高速艦艇已成為現今船舶的發展趨勢，有關高速艦艇的船模實驗，過去受限於拖航水槽性能與台車速度影響，以致相關實驗技術受到限制，大多實驗需仰賴國外商業水槽進行相關研究，經由本研究有助於提升拖航水槽進行噴水推進高速艦艇船模實驗。本研究主要目標是噴水推進船模自推實驗技術建立以及統整相關理論，參照國際拖航水槽協會ITTC實驗指南與國內外各式文獻，會設定不同實驗條件，分別於同一船模安裝單噴水推進器與雙噴水推進器，探討2種不同噴水推進器佈置對於實驗技術建立的影響。首先會於迴流水槽進行測試，初步了解噴水推進與馬達的性能狀況，再經由阻力實驗獲得船模在不同實驗條件下的阻力變化與其他資訊，自推實驗依照2種不同實驗條件進行，經由實驗結果推估船模的自推點、量測出轉速(n)、推力(T)、轉矩(Q)、拖曳力(Fd)及航行姿態(sinkage & trim)，再經由動量通量法可推估總推力(Tg)、淨推力(Tnet)、流量(QJ)、推減係數(t)、理想噴流效率(ηI)、傳遞功率(PD)與整體效率(ηOA)。次要目標探討在現有船模加工後進行實驗的可行性。本研究亦發現噴水推進船模在設計上會因幾何空間受限，影響儀器配置，特別是測量流速或壓力。

High Speed Marine Vehicles(HSMV) have become the development trend now. In the past, the ship model experiments on high-speed vessels were limited by the performance of the towing tank and tow speed, most of the experiments relied on foreign towing tank, so that the experimental technology was limited. This research will help to upgrade towing tank ship model experiments for high-speed water jet propulsion test. The main objective of this research is to establish the self-propulsion experiment technology of the water jet propulsion test and integrate the theories. The experiment followed International Towing Tank Conference (ITTC) waterjet propulsion guidelines and some previous research. Under different experimental conditions, and installed single and double waterjet propulsors in the same model, studied the influence on the establishment of experimental technology. First, experiment was tested in the circulating tank to obtain a preliminary performance of the waterjet propulsor and motor performance, and then through the resistance test to obtain the resistance value and other information of the model ship in a towing tank. The self-propulsion experiment was carried out according to different waterjet propulsion arrangements. The results include rotational speed (n), thrust (T), torque (Q), and tow force (Fd) of the ship model and montion attitude (sinkage & trim), and estimated the self-propulsion point. Then, the momentum flux is used to method to obtain estimated gross thrust (Tg), net thrust (Tnet), flow rate (QJ), thrust deduction coefficient (t), ideal efficiency(ηI), deliver power(PD) and overall efficiency(ηOA). The secondary objective is to evaluate the feasibility on existing ship model processing. This study also found that we need to pay attention on geometric space arrangements, necessary due to the instrument configuration, especially the measurement of flow velocity or pressure.
