1. An assembly for an aircraft propulsion system having an axial centerline, the assembly comprising:
an upstream cowl extending circumferentially about the axial centerline, the upstream cowl further extending axially from a first upstream end to a first downstream end, the upstream cowl including an inner barrel panel, an outer barrel panel, and a bulkhead, the bulkhead extending radially between and connecting the inner barrel panel and the outer barrel panel at the first downstream end; and
a downstream cowl extending circumferentially about the axial centerline, the downstream cowl further extending axially from a second upstream end to a second downstream end, the second upstream end positioned axially adjacent the first downstream end, the downstream cowl including a cowl panel and a seal assembly, the cowl panel being movable between an open position and a closed position, the seal assembly including a seal frame and a seal member, the seal frame including an oblique portion and a seal frame axial portion, the seal frame mounted to the bulkhead radially inward of the cowl panel, the seal member mounted to the cowl panel, the seal member including a seal member radial portion projecting away from the cowl panel to a distal end of the seal member radial portion, the seal member radial portion located at the second upstream end, and the oblique portion located axially between the bulkhead and the seal frame axial portion, the oblique portion axially aligned with the seal member radial portion;
wherein, with the cowl panel in the closed position, the distal end is radially spaced outward of the oblique portion.
