RocketSmith：高功率火箭的自主增材制造

摘要

RocketSmith 是一种智能代理系统，可自动执行适用于高功率火箭开发的增材制造设计（DFAM）流程。该系统利用大型语言模型协调软件工具的执行，以验证飞行稳定性等设计特性，并生成火箭组件的参数化设计部件。通过零样本与人在回路工作流程的迭代优化，子代理与技能集合可实现对飞行参数的优化。利用该系统的独特增材制造设计能力，开发了四种不同发动机与组件配置的高功率火箭。这些组件通过多种FDM打印机完成制造，经人工评估具备飞行条件后，在发射活动中进行了飞行测试。试验结果显示，所有火箭均实现稳定发射，其中两枚火箭成功回收至可重新飞行的状态。高度计数据验证了实际飞行高度达到代理系统预测理论远地点高度的80%，确立了仿真与实验间的一致性。

RocketSmith is an agentic system which intelligently automates the DFAM process for the development of high powered rockets suitable for launch. The system utilizes a large language model to orchestrate the execution of software tools to validate design characteristics such as flight stability and generate the parametric design components for the rocket assembly. A collection of subagents and skills enable optimization workflows of flight parameters via iteration in both zero-shot and human-in-the-loop workflows. With this system, four distinct high power rockets with various motor and assembly configurations were developed utilizing the unique design capabilities of additive manufacturing. These assembly components were fabricated using various FDM printers, manually evaluated for flight readiness, and flight tested at a launch event. From these tests, all rockets achieved a stable launch and two of the four rockets were successfully recovered in reflyable condition. The altimeter data validated that the rockets achieved an altitude 80% of the expected apogee predicted by the agentic system, establishing consistency between simulation and experimentation.
