• Aerodynamic Centre of an aircraft

    Hi, I was wondering if there is an efficient way to determine the aerodynamic centre of an aircraft. I set up a model of the aircraft where drag is in the Z direction and lift is in the Y direction. I set up a grid of...

  • Improvements in separated flow at low angles since 2012?

    Good afternoon fellow Flowheads,   I've been using Flowsim 2012 at home since 2012 to investigate flow over a subsonic aircraft. I was told many years ago that the drag and lift for separated flow at a low separ...
