Abstract: A system for controlling turbulence of fluid flowing past a window includes an imaging device compartment defining an interior and an exterior separated by a window, wherein the window encloses at least a portion of the interior, wherein the exterior includes at least one turbulator on a side upstream of the window positioned to induce turbulence over the entirety of a boundary layer of the fluid flowing past the window for even heat transfer between the fluid and the window.

Abstract: An aircraft pod can include a pod shell defining a window, a radar system disposed within the shell and in optical communication with the window in the shell, and configured to send and/or receive radar signals away from the pod shell in a radar field of regard, and a ram air inlet structure disposed on an outer surface of the shell in optical communication with the radar field of regard, wherein the ram air inlet structure is made of or coated with a radar absorbing material.
