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.
