Fuel Tank Reinforcement
A possible solution to help prevent a fire.

Observations of several model crashes, both jet and propellor driven, where the energy exchange was severe, revealed the devastating effect on the fuel tanks.
Since fluids are non compressible, the hydraulic effect of the collapsing fuel tank forces the fuel to burst through the walls of the tanks resulting in atomization. This sets the stage for a fire if there is an ignition source present, such as a red hot engine.
Any effort to contain the burst is an effort to prevent a fire. Model fuel tanks like the blow molded polyethylene units from Sullivan or Du-Bro are very convenient to use and very low priced. Some are much stronger (thicker walls) than others and are more appropriate for use in turbine models.
BVM uses the Sullivan BT-16, R-12 and the R-16 as auxiliary or header tanks along with our aluminum fuel cap fittings.
To further increase the burst resistance of these units we are suggesting to apply the extreme tensile and tear resistant strength of Kevlar strands for reinforcements to these kinds of tanks.

Three wraps length wise will help retain the cap and two wraps in three places along the length of the tank will help contain the tank's side walls.
This presentation is a concept only. Perhaps some laboratory testing could be pursued. A proposal for such is being made to the AMA safety council.
The advantages of the system shown are light weight, low cost and the fuel contents remain visible. The effectiveness is yet to be determined.
