The present disclosure describes an autonomous flight safety system (AFSS) that incorporates an autonomous flight termination unit (AFTU) that enables AFSS monitoring of various termination conditions for activating a flight termination system (e.g., in the event that a termination condition is detected). Such termination conditions include boundary limit detection (e.g., whether the vehicle location is outside the planned flight envelope or is planned outside the planned flight envelope), and rocket instability detection (e.g., whether the pitch rate and yaw rate exceed a certain threshold indicative of vehicle instability). For example, the AFTU may incorporate a three-axis gyroscope sensor, and may implement an instability detection process based on information obtained via the sensor. The instability detection process may include, for example, a BID algorithm that may be implemented by the AFTU to monitor the angular rate of the vehicle, determine whether the vehicle is no longer under stable control, and issue a termination command upon detection of a termination condition.

    本公开描述了自主飞行安全系统(AFSS),其结合了使得能够对用于激活飞行终止系统(例如,在检测到终止条件的情况下)的各种终止条件进行AFSS监控的自主飞行终止单元(AFTU)。此类终止条件包括边界限制检测(例如,运载工具位置是否在规划的飞行包线之外或被计划在规划的飞行包线之外),以及箭体不稳定性检测(例如,俯仰速率和偏航速率是否超过指示运载工具不稳定性的某个阈值)。例如,AFTU可结合三轴陀螺仪传感器,并且可基于经由该传感器获得的信息来实施不稳定性检测处理。不稳定性检测处理可包括例如BID算法,其可由AFTU实施以监控运载工具的角速率、确定运载工具是否不再处于稳定控制下,并且在检测到终止条件时发出终止命令。
