| Outline of Final Research Achievements |
In this study, a free running scaled model test system for measuring unstable phenomena of planing craft, which include measurement devices, is developed (a radio control planing hull model: length: 1.0m, maximum forward speed: 12m/sec) to inspect safely and easily the occurrence of instabilities instead of a real-craft test. And, by using the system, the occurrence running condition, the characteristics of motion and the mechanism of occurrence of a spinout phenomenon* is investigated.
*A spinout is one of the more serious consequences of high speed maneuvering, in its moderate form, a spinout is the maneuvering motion that a hull suddenly begins spinning by small disturbance in high speed turning or straight running and rapidly stops without capsizing. In the serious cases, it may cause capsizing, hull damage and/or crew's injury.
