Fields

designation: String

Material designation.

tid_threshold: f64

Total ionizing dose (TID) threshold for property change (Gy).

d_alpha_per_mrad: f64

tml_percent: f64

Outgassing total mass loss fraction (TML, %).

cvcm_percent: f64

Collected volatile condensable material (CVCM, %).

ao_erosion_yield: f64

Atomic oxygen (AO) erosion yield (cm³/atom).

ao_fluence_leo: f64

AO fluence at LEO per year (atoms/cm²/year).

alpha_initial: f64

Material initial absorptance α0.

emissivity: f64

Material emissivity ε.

Implementations

impl SpaceEnvironmentEffects

pub fn kapton_hn() -> Self
