Tank Construction
The BATT is a pillow-shaped, collapsible, double-walled fabric container equipped with a number of
internal liquid stabilizing elements (baffles), an external built-in harness as well as fill, drain and vent
fittings and lifting handles.
Structurally, the BATT consists of outer and inner bladders. The outer bladder provides secondary
containment and protection for the inner bladder from abrasion. It has a built-in strapping system that
enables the BATT to ensure a secure fit onto an aircraft cargo deck at various filled capacities. Each
adjustable strap includes a tensioning device (ratchet buckle) and snap-hooks. The straps are connected to
the tank through steel-forged D-rings and special fabric mounting points on the outer tank. Straps can easily
be replaced in case of damage. The outer tank has a leak-proof, fuel-resistant liquid-tight zipper that can be
opened to allow inspection of the inner tank for leaks or damage.
The inner bladder provides containment for transported fuel. It has built-in liquid stabilizing and bladder
restraining elements with wall-like structures (baffles) to reduce fluid surge. Inner and outer bladders are
interconnected by built-in handles aligned face-to-face, between the inner and outer bladders and the outside
lifting handles, and by NPT threaded flanges which clamp inner and outer bladders.
The BATT is rated to its maximum volume. The BATT bladder and harness rating is based on sg = 0.85 of
the transported liquid. If the specific gravity of the liquid you are transporting is heavier, you must decrease
the capacity of your tank.
Each BATT has its own serial number (punched on top of the NPT threaded flanges) and is marked with its
authorized fuel type, wet date, fill height, maximum capacity and dry weight.
