Abstract

Indonesia merupakan negara maritim, namun sebagian besar masyarakat Indonesia masih menggantungkan hidupnya pada sektor agraris. Sektor maritim perlu dikembangkan dan kendaraan laut sangat dibutuhkan sebagai fasilitas untuk mengembangkan sektor maritim. Pengembangan efisiensi kerja kapal bisa dilakukan dengan penambahan komponen hidrofoil yang dipasang pada lambung kapal Trimaran. Prinsip kerja dari hidrofoil yang terpasang pada lambung kapal Trimaran adalah hidrofoil yang memiliki sudut serang akan bergesekan dengan aliran sehingga menghasilkan gaya hambat kapal searah sumbu-X dan gaya angkat kapal searah sumbu-Y. Pada penulisan tugas akhir ini penulis menganalisa mengenai pengaruh sudut serang hidrofoil terhadap gaya angkat kapal Trimaran Hidrofoil. Sudut serang divariasikan sebesar 100, 200 dan 300 dengan Analisa menggunakan metode Computational Fluid Dynamics (CFD). Penelitian menghasilkan kesimpulan bahwa sudut serang terbaik berbeda-beda pada tiap kecepatan. Kecepatan 20 knot memiliki sudut serang hidrofoil terbaik sebesar 30 derajat. Kecepatan 30 knot memiliki sudut serang hidrofoil terbaik sebesar 20 derajat. Kecepatan 40 knot kapal sudah mencapai kondisi stall dimana kapal hidrofoil sudah kehilangan gaya angkat. ============================================================================================================== Indonesia is a maritime country, but the majority of Indonesian people are still dependent on agricultural sector. The maritime sector should be developed and sea vehicles is needed as the facility to develop the maritime sector. Development work efficiency can be done with the addition of ship components mounted on the hydrofoil trimaran hull. The working principle of the hydrofoil mounted on ship hulls is a hydrofoil trimaran which has the angle of attack will rub against the flow so as to produce a drag boat in the direction of the X-axis and lift the boat in the direction of Y-axis. In this thesis the author analyzes the influence the angle of attack of the foil Trimaran hydrofoil boat lift. Angle of attack was varied at 100, 200 and 300 with analysis using Computational Fluid Dynamics (CFD) method. The study concluded that the best angle of attack is different at each speed. Speed of 20 knots has the best angle of attack hydrofoil by 30 degrees. Speed of 30 knots has the best angle of attack hydrofoil by 20 degrees. Speed of 40 knots the boat has reached the stall condition in which a hydrofoil boat had lost lift.
