SEALING ASSEMBLY FOR REDUCING GAPS BETWEEN MOVABLE CONTROL SURFACES OF AN AIRCRAFT

Abstract

The invention is a sealing assembly for reducing the gap between an aircraft's movable flight control member and adjacent structure thereto, the flight control member and structure having external surfaces and side surfaces facing each other. In detail, the assembly includes first and second flexible bulb seals mounted on the periphery of the side surface of both the flight control member and the adjacent structure forming an extension of the external surface of both. Each of the bulb seals includes a compressible foam bulk absorber core; the core having a bottom surface, a top surface generally parallel to the bottom surface, an outer side surface, and an inward facing surface at an acute angle to the top surface. A first sheet of dielectric material is bonded to the bottom surface of the core. A second sheet of flexible resistive material is bonded to the top, and sides of the core. A third sheet of flexible magnetic radar absorbing material is bonded to the second sheet. A fourth sheet of flexible abrasion resistant material is bonded over the third sheet.
