The airfoil geometry is fully parametric and the app incorporates the Optimization interface to find the wing geometry parameters that maximize the lift-to-drag ratio. The NACA 2412 is the default airfoil in this app. Its maximum thickness is 12% of the chord. The NACA 2412, for instance, is an airfoil with a maximum camber of 2%, located at 40% of the leading edge. The last two digits describe the maximum thickness of the airfoil as a percentage of the chord.The second digit describes the distance of maximum camber from the airfoil’s leading edge in tenths of the chord.The first digit describes maximum camber as a percentage of the chord.The naming convention for the airfoil is as follows: The four-digit NACA airfoil is an airfoil shape developed by the National Advisory Committee for Aeronautics (NACA), the precursor to the National Aeronautics and Space Administration (NASA). The NACA Airfoil Optimization app allows for the computation of the lift and drag forces on a fully parameterized NACA airfoil. Let’s get started… The Capabilities of the NACA Airfoil Optimization App A force known as lift holds airplanes aloft by opposing the weight of the airplane, thus enabling these machines to soar high above the ground.īy being able to easily compute lift and drag forces on an NACA airfoil with a customized simulation app, we can optimize these designs for aeronautical applications. While modern airplanes may fly much farther than the Wright brothers’ plane, they still obey the same laws of physics. Since that time, we have continued to take to the air, with airplanes growing in size and strength. The Wright brothers were aviation pioneers, flying the first powered airplane in 1903. This groundbreaking moment marked the world’s first successful powered flight. Orville Wright took control of the plane and, making history, flew for 12 seconds across a distance of 120 feet. On a windy December morning in 1903, the Wright brothers prepared to make an attempt at flight in Kitty Hawk, North Carolina. Lifting off the Ground and into the Skies In this blog post, we discuss how the app can be used for production applications and how you can benefit from using the Application Builder to enhance your own models and apps. To accurately compute lift and drag forces and optimize any airfoil following the NACA naming convention, COMSOL Multiphysics version 5.2 includes a new example, the NACA Airfoil Optimization app.
