Properties

Chord: number (m)

The chord of the blade at this section, measured from leading to trailing edge. The section will be positioned such that the aerofoil's quarter chord position will lie on the aerodynamic axes origin.

ThicknessToChordRatio: number

The ratio between the thickness and the chord length at the section. This would be 1.0 for a cylinder, and in the order of 0.1 (or 10%) for a typical slender aerofoil section.

AerodynamicSection: string (CrossReference)

A reference to an aerofoil, interpolated aerofoil, or aileron aerofoil to use for this section.
