We made a small model(Lpp=2.50m) of a medium-size bulk carrier(Lpp=150m) together with small twin podded propellers (D=0.080m) and a dynamometer to measure only the thrust of the podded propeller. In order to obtain the propulsive performance, we perform various experiments at Kyushu University, such as resistance test, P.O.T, propeller tests with dummy pod system/with real pod system(pusher and tractor types) and the load varying tests.From the obtained results, we analyse the propulsive performance by the combined uses of various results. In analysis, the pod and strut can be treated as appendages of the hull or parts of the propulsor. We show both results and discuss on the reasonable ness of the methods.On the other hand, we perform theoretical calculations corresponding to the above experiments to obtain the propulsive performance of the model ship by using a surface panel code which was developed at Kyushu university.By these approaches, we clarified the mechanism of the propulsive performance of the ship model with small twin podded propellers.

我们制作了一艘中型散货船（Lpp= 150 m）的小型模型（Lpp=2.50m），并配备了小型双吊舱螺旋桨（D=0.080m）和测力计，仅测量吊舱螺旋桨的推力。为了获得推进性能，我们在九州大学进行了阻力试验、P.O.T试验、使用虚拟吊舱系统/真实的吊舱系统（推进器型和牵引器型）的推进器试验以及负载变化试验等各种试验，并根据所得结果，综合利用各种结果分析了推进性能。在分析中，吊舱和支柱可以被视为船体的附件或推进器的一部分。同时，利用日本九州大学开发的面元程序对模型船的推进性能进行了相应的理论计算，阐明了小型双吊舱推进器模型船推进性能的机理。
