Abstract: A pneumatic fastening mechanism is provided for fastening an aircraft surface panel to an aircraft panel support member. The panel includes a plurality of receptacles extending from the panel lower surface. The panel support member includes a corresponding plurality of panel engagement mechanisms, disposed on the support member lower surface, and translatable through the support member to engage the receptacles. The panel engagement mechanisms are extendable from a first position, wherein the panel abuts and is engaged to the panel support member, to second position wherein the panel is elevated above the panel support member upper surface where the panel may be unlocked and separated from the panel engagement mechanism. The panel engagement mechanism is operative to elevate and release the panel in response to changes in fluid pressure communicated to the panel engagement mechanisms.

Abstract: A magnetic fastener assembly for securing an access panel to an aircraft structure. A panel magnetic foundation member is rigidly secured to a surface of the panel facing the aircraft structure and a land magnetic foundation member is rigidly secured to a surface of the aircraft structure facing the panel. A planar magnet is positioned between the panel magnetic foundation member and the land magnetic foundation member and being magnetically coupled thereto so as to secure the panel to the aircraft structure. A separation device, such as a pneumatic bladder, is positioned between the panel and the land structure and adjacent to the magnet, and is rigidly secured to the aircraft structure. The separation device is actuated to apply pressure to the panel and break the magnetic attraction between one or both of the panel magnetic foundation member and the magnet or the land magnetic foundation member and the magnet.

Abstract: A magnetic latching system is provided for removably latching a panel to an aircraft surface portion. The latching system includes a removable axis panel engageable to a latching land. The panel and land define opposing magnetically attractive surface portions, with a body of magnetic material disposed there between. An inflatable seal is also disposed intermediate the panel and the land. Upon inflation, the inflatable seal is operative to urge the panel away from the land far enough to reconnect magnetic engagement between the panel and the land, sufficient to permit disengagement of the panel from the land.
