In this phase I proposal GTL will leverage its experience in innovative composite tank design and production for spacecraft and propulsion systems in order to produce a high-performance composite torpedo fuel tank. GTLs methods reduce tank mass by 60-75% over the state-of-the-art rocket systems. These rocket propellant tanks operate with corrosive fuels in harsh environments, have metal-to-composite structural interfaces, and are structurally load bearing. Fluid management and utilization are also critical in propulsion systems. GTLs experiences and existing solutions will be applied to produce the MK48 replacement fuel tank.
Benefit: The composite fuel tank designed in this phase I effort and produced in the phase II effort would provide the Navy with a MK48 torpedo fuel tank that is far lower in mass, requires less maintenance and replacements, reduces or eliminates corrosion, interfaces with the existing metal structure, and increases fuel volume and utilization. The reduction in tank mass allows for increased fuel loading, and/or the addition of new systems such as sensors. The increased fuel loading and utilization will increase the operational capabilities of the torpedo. The reduction in maintenance and replacement will reduce costs and down time.
