Teardrop wing / motor fairing — OpenFOAM `forceCoeffs` (all case folders)

Order: highest teardropv number first. Case folders whose names include with_hubshield are omitted. One row per listed OpenFOAM case directory under the repo (name starts with teardrop, ends with _sim or Simulation).

Machine-readable: teardrop_force_coeffs_results.json. Design constraints (span, thickness, Z): design_constraints.md. Payload fairing hub (same visual design): payload fairing 205×92 index.

Simulation setup (typical)

OpenFOAM 13, steady incompressible RANS, SST k–ω where cases are complete; forceCoeffs reference values from each case file header (magUInf, Aref, lRef). Drag column: Cd × ½ρU²Aref with ρ = 1.225 kg/m³ and U = magUInf from the file (speed differs between cases).
