optimizes an Airfoil for a blended wing body using cfd analysis with su2 and optimization by openMdao

airfoil optimization for BwB

This program implements an openMdao component, that optimizes an airfoil for minimum drag while making sure a defined rectangle is still fitting inside it. This rectangle represents the cabin tube of a blended wing body (BwB).

Requirements:

• python:
  • the tested versions are 2.7 and 3.5
  • beside some standard packages openMdao is needed
    • http://openmdao.org/
• su2:
  • https://su2code.github.io/download.html
  • the version used here is: 6.0.0 "Falcon"
• construct2d(recommended):
  • https://sourceforge.net/projects/construct2d/
  • the version used here is: 2.1.4
• or gmsh:
  • http://gmsh.info/
  • the version used here is: 3.7.5

Setup:

Set the paths to your binaries in config.py. Note, this program is designed for Windows!

How to run it:

use your favourite python editor and open this repo as a new project.

• main.py: the main optimization program
• cfdTestRun.py: simple test script that runs one cfd job with a given input airfoil coordinate file
• airofilAnalysisMach.py: runs analysis on one airfoil, generates drag over mach for one liftcoefficient
• airofilAnalysisPolar.py: runs analysis on one airfoil, generates polar for one mach nr
• cfdConvergenceTest.py: does convergence analysis with different mesh sizes
