Struct FinRollTerms 

#[non_exhaustive]
pub struct FinRollTerms {
    pub body_radius_m: f64,
    pub reference_diameter_m: f64,
    pub first_moment_m3: f64,
    pub second_moment_m4: f64,
    pub transonic_start: FinRoll,
    pub supersonic_start: FinRoll,
}

One fin’s roll terms on one body that don’t change with Mach (FinAero::roll_terms): its span moments about the axis and the ends of the transonic join, built once per fin set.

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.

body_radius_m: f64

Radius of the body at the fins, m: where the strips start from the axis. For a fin on a pod, taken about the rocket’s axis, its root’s offset from that axis along its span.

reference_diameter_m: f64

Reference diameter, m.

first_moment_m3: f64

∫ξ dA, m³ (FinOutline::axis_moments).

second_moment_m4: f64

∫ξ² dA, m⁴.

transonic_start: FinRoll

The roll at Mach 0.8, where the join starts.

supersonic_start: FinRoll

The roll at M_s, where linear theory starts.

Trait Implementations

impl Clone for FinRollTerms

fn clone(&self) -> FinRollTerms

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FinRollTerms

impl Debug for FinRollTerms

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

Formats the value using the given formatter.

impl PartialEq for FinRollTerms

fn eq(&self, other: &FinRollTerms) -> 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 FinRollTerms

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
