In Phase I, JBE proved that two coatings improved the abrasion resistance of materials typically used in high temperature seals. Phase I testing was done at ambient temperature. In Phase II, JBE will determine the optimal seal material and coating combinations, work to optimize the coating processes, and validate the improved abrasion resistance at representative and relevant temperatures.
Potential NASA applications include reusable space vehicles such as Commercial Resupply Services (CRS) and Commercial Crew Integrated Capability (CCiCap) as well as high-speed propulsion systems.
An improved high temperature seal will be of immediate benefit to the expanding hypersonics market by providing increased capability, reliability, and reduced cost. The target market is DOD airbreathing hypersonic products such as the HAWC, TBG, CPS, and reusable ISR platforms and hypersonic delivery vehicles.
