Abstract
A golf club incorporating a trip step feature located on the crown section. The benefits associated with the reduction in aerodynamic drag force associated with the trip step may be applied to drivers, fairway woods, and hybrids. A portion of the trip step is located between a crown apex and the back of the club head and may be continuous or discontinuous. The trip step enables a reduction in the aerodynamic drag force exerted on the golf club by forcing the air passing over the club head from laminar flow to turbulent flow prior to the natural separation point of the airstream from the crown. This selectively engineered transition from laminar to turbulent flow over the crown section slightly increases the skin friction but results in less aerodynamic drag than if the air were to detach from the crown section at the natural separation point.
