Summary

A new LLM-based visual programming copilot application has been developed for aerospace engineering design tasks, utilizing a visual programming variant of the ReAct methodology and GPT 5.4. This system addresses the aerospace industry's need for explainable and safe AI tools, where no commercial LLM-based geometric design copilots are currently in use by OEMs. The project also introduces Wingbuilder, a new Grasshopper plugin library offering custom components for aerospace-specific geometry abstraction, and the Aerospace Visual Programming Dataset (AVPD), comprising 18 expert-designed aerospace tasks with ground truth solutions. A user trial with two experienced aerospace engineers from a major aircraft manufacturer indicated that the copilot's ReAct methodology successfully generated helpful suggestions. While participants expressed willingness to use the tool, slow ReAct inference times currently limit its practical utility to more complex, time-consuming tasks where the wait for a solution is justified.

Key takeaway

For aerospace engineers evaluating AI tools for geometric design, this copilot demonstrates the potential of LLM-based visual programming, particularly for complex, time-consuming tasks. You should consider integrating such tools, especially those with domain-specific libraries like Wingbuilder, but be mindful of current inference speed limitations. Prioritize solutions that offer explainability and safety, aligning with industry standards, and assess if the wait time for suggestions is justified by task complexity.

Key insights

LLM-based visual programming copilots can assist aerospace geometric design, but inference speed remains a practical challenge.
