pub const FORWARD_SWEEP_MACH: f64 = 1.0;Expand description
Where a forward-swept fin’s warning starts: Mach 1 (ADR-188). Its measured error is
a normal-force slope that rises by up to 7.7% past linear theory’s start, Mach 1.2
(hpr_aero::fins::SUPERSONIC_START_MACH), peaking up to 0.37 past it
(issue #64); the warning starts at the lowest
supersonic Mach number, below that rise. The transonic join into linear theory starts at Mach
0.8 (hpr_aero::fins::TRANSONIC_START_MACH); below Mach 1 the error isn’t measured.
