Detailed Description

Versioned create-info for a NACA 4-digit airfoil profile curve.

The generated profile lies in the XY plane with the leading edge at (0,0,0) and the chord along +X. Use curve transforms to place or scale it after construction.

Member Data Documentation

◆ camber_position

double occtl_curve_airfoil_naca4_info::camber_position

Position of maximum camber as a chord fraction in [0,1].
