Abstract

Ikan terbang merupakan salah satu jenis ikan yang mempunyai sirip yang dapat terbang melayang saat keluar dari air. Ikan terbang termasuk dalam kategori ikan tercepat di lautan, kemampuan ini tidak terlepas dari 2 pasang sirip ikan yang menyerupai sayap yang dimiliki oleh ikan terbang. Tujuan dari penelitian ini untuk mengetahui desain mekanisme buka tutup sirip meniru ikan terbang dan kinerja mekanisme buka tutup sayap tiruan pada purwarupa. Proses pembuatan desain menggunakan desain 3D pada perangkat software solidworks. Hasil desain dicetak menggunakan 3D printer yang memberikan hasil yang konsisten. Hasil pengamatan dari kedua purwarupa mendapatkan durasi pergerakan mekanisme yang berbeda. Hal ini terjadi dikarenakan penggunaan servo yang berbeda. Pada proses pengujian didapatkan hasil bahwa purwarupa model-1 mampu membuka sirip dengan kecepatan 0.190 detik dan menutup sirip dengan kecepatan 0.186 detik dengan sudut pergerakan sirip sebesar 80 deg. Purwarupa model-2 mampu membuka sirip dengan kecepatan 0.201 detik dan menutup sirip dengan kecepatan 0.196 detik dengan sudut pergerakan sirip sebesar 90 deg. Kesimpulan menujukan durasi yang dibutuhkan untuk melakukan gerakan membukan atau menutup sirip dibawah 0,3 detik. Saran yang dapat diberikan untuk penelitian selanjutnya agar lebih mengoptimalkan desain dan melakukan pengecekan secara berkala sehingga menghasilkan desain mekanisme ikan terbang yang sebenarnya.

Abstract

This study aims to know the cost of designing maintenance using the Reliability Centered Maintenance method. Engine and fuel control, is a fuel engine system and fuel control system; in charge of distributing and measuring fuel from the fuel storage tank, to the combustion chamber. Gas turbine or component area (Combustor), functions as a distributor of fuel used in aircraft systems and plays a role in carrying out its operation (Boeing 737-400 Aircraft Maintenance Manual). Reliability is the possibility of a component or system to be able to operate and/or carry out its functions. The function has been assigned to certain operating conditions and in a certain environment for a predetermined period of time. Thus, reliability is the probability that it will not fail or be able to perform its function for a period of time (t) or more. In the analysis of preventive maintenance financing, which is carried out when the reliability value reaches 70%, 60% and 50%, respectively, it is obtained for each component.

Abstract

In carrying out structured maintenance, a method is needed to increase the durability of an aircraft component, one of the methods used is the reliability method. The reliability of aircraft components is very necessary to ensure that each aircraft component is serviceable and runs according to its function in the aircraft system, so to increase the reliability of an aircraft component, the reliability method is very important to do. This study aims to determine the critical life time limit of the asset or system or equipment function and identify the failure mode that occurs in the Gas Turbine Engine component of the Boeing 737-500 aircraft because if this engine fails, it can result in flight delays and if not handled immediately can cause the aircraft to experience Aircraft on Ground (AOG) conditions, because it has the potential to disrupt airworthiness and threaten safety. This study uses exploratory research which aims to simplify problems to make them easier to solve. This study uses the Pareto diagram method to determine the highest type of failure in components, then analyzes it using the failure mode effect analysis (FMEA) method. Based on FMECA and FTA analysis, there are 3 failure modes, the failure modes include mechanical system (Bleed Valve), pneumatic system (Butterfly Shaft), electrical system (actuator). The failure was due to the occurrence of the top event part consumable, namely the bleed valve part with an RPN value of 192, followed by the butterfly shaft part with an RPN value of 75 and the Actuator part with an RPN value of 72. The pneumatic system and electrical system categories are prioritized to carry out preventive maintenance, which means it is a solution from industry players in an effort to maximize maintenance of the turbofan engine system accompanied by technical or economic analysis to ensure a system in extending the service life of parts in the aircraft system.
