RocketSmith：高性能火箭的自主式增材製造

摘要

RocketSmith 是一套自主系統，能智慧化地自動執行適合發射之高性能火箭的 DFAM 流程。該系統利用大型語言模型來協調軟體工具的執行，以驗證飛行穩定性等設計特性，並生成火箭組裝所需的參數化設計元件。透過一系列子代理與技能，該系統能夠在零樣本與人在迴路兩種工作流程中，經由迭代實現飛行參數的最佳化。利用此系統，我們開發了四款採用不同引擎與組裝配置的高性能火箭，充分運用積層製造的獨特設計能力。這些組裝元件以多種 FDM 印表機製造，經人工評估飛行就緒度，並在發射活動中進行飛行測試。測試結果顯示，所有火箭均達到穩定發射，其中兩枚火箭成功回收且具備重新飛行的條件。高度計數據證實，火箭實際達到的頂點高度為自主系統預測值的 80%，確立了模擬與實驗之間的一致性。

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.
