Fuel Bladder Cell

[santicanglada]

Hello, i need some help with the FUEL TANK we are designing.

We are planning on making a BLADDER CELL from ATL, for this reason, the tank is made out of a flexible material. As the rules says:

"IC2.4.3 Any fuel tank that is made from a flexible material, for example a bladder fuel cell or a bag tank, must
be enclosed within a rigid fuel tank container which is securely attached to the vehicle structure. Fuel
tank containers (containing a bladder fuel cell or bag tank) may be load carrying."


In our case, the cell will be enclosed in a compartiment on the back of the driver's seat (separeted by a firewall). This compartiment,
is quiet big, and the fuell cell will be enclosed inside. This tank, is not going to occupy all of the space inside the compartiment, so my
question is: Do we have to make another "rigid fuel tank container" inside that compartiment? Or does the compartiment count as a rigid
fuel tank container??

This is more or less how it is going to look like, mind that the side walls are taken out (made of carbon fiber) and the firewall cut in half
in this view (blue box on top of tank):

First of all once more the advice that on this forum you can get only unofficial opinions. To get a definite answer you have to send your question to the rules commitee of the competition you are planning to take part at.

In this case I'd say the important thing is that the whole structure around the bladder is rigid and fluid prove.
