Abstract

Penggunaan sumber daya dan energi yang semakin banyak, mendorong munculnya beberapa penelitian tentang cara memaksimalakan energi tersebut untuk digunakan. Kebanyakan penggunaan sumber daya dan energi sampai saat ini banyak yang belum dimanfaatkan secara maksimal, hal inilah yang mendorong munculnya efisiensi energi. Penggunaan material carbon komposit, atau yang lebih dikenal dengan CRFP (Carbon Fiber Reinforced Plastic) banyak memiliki keunggulan dibandingkan dengan material besi paduan atau logam. Penggunaan material carbon komposit pada propeller diharapkan mampu meningkatkan performa dan kekuatan pada propeller. Penelitian ini menggunakan pendekatan interaksi struktur fluida, dengan metode analisis baling-baling dengan uji open water. Dilakukan serangkaian penelitian mengenai kekuatan propeller dengan mengacu pada desain Wageningen B-Series dengan material carbon fiber UD dan carbon fiber woven pada kondisi J=0,4 sampai dengan J=0,8, dan didapatkan nilai deformasi maksimum sebesar 35.55mm untuk carbon fiber UD dan deformasi maksimum sebesar 41.44mm untuk carbon fiber woven. Dari hasil deformasi ini, dilakukan analisa performa propeller dengan melihat perubahan pada performa propeller pada kondisi J=0,4 sampai dengan J=0,8. didapatkan peningkatan sebesar 7-19% untuk gaya thrust dan sebesar 8-24% untuk nilai torque dari propeller. Deformasi yang terukur menyebabkan peningkatan performa dari propeller dengan desain propeller yang sudah ada

The increasing use of resources and energy has encouraged the emergence of several studies on how to maximize this energy use. Most of the uses of resources and energy to date have not been utilized optimally, this is what drives the emergence of energy efficiency. The use of carbon composite material, or better known as CRFP (Carbon Fiber Reinforced Plastic) has many advantages compared to iron alloy or metal materials. The use of carbon composite material in the propeller is expected to increase the performance and strength of the propeller. This research uses a fluid structure interaction approach, with a propeller analysis method using an open water test. A series of studies were carried out regarding propeller strength with reference to the Wageningen B-Series design with UD carbon fiber and woven carbon fiber materials at conditions J=0.4 to J=0.8, and obtained a maximum deformation value of 35.55mm for UD carbon fiber. and maximum deformation of 41.44mm for carbon fiber woven. From the results of this deformation, an analysis of the propeller performance was carried out by looking at changes in propeller performance at conditions J=0.4 to J=0.8. An increase of 7-19% was obtained for the thrust force and 8-24% for the torque value of the propeller. The measured deformation causes an increase in the performance of the propeller with the existing propeller design
