I am taking on a project to build composite rotor blades by following instructions
outlined in the file attached.
My understanding is that it is 3 step process.
1. Make 1 meter long piece shell from NACA profile.
2. Join 7 meter long shells by inserting epoxy glass and foam and 7 meter long lead rod.
3. Finally place the 70mm by 100 aluminium at one end. Wrap both pieces in carbon fibre fabric and seal them using resin infusion vacuum process.
This document is very old can you please confirm that if I am missing something
And what is the recommended resins one should use.
