Abstract
What is described is a locally yielding structure () with high energy absorption for aeronautical applications, the said structure being substantially closed and substantially rigid, characterized in that at least one wall () of the said substantially closed structure comprises at least one vent valve () which can be opened when a pressure exceeding a predetermined value is present within the substantially closed structure (). In a particularly advantageous application, the invention is used in connection with a helicopter tank and enables the subfloor to be used to absorb energy by being deformed during any impact on the ground. The present invention is also advantageous for limiting the damage caused by explosions in an aircraft fuselage.
