I want to compare different blade shapes and rotor designs in their lift force and torque by a specific rpm. For a calculation, I would need the lift coefficient, which i don't have for a self designed blade shape. How can I calculate this coefficient or have I to simulate this? And which software is recommended to simulate such kind of problem (the blades are designed in a CAD software)?
BTW: Is there any good source (books, online source,...) for aerodynamic formulas referring to rotors (helicopters), I didn't find something so far?
