  • Hi Andy. In order to design the planform of my delta project, i need to obtain the spanwise lift distribution at cruise speed, over several iterated planforms until i achieve something aproximately eliptical. i am having a hard time finding papers on lift distributions that work on low AR and sweep and where the mathematical complexity is reasonable.
    Would openfoam be appropiate for such a task?

    I am aware that an eliptical distribution is not feasible in a high sweep low AR delta, however an eliptical should be a benchmark and i would like to be able to check deviations, specially at the tips.

    @berridos, I use Solidworks for doing geometry. You could use anything that can generate an STL file but it's nice to use a parametric modeler because you can iterate geometry relatively quickly. It's a steep learning curve to tackle though! OF with inviscid flow sim will tell you lots - you need to keep the process as simple as you can to do the job needed.

    Andy, thx a lot. Have been reviewing lots of info and tutorials on xlfr5 and openfoam and your proposed route seems perfect. For some reason in the tutorials they dont recommend solidworks for the stl because of the tringle quality and catia is a unaffordable. Will give a try to blender. Did you have any problerms meshing your geometries from solidworks in of?
