Abstract
A plug type door intended particularly for use on a military cargo type aircraft is designed to enable its ejection if necessary. To do this, an operating device such as a handle (28) simultaneously controls retraction of hinge pins (16c) from the hinges about which the panel (10) of the door is hinged to its frame (12) and retraction of the mechanical elements (21) against which the stops (19) fitted on the panel usually bear by gravity, when the door is closed. Furthermore, guide ramps connected to the frame (12) and in which the rollers supported by the panel (10) open downwards, to enable the panel (10) to drop by gravity when the handle (28) is pulled.
Claims9
Aircraft door comprising a frame that can be fixed to the fuselage of the aircraft, a panel articulated onto the frame by articulation means, stops and mechanical elements installed on the panel and on the frame respectively, so as to remain in mutual contact under the effect of the weight of the panel when the door is closed, and guide means inserted between the panel and the frame in order to automatically release/engage the stops with respect to the mechanical elements, at the beginning of opening and at the end of closing of the door respectively, in which the said door also comprises ejection triggering means, that can control mechanical disconnection of the articulation means and a relative disengagement of the stops from the mechanical elements, the guide means enabling downwards displacement of the panel by gravity when the ejection triggering means are used.
