Struct DragOverride 

pub struct DragOverride {
    pub coefficient: f64,
    pub include_children: bool,
}

A drag coefficient stated in place of the one a component’s geometry gives: OpenRocket’s drag-coefficient override (<overridecd>, <overridesubcomponentscd>), as OpenRocket 24.12 flies it, measured on probe designs (validation/oracles/openrocket/drag_override.py, ADR-167):

• The coefficient is on the rocket’s reference area and is the same at every Mach number.
• It replaces all the component’s own zero-lift drag: skin friction, pressure drag and the base drag of its aft face, whether that is the rocket’s base or a step down to the part behind it. A step up at its fore end is its own face, and goes too.
• It counts once per instance: per fin of a fin set, per lug or button of a set.
• On a tube fin set, a pod set or a part in a pod, or covering a pod set, it was not measured, and hpr-aero refuses it by name.
• With include_children, the parts attached to the component have no drag of their own.
• On a part inside the body (an inner tube, a ring, a mass) it does nothing, as such a part has no drag.
• On a stage, it is added to the rocket’s drag; with include_children, it replaces the drag of everything in the stage.

Fields

coefficient: f64

The zero-lift drag coefficient, on the rocket’s reference area, per instance. Zero is a value: no drag at all.

include_children: bool

Whether the parts attached to the component (or everything in the stage) lose their own drag too.

Trait Implementations

impl Clone for DragOverride

fn clone(&self) -> DragOverride

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DragOverride

impl Debug for DragOverride

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DragOverride

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for DragOverride

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for DragOverride

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
