The sweep angle of an aircraft’s wing affects its aerodynamic characteristics, particularly the maximum lift coefficient (Cl max) and critical Mach number. A swept-back wing delays the onset of compressibility effects at high speeds, which can increase the critical Mach number.
The relationship between sweep angle and Cl max is complex and depends on various factors such as aspect ratio, Reynolds number, and Mach number. Generally, a higher sweep angle reduces the maximum lift coefficient due to reduced effective camber at high angles of attack.
The critical Mach number (Mcr) is influenced by the sweep angle through its effect on wave drag. A swept-back wing can significantly increase Mcr, allowing for higher speeds before compressibility effects become significant.
