Struct TubeFinSetAero 

#[non_exhaustive]
pub struct TubeFinSetAero {
    pub id: String,
    pub count: u32,
    pub fore_station_m: f64,
    pub length_m: f64,
    pub mean_diameter_m: f64,
    pub axis_radius_m: f64,
    pub area_ratio: f64,
}

A tube fin set’s precomputed terms.

Serialize-only, like crate::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.

id: String

The component’s id.

count: u32

Number of tubes, at least 3.

fore_station_m: f64

Station of the tubes’ leading edges, m aft of the nose tip.

length_m: f64

A tube’s length L, m.

mean_diameter_m: f64

A tube’s mean diameter d, m: its outer and inner radii added.

axis_radius_m: f64

Distance of each tube’s axis from the rocket’s axis, m: the body’s radius plus the tube’s outer radius.

area_ratio: f64

One tube’s area d L over the reference area.

Implementations

impl TubeFinSetAero

pub fn new( component: &PlacedComponent, set: &TubeFinSet, reference_area_m2: f64, ) -> Result<Self, AeroError>

The terms of set on component, on a rocket of reference area reference_area_m2.

Errors

AeroError::Unsupported for fewer than three tubes, solid tubes, tubes shorter than a third of their diameter (past Fletcher’s measurements) and tubes that overlap their neighbours; AeroError::Layout for a set without the radius of its body tube, and AeroError::Domain for a bad dimension.

pub fn loading(&self, mach: f64) -> Result<(f64, f64), AeroError>

The whole set’s normal-force slope per radian on the reference area at mach, and its center of pressure, m aft of the nose tip: N C_Lα(λ/β)/β · d L/A_ref at x_ac(β A) L behind the leading edge.

Errors

AeroError::Mach outside [0, 0.8).

pub fn roll_damping( &self, mach: f64, reference_diameter_m: f64, ) -> Result<f64, AeroError>

The set’s roll damping C_lp at mach on a reference diameter reference_diameter_m: each tube crosses the air at p ρ under the roll rate p, ρ its axis’s distance from the rocket’s, so its normal force about the axis gives −2 C_Nα ρ²/d², as a pod’s does (crate::AeroModel::roll).

Errors

As Self::loading.

Trait Implementations

impl Clone for TubeFinSetAero

fn clone(&self) -> TubeFinSetAero

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TubeFinSetAero

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

Formats the value using the given formatter.

impl PartialEq for TubeFinSetAero

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
