In aerospace vehicles, events causing relative movement of two or more objects, such as the separation of rocket boosters from a core rocket, often occur, and the study of avoiding collisions with objects is necessary. In such studies, as with wind tunnel tests, dynamic fluid-body interaction simulation has been used as one of major methods due to the advancement of the analysis technology and computer performance. In addition, the subjects of study have been complicated, and large-scale and unsteady interaction analysis is required. The Japan Aerospace Exploration Agency (hereinafter, JAXA) has taken the initiative in developing FaSTAR-Move, which is a tool for dynamic fluid-body interaction analysis, and Mitsubishi Heavy Industries, Ltd. (MHI) has cooperated in the development of the tool through joint research based on user needs and MHI's experiences in dynamic fluid-body interaction analysis. It has been verified that it is a highly practical tool in terms of analysis time and accuracy, and MHI has decided to operate the tool.
