Penggunaan float sangat menguntungkan karena tidak banyak merubah konfigurasi badan pesawat, namun massa dan desain float yang harus disesuaikan agar performa pesawat tidak berkurang. Impact antara air dan struktur float dapat menimbulkan beban kritis atau bahkan menyebabkan kerusakan struktur. Tujuan dari penelitian ini antara lain mengoptimisasi arah serat komposit dengan membandingkan empat susunan arah serat dengan melihat hasil kriteria kegagalan Tsai-Hill. Selain itu, simulasi metode elemen hingga dilakukan dalam kondisi simulasi statis untuk mengetahui respon struktur float dengan material Carbon-epoxy akibat pembebanan statik berdasarkan variasi beban pressure saat mendarat serta mengetahui pengaruh dari ketebalan komposit terhadap pressure distribution yang diterapkan pada permukaan bawah float. Dari analisis, didapat arah serat yang paling optimal adalah [0o2/45o2/-45o2/90o2]s dengan ketebalan komposit 2 mm. Perpindahan terbesar ada di bagian belakang float. Pada kondisi beban pressure saat VS0 tegangan yang diterima 202.422 MPa. Saat VREF tegangan yang diterima 352.927 MPa. Ketika kecepatan 70 Knot tegangan yang diterima semakin besar yakni 437.876 MPa dengan nilai Tsai-Hill 0.2622.

Goods transported to the cargo area can be a trigger for damage to the cargo area of the Airbus 330 aircraft, such as spilling fluid from the cargo packaging and the loading process or unloading cargo can cause corrosion in the cargo areaRoller track cargo compartment is one part of the aircraft that is susceptible to corrosion. In aircraft maintenance manual there is no step to apply coating application, where it is known that the coating is one of the protective coatings of a metal to overcome the attack from corrosion. The trial of coating application on the A330-200-200/300 roller track compartment roller track model was conducted for 1670 hours to determine the comparison of roller track corrosion rate values given the av15 adrox protective coating with roller tracks that were not given the av15 adrox protective coating. The test results obtained that the average value of corrosion rate of roller track models with coating coating layers is 0.1505 and without coating layer which is 0.4045 mmpy with coating usage efficiency of 62.7%. So it can be concluded that the application of coating on roller track cargo compartment is effective in inhibiting corrosion rate.

In this study, the type of aircraft used was the ATR 72-600 aircraft. One of the safety factors that need to be considered on aircraft is the landing gear system. The landing gear system regulates the wheel system on the aircraft for landing and also taking off. Given the importance of ensuring that the plane's wheels are securely locked or not, an up lock box system is needed on the landing gear. In the Up Lock Box system, it is not directly visible from the outside so that the working mechanism is not widely known. This study aims to determine the workings of the up lock box nose teaching aid system on the landing gear and to make a trial up lock box nose teaching aid on the landing gear. The research method begins with a literature study, then looks for design references, namely from the ATA 32 training manual. After that, make a design using the image of the up lock box from the ATR 72 aircraft, assemble the demonstran tool, calibrate and test the demonstran tool. The conclusions in this study are, how the up lock box teaching aids work in accordance with the up lock box working concept in the training manual, the results of the design and manufacture of props accompanied by modifications, as well as the test results on up lock box props in accordance with the up lock work concept box.

This research was conducted based on data obtained during testing at LAPAN (Lembaga Antariksa dan Penerbangan Nasional), where there was a case that became a concern. The test is about the free fall test, which results in a deflection that is considered too large. From these results it was decided to investigate further. This free fall test uses impact testing where a material is measured for its shock load resistance. Impact testing simulates the operating conditions of a material where the loading that occurs is not only in static conditions but also occurs in dynamic conditions. In the free fall test, a test was carried out to measure and see the resistance of the landing gear and crash box in receiving dynamic loads, when the aircraft landed. The main purpose of simulating this tool is for research and development of the free fall test equipment itself, as well as the design of the landing gear of the LSU (Lapan Survaillance UAV) drone in the future. The impact platform on the free fall test equipment plays an important role in impact testing, where the deformation of the plate holder will be converted by the load cell, into a signal received by the acquisition system. So it is designed to fit the existing needs. In this test equipment, the test object is given a load (50 kg and 200 kg), height (4.72 m and 1,204 m), so that it reaches a velocity (9,623 m/s and 4,861 m/s) with impactor crash box geometry and main landing gear as well as plate holder design based tools in the field. Based from testing, impact, and analysis using the finite element method in this study, it was found that the deflection value was 1.771 mm which reduced 94.61% for the crash box case and the deflection value was 2.696 mm with a reduction value of 87.85 % for the main landing gear case from the existing initial design. \u0000Keywords: Free fall test equipment, impact platform, landing gear, plate mount, main landing gear, crash box, finite element method, LSU.","PeriodicalId":354117,"journal":{"name":"Jurnal Teknologi Kedirgantaraan","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132615459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
