变质心技术发展与应用

The moving mass technology uses the movement of the internal masses to change the position of the mass center of vehicles. It can avoid thermal ablation, rudder flutter, and high fuel consumption caused by traditional manners such as aerodynamic rudder and reaction control system. It is of high control efficiency and advantageous to maintain a good aerodynamic configuration for vehicles. Based on the connotation of moving mass control, this paper summarizes the characteristics of the two forms of moving mass configuration. The research progress of three moving mass control modes, including roll control, trim control and compound control, is sorted out. Finally, key problems faced by the moving mass technology, such as complex multi-body dynamics modeling, strong coupling and strong nonlinear control, design and development of high dynamic and high performance actuator, are discussed. By looking forward to the new scenarios of moving mass control application, the future research direction is pointed out.
