pub fn ring_center_fraction(aspect_ratio: f64) -> Result<f64, AeroError>Expand description
A thin ring’s aerodynamic center aft of its leading edge, as a fraction of its length, at an
aspect ratio A = d/L: THIN_RING_CENTER interpolated linearly in A, and held at A = 3
beyond it (TubeFinSetAero::new refuses a ring that short).
§Errors
AeroError::Domain for an A that is not finite and positive.
