| 内容記述 | In order to clarify the ability, mechanism and problems for controlling the depth of a towed net using a canvas kite, a model test was carried out in a flume tank. The changes of the depth and attack angle of the model netting mouth, which depended on the pulling length of the lifting rope, were measured under two conditions, one in which a lifting rope was connected to a model kite (W/K) and another in which a lifting rope was directly connected to the top of the netting mouth (W/O) for purposes of comparison. The results obtained in this study were as follows. The depth decreased monotonously depending on the pulling length under the W/O condition, but it changed by decreasing or increasing under the W/K condition. The range of attack angle was from 15 to -10 degrees in the pulling length for the effective control of the W/K condition, while in the W/O condition, the attack angle of netting mouth decreased monotonously. The primary factor of the depth control using a kite seemed to be a direction of hydraulic forces by kite on the net mouth, and a relationship between the depth and angle of net mouth was shown, but there was a negligible influence on the projected area of netting mouth in the effective control. The effective ability and mechanism of depth control using a canvas kite were also discussed with the necessity of more basic data for the development and design of the depth control system. | |||||
