Abstract

Autonomous Flight Termination Systems (AFTS) are used to terminate potentially dangerous trajectories of flight vehicles and rockets before they impose an unacceptable risk to humans or assets. In the FTSnext project a system design and software prototype of an AFTS specifically for the international market of orbital microlaunchers was developed. The system design was obtained following the model-based system engineering approach. The onboard software prototype was implemented in MATLAB. Furthermore, a simulator was developed in Simulink and ASTOS to test the AFTS in nominal, failure, and near-failure trajectories. In all simulated failure trajectories, the FTSnext prototype triggers the desired termination action. The adaptability to several launchers and nominal trajectories can be shown. The performance of the core functions sensor fusion and instantaneous impact point calculation were assessed with Monte Carlo simulations.

为法规各异的国际市场设计自主飞行终止系统

自主飞行终止系统（AFTS）用于在飞行器和火箭对人类或资产造成不可接受的风险之前终止其潜在的危险轨迹。在 FTSnext 项目中，开发了专门针对国际轨道微型发射器市场的自动飞行终止系统的系统设计和软件原型。系统设计采用了基于模型的系统工程方法。机载软件原型用 MATLAB 实现。此外，还在 Simulink 和 ASTOS 中开发了一个模拟器，以测试 AFTS 的额定、失效和濒临失效轨迹。在所有模拟失效轨迹中，FTSnext 原型都触发了所需的终止动作。可以显示出对多个发射器和额定轨迹的适应性。通过蒙特卡罗模拟评估了传感器融合和瞬时撞击点计算等核心功能的性能。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
