Abstract
A pre-diffuser may include a plurality of struts, and each strut may have a leading edge. An upper contour of the leading edge may have a forward end and an aft end, and may include a first radius and a second radius. The first and second radii may be associated with the forward end and the aft end, respectively. The first radius may also be located farther forward than the second radius, and may be larger than the second radius.
