About this document
Understanding Drag Divergence Mach Number by Bijin Chadayan is a document available to read on EtoBox.
The drag divergence Mach number is the speed at which an airfoil begins to experience a rapid increase in aerodynamic drag as speed increases further. This is caused by shock waves forming on the top surface of wings, which can induce flow separation and spikes drag coefficient to over 10 times its low speed value. Aircraft intended for transonic and supersonic flight require powerful thrust to overcome this steep rise in drag near Mach 1. Technological advances like area ruling and supercritical airfoils h
