Abstract—Scientific discourse practices vary across disciplines and research designs. As a frontier field where experimental and simulation–based approaches are routinely combined, aerospace engineering provides a productive venue for examining how different research paradigms are linguistically realized. In this situation, this study compares transitivity patterning in experimental and simulation–based results within a Systemic Functional Linguistics framework. Two corpora were compiled from the AIAA Journal, including Results sections from ten experimental articles and ten simulation-based articles, totaling 27,701 and 24,485 tokens respectively. Using UAM CorpusTool 6.2.0, clauses were coded for process types, participant roles, and circumstance types. Distributional differences were tested in SPSS 26.0, and recurrent process-participant-circumstance configurations were qualitatively interpreted. The analysis shows broad convergence in circumstance profiles, indicating shared condition anchoring across research types. In contrast, systematic variation concentrates in the process-participant core: simulation results favor relational processes and carrier-centered realizations, whereas experimental results display a complementary prominence of material processes and more outcome–oriented role profiling. These findings suggest method–sensitive grammatical defaults shaped by model-based versus measurement-based evidential orientations and offer practical implications for concise, condition-explicit Results writing.
