Abstract

An antiexplosion coiled aluminum foil mesh for the fuel oil tank of airplane is made up of the aluminum foil with cellular meshes through coiling. Its length Y=W / n, where W is the width of fuel oil tank and n is a positive integer.

Description

technical field [0001] The invention belongs to the explosion-proof technology of aircraft, and relates to a method for manufacturing an explosion-proof aluminum foil mesh roll of an aircraft fuel tank. Background technique [0002] At present, the explosion-proof materials of aircraft fuel tanks use polyurethane foam, which has a short lifespan and easily pollutes the fuel tank. There have been research documents abroad on the use of aluminum foil mesh as an explosion-proof material for aircraft fuel tanks ("Evaluation of EXPLOSAFE explosion-suppressing materials on the protection of aircraft fuel tanks" ADA093125 / AFWAL-TR-80-2043), which mentioned the use of planes for aircraft fuel tanks And the anti-explosion idea of ​​rolled aluminum foil mesh, but its structural parameters and manufacturing methods are not described in detail. At present, no literature has been retrieved on the actual use of explosion-proof aluminum foil mesh in aircraft fuel tanks. Contents of the ...
