摘要
　　遙控水下無人載具（簡稱ROV）是目前水下技術發展的產物，其功能隨著科技進步而發展。在推進器方面，由於受限於尺寸的關係及推力需求的關係，傳統之船用螺槳並不再適用，因此有必要對其推進器葉片來設計，而環驅推進器則是新興發展之推進器。本文以ROV-TriggerFish的工作條件來設計水下載具之推進器，同時以系列螺槳及升力線理論方法進行。應用基因演算法於B系列螺槳做傳統式螺槳最佳化設計；另外以升力線程式(PLL)設計導罩及無轂環驅之螺槳，並予以比較及分析其性能。

ABSTRACT
　　Remotely Operated Vehicle(ROV) is a product of the development of underwater technique. On the part of the propulsor of ROV, there is a problem between the size of propulsor and the thrust required which result in smaller advanced coefficient than that of traditional marine propellers. It is necessary to design propellers for each ROV’s special condition. The rim-driven thruster is a newly developed propulsor. In this paper, the propulsor is designed by using B-series propeller optimized by genetic algorithm and by using proprlsor lifting line program(PLL). The design condition is according to the working condition of the ROV-Triggerfish. The results of the both designs will be compared with the original propulsor and their performance will be analyzed.
