Abstract
An aerodynamic structure comprising a series of shock bumps () extending from its surface. The shock bumps are distributed across the structure with a non-uniform spacing (d, d) between the centers and/or edges of adjacent bumps. The non-uniform spacing between the bumps can be arranged to give maximum wave drag alleviation for the minimum number of bumps as a function of the shock strength across the span, leading to minimum wing weight penalties for a given amount of wave drag alleviation.
