Struct PodFins 

#[non_exhaustive]
pub struct PodFins {
    pub roll_rad: Vec<f64>,
    pub axis_roll: [FinRollTerms; 2],
    pub fins: u32,
}

A pod’s fin set flown once per pod (FinSetAero::pods).

Serialize-only, like AeroModel.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

roll_rad: Vec<f64>

Each copy’s turn about the rocket’s axis, rad, from x_B toward y_B: a pod turns what it holds with it (hpr_design::Placement), so copy k’s fin j stands at θ_j + roll_k.

axis_roll: [FinRollTerms; 2]

Every fin of every copy, N of them, is ρ_i from the rocket’s axis at its root, along its span: ρ = o · ê + r_t, with o the copy’s offset, ê the fin’s direction and r_t the pod’s tube radius. A fin’s roll damping is quadratic in ρ (FinAero::roll_terms, ∫(ρ + y)² …), so the sum over the fins is N/2 times the damping at μ + σ plus that at μ − σ, with μ and σ the mean and the standard deviation of the ρ_i: these two terms, exactly. Their body_radius_m is that offset, which may be negative, and only their damping means anything: a pod’s fins are never canted. FinSetAero::roll is not used for a pod’s fins. The whole sum takes the pod tube’s roll-damping interference k_R(B), exact for fins on a pod of no radius, where it is 1 (docs/physics/aero.md, Pods).

fins: u32

N, the fins over all the copies.

Trait Implementations

impl Clone for PodFins

fn clone(&self) -> PodFins

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PodFins

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

Formats the value using the given formatter.

impl PartialEq for PodFins

fn eq(&self, other: &PodFins) -> 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.

impl Serialize for PodFins

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
