    摘要: A hybrid insulation material comprises of porous ceramic substrate material impregnated with nanoporous material and method of making the same is the topic of this invention. The porous substrate material has bulk density ranging from 6 to 20 lb/ft3 and is composed of about 60 to 80 wt % silica (SiO2) 20 to 40 wt % alumina (Al2O3) fibers, and with about 0.1 to 1.0 wt % boron-containing constituent as the sintering agent. The nanoporous material has density ranging from 1.0 to 10 lb/ft3 and is either fully or partially impregnated into the substrate to block the pores, resulting in substantial reduction in conduction via radiation and convention. The nanoporous material used to impregnate the fiber substrate is preferably formed from a precursor of alkoxysilane, alcohol, water, and an acid or base catalyst for silica aerogels, and from a precursor of aluminum alkoxide, alcohol, water, and an acid or base catalyst for alumina aerogels.

    摘要: A thermal protection system for a vehicle may include a substantially rigid, relatively thin outer aeroshell, a relatively low density insulation layer, and a resiliently compressible conformal layer. The vehicle may include a substructure. The aeroshell may be configured to be fastened to the substructure. The insulation layer may be disposed against the aeroshell. The conformal layer may be disposable against the insulation layer. The conformal layer may be compressively preloaded against the substructure when the aeroshell is fastened to the substructure.

    摘要: A porous ceramic fiber insulating material and method of making a material having a combination of silica (SiO2) and alumina (Al2O3) fibers, and boron-containing powders is the topic of the new invention. The insulative material is composed of about 60 wt % to about 80 wt % silica fibers, about 20 wt % to about 40 wt % alumina fibers, and about 0.1 wt % to about 1.0 wt % boron-containing powders. A specific boron-containing powder used for this invention is boron carbide powder which provide boron-containing by-products, which aid in fusion and sintering of the silica and alumina fibers. The material is produced by forming an aqueous slurry, blending and chopping the fibers via a shear mixer, orienting the fibers in the in-plane direction, draining water from the fibers, pressing the fibers into a billet, heating the fibers to remove residual water, and firing the billet to fuse the fibers of the material. After sintering, bulk density of the new insulation material ranges from 6 to 20 lb/ft3.

    摘要: A leading edge component for reducing drag and improving heat sink properties of an air foil. The leading edge component includes a composite tile component with a predetermined aerodynamic shape and a metallic lip portion with high thermal conductivity. The metallic lip portion is secured to a forwardmost edge portion of the composite tile component to thereby form a leading edge of the air foil. The leading edge component is better able to withstand the structural stresses and extremely high temperatures that result while travelling at hypersonic speeds, without a significant increase in weight to the air foil with which the leading edge component is used.
