Dear friends, I am looking for CAD model of ROBIN helicopter fuselage model. I am willing to study the interaction between a surface combatant and this helicopter model. THere are some technical reports of NASA for the generation of geometric shape. However, when I try this, some coefficients become complex numbers and I could not continue . If anyone already has this CAD model in any format like iges, step etc., I would be appreciated to get it.

Thanks in advance.

We found those same issues with the published data, and decided to compile all of the published corrections, along with re-cast formulae which avoid numerical errors, in an open github repository. We hope this helps.
