Abstract

AdjiE propeller merupakan sebuah inovasi baru dibidang screw propeller. Adapun hal yang membedakan tipe ini dengan screw propeller yang lain adalah adanya penambahan sirip pada bagian belakang (back) dari daun propeller. Dari hasil penelitian dengan percobaan langsung pada kapal nelayan tradisional, penambahan sirip ini mampu meningkatkan kecepatan servis kapal. Dengan menggunakan metode Computaional Fluid Dynamic (CFD) yang te/ah dikembangkan sejak tahun 1980, akan coba dianalisa pengaruh dari penambahan sirip tersebut terhadap rasio antara koefisien lift dan drag (C1/Co). Dari pemodelan Propeller AdjiE dan Propeller Original dengan metode CFD serta ana/isa data yang te/ah di/akukan, didapatkan ternyata propeller AdjiE mempunyai harga C1 28,76 per sen /ebih besar dari pada Propeller Original dan harga Cd 27,22 per sen lebih besar dari pada Propeller Original. Juga harga ratio C/Cd lebih besar sekitar 28,99 per sen dari pada Propeller Original.

AdjiE propeller is the new innovation in screw propeller field The differentiation of AdjiE propeller compared with another screw propeller is the additional offin on the backward of propeller blade. From the direct experimental results on fisherman boats is known that the additional of the fin can increase the speed of service. By using Computaional Fluid Dynamic (CFD) method that has been developing since 1980, the present computational experiment will try to investigate the effect of the additional fin on the ratio between the lift coefficient with the drag coefficient (Ct!Co). Computational experiment results show thats there is the increasing of lift coefficient, C1 value on AdjiE propeller about 28,76 per cent compared with original propeller and the drag coefficient, Cd increase about 27, 22 per cent compared with original propeller. The results of the ratio Ct!Co increase about 28, 99 per cent compared with original propeller.
