Sets of four wing profiles for studying the laws of aerodynamics. They can be used with aerodynamic balances of the EI 400 series. They exist with two spans: 230 mm (EI402) and 300 mm (EI403).
4 types of NACA profiles, with the following references :
The profiles have a rope (depth) of 100mm. They are equipped with an axis (Ø = 0mm) to adjust their incidence. This axis is located from the leading edge to :
Supplied with complete technical bulletin including the dimensional characteristics of the wing profiles, an educational file with experimental-type results.
