Abstract
Abstract A device is needed to rapidly suppress gasoline fuel fires which are star as a result of the rupture of military vehicle fuel tanks by armor-piercing projectiles. The present invention contemplates a fuel fire suppressing device in the form of two hollow panels pressurized with a fire suppressant substance, such as Halon 1301; the panels are located in the path that an enemy projectile would take during passage through the fuel tank. The opening formed in each panel by the projectile permits automatic discharge of the pressurized suppressant onto the fuel escaping from the tank.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
93 words
In a military vehicle, equipped with a rectangular fuel tank having two generally parallel major walls: the improvement comprising means to suppress fuel fires initiated as a result of fuel tank rupture by armor-piercing projectiles; said fire suppressing means comprising two hollow panels located in near adjacency to the major walls of the fuel tank in the path that an enemy projectile would take during transverse passage through the tank walls, and pressurized suppressant within the panels for automatic discharge to the ambient atmosphere through openings formed in the panel by the projectile.
