Question about rcas_input.dat file in anl_blade_cs_rcas example

[kimjihun8]

Can you explain AERONODE, AEROSEG, AIRFOILINTERP in that file?

1. I understand Blade nodes, but I don't know what AERONODE represents.
2. I don't know what Aerodyn and Node IDs in AEROSEG represent exactly.
3. In AIRFOILINTERP, in the Radial/Spanwise section, what value does radial refer to?
   Does the value called spanwise refer to the spacing of the crosssection created in the input?
