Abstract

Para nelayan harus menyesuaikan arah angin ketika mereka harus berlayar mencari ikan, siklus angin ini menjadi kenadala bagi para nelayan, mereka tidak dapat menentukan kapan mereka harus pergi berlayar, maka dari itu deperlukan desain layar yang mampu mengatasi masalah tersebut. Hal ini yang mendasari penulisan Tugas Akhir ini untuk mendapatkan desain konstruksi dan struktur layar yang baik. Desain layar menggunakan NACA 0015 pada bagian depan dan NACA 0009 pada bagian belakang. Sudut serang layar terhadap gaya sebesar 50 , 100 ,150 , 200 ,250 , 300 , 400 , 500 , 600 , 700, dan 900. Lalu simulasi di software 3D dan didapatkan hasil berupa Stress, Deformation, dan Factor of Safety pada masing-masing sudut serang. Dari hasil percobaan layar foil yang menggunakan NACA 0015 dan NACA 0009 didapatkan bahwa sudut serang 90o memiliki nilai strees, deformation terbesar dan nilai safety of factor yang kecil. NACA 0015 mempunyai nilai tegangan maksimal hingga 41.972,84 N/m2, nilai perubahan bentuk (deformation) maksimal hingga 1,207 mm, dan nilai safety of factor minimal 1.429e+005o. NACA 0009 mempunyai nilai tegangan maksimal hingga 49.180.144 N/m2, nilai perubahan bentuk (deformation) maksimal hingga 4,139 mm, dan nilai safety of factor minimal 1.220e+002 =============================================================================================== The fishermen have to adjust the direction of the wind when they had to sail for fishing, wind cycle is an obstacle for the fishermen, they can not determine when they need to go sailing, and therefore required the design of a sail that is able to resolve the issue. This underlying this final project to obtain construction and structural design of a good sail. Design sails using NACA 0015 at the front and at the back of the NACA 0009. Angle of attack display against a force of 5o, 10o, 15o, 20o, 25o, 30o, 40o, 50o, 60o, 70o, and 90o. Then in the 3D software simulation and the results obtained in the form of Stress, Deformation, and Factor of Safety on each angle of attack. From the experimental results using screen foil NACA 0015 and 0009 found that the attack angle 90o has a value strees, the greatest deformation and the value of safety of a small factor. NACA 0015 has a maximum rated stress of up to 41972.84 N/m2, the value of deformation up to a maximum of 1,207 mm, and the value of the minimum factor of safety of 1.429e + 005. NACA 0009 has a maximum stress value of up to 49,180,144 N / m2, the value of deformation up to a maximum of 4.139 mm, and the value of the minimum factor of safety of 1.220e + 002
