§cna_vs_mach: Vec<(f64, f64)>

Normal-force slope per radian vs Mach.

§cp_vs_mach: Vec<(f64, f64)>

Centre of pressure, metres aft of nose, vs Mach.

§cg_dry_m: f64

Dry-structure CG, metres aft of nose.

§cg_prop_m: f64

Propellant CG, metres aft of nose.

§pitch_inertia_kg_m2: f64

Scalar pitch inertia about the CG, kg·m².

§induced_k_vs_mach: Vec<(f64, f64)>

Induced-drag factor per radian² vs Mach.

§recovery_cd_area_m2: f64

Recovery parachute Cd·A in m².
