A RANS-Derived Aerodynamic Database and Surrogate-Based Longitudinal Stability and Trim-Envelope Assessment of a Tailless Cropped-Delta UCAV

Supporting data and code for the manuscript "A RANS-Derived Aerodynamic Database and Surrogate-Based Longitudinal Stability and Trim-Envelope Assessment of a Tailless Cropped-Delta UCAV". The release contains the 36-case steady-RANS aerodynamic database (CL/CD/Cm per case with per-case residual and symmetry states), grid-convergence data, the calibrated Kriging surrogate, all MATLAB scripts for surrogate fitting, longitudinal-stability metrics, and Monte-Carlo uncertainty propagation, the parametric geometry and gmsh meshing scripts, the manuscript, and the full figure set. Running the included "run_all" pipeline re-derives every key number reported in the paper (neutral point, static margin, aft centre-of-gravity limit, pitch-up onset, MC quantiles, trim conditions).
