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

Keselamatan penerbangan merupakan aspek krusial dalam sistem transportasi udara, termasuk pada operasional pesawat tanpa awak (Unmanned Aerial Vehicle/UAV) yang kini semakin luas digunakan di berbagai sektor. Salah satu ancaman serius terhadap keselamatan dan kelayakan operasional UAV adalah bird strike, yaitu tumbukan antara pesawat dan burung yang dapat menyebabkan kerusakan struktural signifikan, terutama pada bagian sayap. Sayap merupakan komponen kritis yang rentan terhadap dampak tumbukan karena posisinya yang terbuka dan luas. Penelitian ini bertujuan untuk menganalisis tingkat kerusakan pada struktur sayap pesawat UAV JATAYU-01 akibat bird strike, dengan memvariasikan jenis material skin serta kecepatan tumbukan. UAV JATAYU-01 dikategorikan sebagai small UAV, sehingga sangat rentan terhadap dampak langsung bird strike. Simulasi dilakukan menggunakan perangkat lunak Abaqus CAE untuk memperoleh nilai energi internal, tegangan (stress), dan regangan (displacement) yang terjadi pada struktur sayap. Konfigurasi struktur sayap terdiri dari core berbahan Styrofoam, low spar dan upper spar dari material komposit Carbon UD, serta skin yang divariasikan antara Balsa wood dan Styrofoam. Kecepatan tumbukan burung dalam simulasi divariasikan pada 20 m/s, 30 m/s, dan 40 m/s. Hasil simulasi menunjukkan bahwa pada kecepatan 40 m/s, skin berbahan Balsa wood menyerap energi sebesar 22,759 J dengan displacement 2,207 mm, sementara skin berbahan Styrofoam menyerap energi sebesar 29,271 J dengan displacement 9,494 mm. Temuan ini menunjukkan bahwa pemilihan material skin sangat berpengaruh terhadap daya tahan struktur UAV terhadap bird strike, dan menjadi pertimbangan penting dalam desain UAV yang aman dan andal dalam operasional di wilayah rawan burung.   Aviation safety is a critical aspect of air transportation systems, including the operation of Unmanned Aerial Vehicles (UAVs), which are increasingly utilized across various sectors. One of the major threats to UAV operational safety is bird strike—collisions between birds and aircraft—that can cause significant structural damage, particularly to the wings, which are vulnerable due to their exposed and broad surface. This study aims to analyze the structural damage to the wing of the UAV JATAYU-01 resulting from bird strikes by varying the skin material and impact velocity. The JATAYU-01 is classified as a small UAV, making it especially susceptible to such impacts. Simulations were conducted using Abaqus CAE software to evaluate internal energy, stress, and displacement values on the wing structure. The wing configuration includes a Styrofoam core, carbon UD composite for the low and upper spars, and skin made of either Balsa wood or Styrofoam. Bird impact velocities of 20 m/s, 30 m/s, and 40 m/s were tested. Results indicate that at 40 m/s, the Balsa wood skin absorbed 22.759 J of energy with a displacement of 2.207 mm, while the Styrofoam skin absorbed 29.271 J with a displacement of 9.494 mm. These findings highlight the significant influence of skin material selection on a UAV’s structural resistance to bird strikes and underscore its importance in designing UAVs capable of safe and reliable operation in bird-prone airspace

Abstract

Pesawat Tanpa Awak (Unmanned Aerial Vehicle atau UAV) adalah kendaraan udara yang beroperasi tanpa pilot, dan semakin banyak digunakan untuk berbagai misi sipil maupun militer. Pemilihan material UAV sangat penting karena memengaruhi performa struktural, efisiensi, dan keselamatan. Penelitian ini menganalisis pengaruh variasi material dan kecepatan tumbukan terhadap respons struktural fuselage UAV Ritewing Drak menggunakan metode elemen hingga. Tiga material diuji, yaitu kevlar, carbon fiber, dan fiber glass, dengan kecepatan tumbukan 4 m/s, 6 m/s, dan 8 m/s. Hasil simulasi menunjukkan bahwa kevlar memiliki nilai indeks kegagalan Tsai-Hill terendah sebesar 0,03411, lebih baik dibandingkan carbon fiber (0,03788) dan fiber glass (0,04121). Ketiga material menunjukkan deformasi plastik pada foam, namun masih dalam batas aman karena nilai Tsai-Hill tidak melebihi kriteria kegagalan. Peningkatan kecepatan menyebabkan peningkatan nilai Tsai-Hill dan deformasi: pada 4 m/s, 6 m/s, dan 8 m/s berturut-turut menghasilkan nilai Tsai-Hill sebesar 0,0211; 0,0261; dan 0,0341, serta nilai equivalent plastic strain pada foam sebesar 5,125; 10,29; dan 18,74. Simulasi membuktikan bahwa struktur UAV dengan material kevlar mampu memenuhi syarat kelaiktabrakan dan layak digunakan untuk aplikasi yang membutuhkan ketahanan benturan.   Unmanned Aerial Vehicles (UAVs), commonly known as drones, are aircraft that operate without an onboard pilot and are increasingly used in both civil and military applications. Material selection plays a critical role in UAV design, as it directly affects structural performance, energy efficiency, payload capacity, and operational safety. This study investigates the effect of material variation and impact velocity on the structural response of the Ritewing Drak UAV fuselage using the Finite Element Method (FEM). Three materials—kevlar, carbon fiber, and fiberglass—were evaluated under impact velocities of 4 m/s, 6 m/s, and 8 m/s. Simulation results indicate that kevlar exhibits the best crashworthiness performance, with the lowest Tsai-Hill failure index of 0.03411, compared to carbon fiber (0.03788) and fiberglass (0.04121). All materials experienced significant plastic deformation in the foam component, yet remained within acceptable limits, as their Tsai-Hill values did not exceed the critical failure threshold. Increasing impact velocity resulted in higher Tsai-Hill values and greater deformation: at 4 m/s, 6 m/s, and 8 m/s, the Tsai-Hill indices were 0.0211, 0.0261, and 0.0341 respectively, with equivalent plastic strain in the foam of 5.125, 10.29, and 18.74. These findings suggest that kevlar is the most suitable material for UAV fuselages in applications requiring high crashworthiness, as it provides superior structural integrity under impact conditions.

Abstract

This study aims to compare the structural performance of auxetic chiral and honeycomb sandwich panels under compression and impact loading to identify their potential application in lightweight aerospace structures. Numerical simulations were conducted using the ABAQUS platform to analyze the mechanical response and failure behavior of both core designs. A mesh convergence study was performed to ensure accurate and reliable simulation results. The impact tests were conducted at energy levels of 5 J, 10 J, and 20 J, while compression tests were applied with a displacement of 4 mm. The results show that the auxetic chiral core demonstrates superior performance compared to the honeycomb core by achieving smaller deformations and better energy absorption under equivalent impact forces. Furthermore, the auxetic chiral core exhibits a higher compressive strength of up to 111 MPa, outperforming the honeycomb core, which withstands only 50 MPa. Failure analysis also reveals that facesheets on auxetic panels experience significantly smaller damage areas compared to honeycomb panels. These findings indicate that auxetic chiral cores offer promising advantages for designing lightweight, impact-resistant aerospace structures.

Abstract

The development of Unmanned Aerial Vehicle (UAV) technology has advanced rapidly and is now applied in agriculture, mining, forestry, and the creative industry. Indonesia, with its vast territory and diverse topography, has great potential for UAV utilization. However, mastery of this technology at the vocational school level remains limited. SMK Angkasa 1 Jakarta, particularly in its aviation department, faces this challenge and requires strengthened competencies in UAVs. In response, Universitas Dirgantara Marsekal Suryadarma carried out a Community Service program as a form of technology and innovation transfer. The program aimed to enhance students’ conceptual understanding and basic skills related to UAVs, introduce prototype design processes, familiarize them with UAV system components, and provide learning modules and equipment for independent learning. The methods included the preparation of teaching modules, delivery of UAV materials (theory, conceptual design, electrical and navigation systems), hands-on practice in building polyfoam UAV prototypes, interactive discussions, and evaluations through pre-tests, post-tests, and questionnaires. The results showed a significant improvement in students’ knowledge, indicated by the increase in post-test scores and positive feedback on the training. The provision of UAV prototypes and modules further strengthened practice-based learning at the school. In conclusion, the training successfully improved students’ competencies while contributing to the quality of vocational education in aviation. Recommendations include establishing a UAV laboratory, continuous teacher training, broader collaboration with industry, and promoting student work through UAV competitions and exhibitions.
