Blade optimization problem
Hi David, I have a question. When I design the rotor of a drone using PROP mode and then optimize it, why can’t I fill in the lift-to-drag ratio? Thank you.
Hi Yizhan,
for propellers a different optimization algorithm is used compared to HAWT or VAWT blade optimization.
The optimization algorithm is presented in:
Adkins, C.N., Liebeck R.H. “Design of Optimum Propellers”, Journal of Propulsion and Power”, 1994
Best regards,
David
Thanks, David. I’m researching drone rotor noise, and after completing the BEM module, when I try to use the PNoise module to calculate noise, I can only select 2D Noise Simulation and cannot load BEM Data to create a 3D noise simulation. What could be the problem? Thank you.

Hi,
only the 2D airfoil-self noise calculation exists.
There is no functionality for 3D noise calculations implemented in QBlade.
Best regards,
David
Okay, thank you, David.
