A collapsible fuel cell for an aircraft includes an inner textile support substrate having an outer surface including one or more textile crease lines forming a fold pattern and an outer shell layer conforming to the outer surface of the textile support substrate to form the fuel cell. The fuel cell is collapsible along the fold pattern formed by the one or more textile crease lines.

Collapsible fuel cells for aircraft

In an embodiment, an aircraft includes a fuselage; a propulsion system powered by a fuel; and a fuel cell configured to store the fuel, the fuel cell including an inner layer configured to contact the fuel; an outer layer; and a self-sealing fabric structure formed from ultra-high molecular weight polyethylene (UHMWPE), the self-sealing fabric structure being between the inner layer and the outer layer, the self-sealing fabric structure being configured to self-seal a hole formed in the inner layer and the outer layer by a projectile.

Aircraft fuel tanks including self-sealing fabric

A fuel cell containing fuel for an aircraft includes an innermost layer configured to contact the fuel, an outermost layer and a containment gel formed from isocyanate and polyol interposed between the innermost and outermost layers. The containment gel is configured to self-seal a ballistically formed hole therein, thereby reducing leakage of the fuel from the fuel cell.

Self-healing containment gels for aircraft fuel cells

In certain embodiments, a hose includes an inner tube, a filler material, and an outer cover. The inner tube has a cross-sectional shape and includes a cavity for transporting a substance. The filler material is provided around an outer periphery of the inner tube. The filler material includes a self-sealing material or a self-healing material. The outer cover is provided around an outer periphery of the filler material such that the filler material is between the outer cover and the inner tube. The outer cover has a D-shaped cross-sectional shape.

Multilayer hose and associated method

A method of fabricating a tank includes connecting a pressure source to a nozzle on a male mold, inflating the male mold via the nozzle, forming a tank by applying at least one layer over the outer surface of the male mold, the tank having a port formed about the nozzle, deflating the male mold, and withdrawing the male mold through the port. A method of fabricating a tank includes 3D-printing a male mold, connecting a pressure source to a nozzle on the male mold, inflating the male mold via the nozzle, forming a tank by applying at least one layer over the outer surface of the male mold, the tank having a port formed about the nozzle, deflating the male mold, and withdrawing the male mold through the port. A method of fabricating a tank includes forming a tank on a mold formed from a foam blocks.

Method of manufacturing complex-shaped, flexible, and reusable tanks

An explosion suppression insert for a fuel tank includes a hollow body having an inner surface and an outer surface, the hollow body being made of an explosion suppressing material; and a plurality of perforations defined in the outer wall. In some embodiments, a nonwoven explosion resisting insert for a fuel tank includes a body including a plurality of interconnected non-woven fibrous struts being made of an explosion suppressing material, the body having a first end and a second end; and a plurality of voids defined by the plurality of struts, the voids being configured such that the body has a porosity of between 5 pores per inch and 50 pores per inch. Methods of manufacturing explosion resisting inserts are also provided.

Process of manufacturing reticulated foam products, using alternative materials

In an embodiment, a fuel cell includes: a flexible substrate including a first fuel-tolerant material; a fitting on the flexible substrate, the fitting including first openings extending through an outer portion of the fitting; a primer coating on the outer portion of the fitting, the primer coating including a second fuel-tolerant material; first yarns strung through the first openings of the fitting, the first yarns stitched into the flexible substrate; and an encapsulant encapsulating the first yarns, the primer coating, and the outer portion of the fitting, the encapsulant disposed on the flexible substrate, the encapsulant including a third fuel-tolerant material, the third fuel-tolerant material chemically bonded to the second fuel-tolerant material and the first fuel-tolerant material.

Fuel cell and method of forming the same

A method of manufacturing a seamless, non-wicking containment bladder includes providing yarn materials, coating the yarn materials with a precursor protective coating, loading the yarn materials into an additive manufacturing process, depositing the yarn materials in pre-selected amounts and locations to form a desired structure, forming and heat-setting, and coating the seamless bladder.

Method of manufacturing containment bladders

An impact resistant membrane and methods of preparing and utilizing the membrane are disclosed. The membrane comprises a loft layer, a first polymeric layer bonded to a first surface of the loft layer, and a second polymeric layer bonded to a second surface of the loft layer. The membrane can be fabricated by providing a loft layer and applying a polymeric layer on a first surface and on a second surface of the loft layer. The membrane has a higher resistance to failure due to impact and thus protects the underlying structure membrane for a longer time. A method of facilitating protecting a structure comprises providing a single ply membrane having a loft layer and a polymeric layer disposed on at least two surfaces of the loft layer.

Roofing membranes

A composition having a polyurethane, a hydrophilic polyisocyanate, a wetting agent, and a fluoropolymeric additive can be disposed on a substrate such as a fabric to provide water-repellant characteristics. The urethane-coated substrate can then be fabricated into a water storage container.
