OTHER: Aerodynamics - Blade Profile

Overview:

Generic information on airfoils, which could be applicable to the SynchroLite and UniCopter.

Data, notes and comparisons on NACA 00xx, NACA 8-H-12, VR-x, VR-7b and NACA 230 series airfoils.

Plus Wortmann FX 74-CL5-140 for inverted use as horizontal stabilizer on UniCopter.

Note:

All of the above airfoils can be plotted c/w coefficients on NVFoil freeware program.

Graphs:

The 3 following graphs compare the 4 listed airfoils. The horizontal axis is Angle of Attack [alpha].
