Drag divergence mach number
WebWing sweep reduces drag when the aircraft flies with transonic or supersonic speed. Now the Mach effects depend only on the normal speed component, so they are proportional to the cosine of the sweep angle. … WebAug 3, 2010 · The Mach number at which the no-lift drag coefficient has risen by a small fixed percentage above the low Mach number value is known as the ‘drag critical Mach …
