| Abstract: | Using a basic structure model with a wrap-around fin （WAF） as a study case, the WAF＇s deployment duration when the structure model is rotating was investigated. The analytical solution expression and the numerical calculation method for the WAF＇s deployment duration were given. According to the feature of the configuration and loads of the structure model, a simple experiment on this structure model was developed and conducted successfully. The comparison between the experimental and theoretical results indicates that the calculation method for the WAF＇s deployment duration is effective. |
