Struct RailForces 

pub struct RailForces<F> { /* private fields */ }

Launch-rail constraint: a force-model wrapper that projects environmental acceleration onto the rail direction while the vehicle is on the rail.

The rail is a segment starting at origin_m and running length_m along direction. If the initial velocity is zero or along the rail, motion stays exactly on the rail because every acceleration is collinear with it. After rail exit the inner model passes through unchanged. Command the thrust axis along the rail and no steering until exit; pair with crate::ballistics::BallisticForces::with_tipoff_yaw for the exit disturbance.

Implementations

impl<F> RailForces<F>

pub fn new( inner: F, origin_m: Vec3, direction: Vec3, length_m: f64, ) -> Result<Self>

Build a rail. direction is normalized at construction and must be nonzero and finite; length_m must be finite and positive.

Trait Implementations

impl<F: Clone> Clone for RailForces<F>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: Debug> Debug for RailForces<F>

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

Formats the value using the given formatter.

impl<F: ForceModel> ForceModel for RailForces<F>

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

Acceleration in world-frame metres per second squared.

fn acceleration_with_axis( &self, state: &FlightState, mass_kg: f64, body_axis: Vec3, ) -> Result<Vec3>

Acceleration when the commanded body axis is known, for angle-of-attack-aware models (body lift, induced drag). body_axis is the solver-resolved unit thrust axis at this stage. The default ignores the axis, which keeps every orientation-blind model (gravity, plain drag) bit-identical.
