One version of that foam material is used on the Learjet model 31 around the outside of the fuselage fuel cell. The theory is that it is highly absorbent and will slow the run-off and inhibit vaporization to add a few seconds to a passenger's time to get out in a crash. We have considered using it on other Learjet models...but it is quite costly for the effect it offers. On the model 45, we have twin wall fuel cell to accomplish the same level of safety. The people who market the stuff cite other design usage...for example, they sell various grades in varied porosities...that are intended to be installed inside the fuel cell to prevent sloshing and slow the rupture flow. I think the A-10 warthog uses this. Perhaps it helped the A-10 earn its reputation as a tough bird.Terry B________________________________________________________________________________
