Lift Distribution Plot AVL

[Cornelius Kauffmann]

Hello!

Is it possible to get a lift distribution plot using the data calculated by AVL? The internal plot function plot_lift_distribution() works fine for me with Fidelity Zero, but I am not able to get the plot to work for the analysis with AVL. However, I noticed in the source code that SUAVE is reading in the sectional lift distribution results obtained by AVL, so this should work somehow.

Thanks in advance!

Hi Cornelius,

It is possible. But there's a reason why it's not done.

AVL is a computationally expense analysis code to run for SUAVE. Therefore, SUAVE will run AVL before a mission and calculate results for a bunch of flight conditions. From those results surrogate models are built. However, these surrogate models don't save the full lift distribution for a mission.

So, yes, we do pull the lift distribution data out (because it's there). But then later it is discarded. So if you wanted to use SUAVE's ability to call AVL and plot_lift_distribution() you would need to do a little coding. Running AVL within a mission would take a very long time to converge. But you could just run AVL for a few angles and mach numbers and plot those.

Hi Emilio,
thank you for your helpful response, I'll try to do it that way.
