Struct nyx_space::dynamics::drag::Drag

pub struct Drag {
    pub density: AtmDensity,
    pub drag_frame: Frame,
    pub cosm: Arc<Cosm>,
}

Drag implements all three drag models.

Fields

density: AtmDensity

Density computation method

drag_frame: Frame

Frame to compute the drag in

cosm: Arc<Cosm>

a Cosm reference is needed to convert to the state around the correct planet

Implementations

impl Drag

pub fn earth_exp(cosm: Arc<Cosm>) -> Arc<Self>

Common exponential drag model for the Earth

pub fn std_atm1976(cosm: Arc<Cosm>) -> Arc<Self>

Drag model which uses the standard atmosphere 1976 model for atmospheric density

Trait Implementations

impl Clone for Drag

fn clone(&self) -> Drag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ForceModel for Drag

fn eom(&self, ctx: &Spacecraft) -> Result<Vector3<f64>, NyxError>

Defines the equations of motion for this force model from the provided osculating state.

fn dual_eom(
    &self,
    _radius: &Vector3<Hyperdual<f64, U7>>,
    _osc_ctx: &Spacecraft
) -> Result<(Vector3<f64>, Matrix3<f64>), NyxError>

Force models must implement their partials, although those will only be called if the propagation requires the computation of the STM. The osc_ctx is the osculating context, i.e. it changes for each sub-step of the integrator.
