Back Ballistically Tolerant Fuel Hose

“Proposed Effort: The Naval Postgraduate School will develop a self-sealing fuel hose capable of immediate closure of both incident and exit holes from an incident projectile having a diameter up to 0.50 caliber at an impact velocity of 1600 FPS. The self-sealing hose will meet all geometric requirements previously specified in the description. A key advantage to a self-sealing hose is the ability to de-couple the incident momentum of the projectile preventing additional stress on the fuel supply system by allowing the projectile to completely penetrate the hose with minimal resistance.
The proposed solution will enable continued operation of the ballistically tolerant fuel hose after taking an impact from the identified projectile. Many of the current self-sealing materials tested have exhibited little to no degradation when exposed to fossil fuels for periods greater than 5 years (currently 7 yrs) enabling mission completion despite a direct projectile impact (up to 0.50 caliber) with the self-sealing fuel hose.
This effort will incorporate specific polymers that have previously exhibited the “snap back” effect. Previous efforts have demonstrated the self-sealing capability for fluid viscosities near water at up to 100 psi internal pressure and extreme temperatures from – 35℉ up to 135℉.”
