Retrieval-Augmented Generation and In-Context Prompted Large Language Models in Aircraft Engineering, AIAA-2025, AIAA, doi:10.2514/6.2025-0700 Abstract: With the aerospace industry taking its first steps towards exploiting the rapidly evolving technology of Large Language Models (LLMs), this study explores the potential of the latest generation of LLMs to become an effective link in the aircraft design tool chain of the future. Our focus is on the task of Question Answering (QA) in engineering, which has the potential to augment future aircraft design team meetings with an intelligent LLM-based agent able to engage with the team via a chatbot interface. We compare three of the most effective and popular classes of LLM QA prompting today – LLM zero-shot prompting, LLM in-context prompting and LLM-based Retrieval-Augmented Generation (RAG). We describe a new, low volume, high quality benchmark aircraft design QA dataset (AeroEngQA) and use it to qualitatively evaluate each class of LLM and exploring properties including answer accuracy and answer simplicity of the answer. We provide domain-specific insights into the usefulness of today’s LLMs for engineering design tasks such as aircraft design, and a view on how this might evolve in the future as the next generation of LLMs emerges.
