基于伞控的再入体测控系统设计

Design of Re-entry Vehicle Measurement and Control System based on Parafoil

再入体测控系统是对航天器再入体伞控落区控制和回收电气系统的重要组成部分。提出了一种适应分离体再入的测控系统,实时采集再入体飞行参数,判定再入体飞行状态,根据既定的控制算法和飞行时序输出控制量,通过翼伞改变再入体飞行姿态和飞行轨迹,并将飞行参数和状态信息以无线方式发回地面。该系统由飞行信息传感器、飞行控制器、执行机构、外部设备等组成,具备完成再入体落区控制和回收的测控能力。

The reentry body control system is an important part of the reentry parachute control and recovery electrical system for spacecraft.A measurement and control system that is suitable for the separation of the reentry body is proposed.The system collects real-time flight parameters of the reentry body,determines the flight status of the reentry body,outputs control quantities according to established control algorithms and flight timing sequences,changes the flight attitude and trajectory of the reentry body through the wing parachute,and can wirelessly transmit flight parameters and status information back to the ground.The system consists of flight information sensors,flight controllers,actuators,external devices,etc.,and has the ability to complete the measurement and control of the reentry body landing area.
