Free Software: Korn’s relation is a simple algebraic method to estimate the Mach number at which an airfoil will first exhibit a drag rise due to compressibility, based on the airfoil’s design lift coefficient and thickness. This utility application also converts the calculated drag divergence Mach number into various units compensated for ambient temperature. This application is “unsigned” meaning that you’ll probably need to click through some warning dialog boxes in order to “approve” installing and running the application.
