Thermal protection close-outs are disclosed. A disclosed example thermal protection close-out includes a ring defining an aperture extending therethrough, an outer layer of the ring including a fabric sleeving, and an inner layer of the ring including insulation, the outer layer enclosing the inner layer.

Thermal protection close-outs

A fuel cell stack is described. The fuel cell stack comprises an interconnect assembly comprising a cathode-side interface coupled to an interconnect via a first joint, and an anode-side interface coupled to the interconnect via a second joint, the interconnect assembly having a first coefficient of thermal expansion (CTE) at an interface side of the interconnect assembly. The fuel cell stack further comprises a fuel cell element coupled to the interconnect assembly at the interface side via a hermetic seal, the fuel cell element having a second CTE at the interface side, the first CTE and the second CTE satisfying a predetermined CTE matching condition.

Fuel cell interconnect assembly

A mechanically attached thermal protection system (MATPS) includes an insulating tile having a top surface, a bottom surface, and a plurality of access holes that extend through the insulating tile from the top surface to the bottom surface. A plurality of brackets include a first end attached to the insulating tile and a second end including a mounting hole therethrough, the second end being positioned proximate the bottom surface of the insulating tile. A plurality of fasteners are positioned proximate the bottom surface of the insulating tile and at least partially positioned within one of the access holes so as to be accessible from the top surface of the insulating tile through one of the plurality of access holes. A MATPS including a plurality of air channels within the insulating tile and a method for sealing these air channels to those within an adjacent structure is also described herein.

Mechanically attached thermal protection system

A reinforcing fiber for reinforcing a transparent matrix composite. The fiber includes a substantially transparent fiber ribbon having an elongated cross-sectional geometry. The fiber ribbon includes edges that are substantially opaque. Light is substantially prevented from passing through the opaque edges to reduce or eliminate light distortion through the fiber. A composite utilizing the reinforcing fibers and a method for making a window assembly and a method for manufacturing a vehicle are also disclosed.

Distortion resistant transparent reinforcing fibers for use in transparent reinforced composites

High-temperature fabrics with a coatings to provide oxidation protection at high temperatures, and capable of being formed into a variety of softgoods parts, and methods for their manufacture are disclosed.

Re-usable high-temperature resistant softgoods for aerospace applications

A glass fiber and a method of manufacturing a glass fiber for reinforcing a transparent composite matrix is disclosed. The glass fiber includes a first glass material having a first refractive index, a first modulus, and a first durability characteristic and a second glass material having a second refractive index, a second modulus, and second durability characteristic. The second durability characteristic is greater than the first durability characteristic. Durability characteristic is selected from the group comprising resistance to chemical attack, resistance to acid attack, resistance to fading from exposure to ultra-violet radiation, and resistance to mechanical abrasion.

Glass fibers having improved durability

A glass fiber and a method of manufacturing a glass fiber for reinforcing a transparent composite matrix are disclosed. The glass fiber includes a first glass material having a first set of mechanical properties including a first modulus and a first coefficient of thermal expansion (CTE) and a second glass material having a second set of mechanical properties including a second modulus and a second CTE. The second glass material forms a substantially uniform coating on the first glass material. The second CTE is less than the first CTE. The glass fiber is formed by reducing the cross-section of a glass fiber preform of the first glass material coated with the second glass material by hot working. Because of the selected difference in the CTE's, the first glass material imparts a compressive force upon the second glass material, which improves the strength of the glass fiber.
