Anti-shock body

An anti-shock body is a streamlined pod positioned on the upper surface of a wing to reduce wave drag while travelling at transonic speeds (Mach 0.8–1.0), which includes the typical cruising range of conventional jet airliners. Also known as a Whitcomb body, Küchemann carrot or speed bump, it improves area rule distribution.

The anti-shock, or shock, body was one of a number of ways of implementing what was then the recently developed area rule. Another was fuselage shaping.
