  • Stay sharp, fail safe leading edge configuration for hypersonic and space access vehicles
    Patent number: 8844877
    Abstract: A passive non-ablating thermally protective structure body is disclosed. An improved-reliability heat pipe edge comprises a non-porous material formed into a wedge-shaped chamber, and a porous layer. The porous layer extends from interior surfaces of the non-porous material to provide capillary wicking.
