Struct DragParameters 

pub struct DragParameters { /* private fields */ }

Validated drag parameters that can be stored on propagator configs.

Implementations

impl DragParameters

pub fn from_area_mass( cd: f64, area_m2: f64, mass_kg: f64, sw: SpaceWeather, cutoff_altitude_km: f64, ) -> Result<Self, PropagationError>

Build from drag coefficient, cross-section area, mass, and cutoff.

pub fn from_bc_factor_m2_kg( bc_factor_m2_kg: f64, sw: SpaceWeather, cutoff_altitude_km: f64, ) -> Result<Self, PropagationError>

Build directly from B = C_D * A / m in m^2/kg.

pub fn from_ballistic_coefficient( bc_kg_m2: f64, sw: SpaceWeather, cutoff_altitude_km: f64, ) -> Result<Self, PropagationError>

Build from reciprocal ballistic coefficient BC = m / (C_D * A).

pub fn from_area_mass_default_cutoff( cd: f64, area_m2: f64, mass_kg: f64, sw: SpaceWeather, ) -> Result<Self, PropagationError>

Build from drag coefficient, area, and mass with the default cutoff.

pub fn to_force(self) -> DragForce

Convert to a force model without revalidating.

pub fn bc_factor_m2_kg(&self) -> f64

Drag ballistic-coefficient factor B = C_D * A / m, m^2/kg.

pub fn space_weather(&self) -> SpaceWeather

Space-weather inputs used for density evaluation.

pub fn cutoff_altitude_km(&self) -> f64

Density cutoff altitude, km.

Trait Implementations

impl Clone for DragParameters

fn clone(&self) -> DragParameters

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for DragParameters

impl Debug for DragParameters

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DragParameters

fn eq(&self, other: &DragParameters) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
