中文摘要: 针对大尺度柔性平流层飞艇在流固耦合效应下飞艇变形与飞行动力学耦合的问题,综合考虑几何非线性大位移变形、外部载荷-柔性变形-动力学耦合等因素,揭示飞艇变形与阻力/升力/力矩/气动导数等动力学的耦合影响规律。研究成果为平流层飞艇动力学建模与定点保持控制设计提供理论基础。

英文摘要: The large scale flexible stratospheric airship experiences large deformation in station-keeping subject to fluid-structure interaction, which produces effects on aerodynamics, and vice versa. The coupling law between airship deformation and its dynamics is revealed based on the investigation of large displacement of geometry, the interaction of loading-deformation-dynamics. The research results can establish the technique base for dynamics modeling and station-keeping control of stratospheric airship platform.
