Struct ThrustCurve 

pub struct ThrustCurve { /* private fields */ }

Validated, piecewise-linear thrust curve with exact piecewise-quadratic impulse.

Implementations

impl ThrustCurve

pub fn new(points: Vec<ThrustPoint>) -> Result<Self>

Construct from at least two strictly time-ordered samples, starting at zero. Total impulse must be positive. Endpoint thrust need not be zero; the integrator explicitly handles the discontinuities at ignition and burnout.

pub fn points(&self) -> &[ThrustPoint]

Read-only access to the validated samples.

pub fn duration_s(&self) -> f64

Time of the last sample, in seconds after ignition.

pub fn total_impulse_ns(&self) -> f64

Integral of thrust over the entire curve, in newton seconds.

pub fn thrust_at(&self, elapsed_s: f64) -> Result<f64>

Interpolated thrust. Returns zero outside the closed curve interval. At the final sample this returns the left-limit force; Motor::sample reports zero thrust at and after burnout instead.

pub fn impulse_at(&self, elapsed_s: f64) -> Result<f64>

Exact integrated impulse through this time, clamped to the curve interval.
