An exposed main landing gear (26) cavity (48, 70) in a bottom wall of an aircraft fuselage (12) may include a main landing gear cavity outer ring (74) recessed within the fuselage and having an inner surface (76) encircling the main landing gear cavity, first baffle (84) extending inward from the outer ring inner surface at an aft and inboard position on the inner surface, and a second baffle (86) extending inward from the outer ring inner surface at an aft and outboard position on the outer ring inner surface. The main landing gear cavity may further include an aft fairing (58) disposed proximate the outer ring bottom edge of the outer ring and connected to the fuselage at an aft side of the main landing gear cavity. An aft fairing top surface (94) may have curvature causing the top surface to extend downward away from the outer ring as the top surface extends inward away from the outer ring.
