Struct Rocket 

pub struct Rocket { /* private fields */ }

Base structural mass plus an ordered set of stages.

Total mass is analytic in simulation time: the base mass, the dry mass of every attached stage and the remaining propellant of every attached motor. Thrust is the sum over attached, currently burning motors, so serial and parallel (strap-on) staging share one model. Motor knots, ignitions, burnouts and separations all split the integration grid.

Implementations

impl Rocket

pub fn new(dry_mass_kg: f64, motor: Option<Motor>) -> Result<Self>

A single-stage vehicle whose optional motor burns once and stays attached. Dry mass includes the empty motor casing. None creates a ballistic body.

pub fn staged(base_mass_kg: f64, stages: Vec<Stage>) -> Result<Self>

A multi-stage vehicle. base_mass_kg is the structure that never separates (payload, bus, final casing) and must be positive.

pub fn dry_mass_kg(&self) -> f64

Mass that never separates: for Rocket::new the full dry mass including the motor casing; for Rocket::staged the final mass after every stage has separated and all propellant is spent.

pub fn motor(&self) -> Option<&Motor>

The single permanent motor of a Rocket::new vehicle. Staged vehicles use Rocket::stages; this returns Some only for the single-motor shape.

pub fn stages(&self) -> &[Stage]

All stages in the order supplied at construction.

pub fn sample(&self, time_s: f64) -> Result<RocketSample>

Evaluate mass and aggregated motor output at a finite nonnegative time.
