasopati is more optimal than plywood. The higher the thickness of the ribs, spar, front reinforcement leading edge structure, the smaller the displacement and stress on the wing. Although the 1 mm thickness has the highest displacement and stress values, it still has a safety factor value above the limit. Thus, a thickness of 1 mm is the most optimal.

Abstract

Bird strikes are a threat that affects the structural integrity of aircraft, and unmanned aerial vehicles (UAVs) are no exception. Bird strikes cause changes to the shape of the wing, including the airfoil, which affects the aerodynamic performance and flight safety of the aircraft. Manufacturers must conduct various tests before a UAV is authorized for commercial use, one of which is structural strength. Numerical simulation of bird strikes is an important part of UAV component design to reduce testing costs. This study aims to analyze the structural response and aerodynamic performance of the UAV airfoil caused by bird strikes. The deformed wing geometry for computational fluid dynamics analysis was obtained from bird strike simulations using the finite element method and the smoothed particle hydrodynamics bird model. The deformed wing geometry is analyzed using the computational fluid dynamic software to obtain the pressure distribution around the airfoil, pressure coefficient, lift, and drag. The results show that the deformed airfoil's leading edge alone experiences positive high pressure. With a change in angle of attack, the deformed wing's lift coefficient is lower than the undeformed wing's. In contrast to the lift coefficient, with a change in angle of attack, the deformed wing's drag coefficient is higher than the undeformed wing's because the pressure distribution is disrupted.

Abstract

The use of UAV (Unmanned Aerial Vehicle) by government and private institutions has been widely practiced. One is for monitoring needs, mapping an area to another, and more specific military needs. UAV carry a variety of sophisticated electronic equipment, and landing gear must be capable of supporting the load. Absorbing impact energy is essential to prevent damage to the equipment. The landing gear drop test simulates the stiffness of the landing gear to receive an impact load when the aircraft lands. The primary purpose of the tool's design is to facilitate the effective and efficient research and development of landing gear design in the future. This study's landing gear drop weight test was designed for all types of LSU unmanned aircraft (Lapan Surveillance UAV). Landing gear drop weight is designed with several systems to support the ability to determine the speed before the impact, impact force, and deformation on the landing gear strut as a parameter for future landing gear research. This test tool utilizes gravity as an impact propulsion. The test equipment design refers to the CASR 23 standard test. This study compared the test equipment design solutions and the construction deflection analysis to ensure the design results could be made. The bending value of the hoist plate on the rig design that has been made is 57.7 MPa. The value of critical buckling in the rig column is 28,353 kN.
