Struct BallisticForces 

pub struct BallisticForces { /* private fields */ }

Gravity and aerodynamic drag delegated to ballistics-engine’s force kernel.

Implementations

impl BallisticForces

pub fn new( diameter_m: f64, cd_vs_mach: Vec<(f64, f64)>, atmosphere: Atmosphere, wind_mps: Vec3, ) -> Result<Self>

Build using the vehicle’s actual Cd curve, not a G-model reference curve or BC. At least two ascending, nonnegative Mach values and positive Cd values are required. Wind is a world-frame air velocity vector (positive X is a tailwind).

pub fn with_drag_scale(self, scale: f64) -> Result<Self>

Apply a positive multiplier to the entire Cd curve. Default is 1.0.

pub fn set_wind(&mut self, wind_mps: Vec3) -> Result<()>

Change uniform world-frame wind between public integration steps.

pub fn acceleration_in_wind( &self, state: &FlightState, mass_kg: f64, wind_mps: Vec3, ) -> Result<Vec3>

Evaluate using externally sampled wind, for a spatial or time-varying force wrapper.
