摘要： 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.

摘要： A liquid containment cell includes an inner layer configured to contain a liquid, an outer layer, and a multilayer self-sealing structure disposed between the inner layer and the outer layer, where the multilayer self-sealing structure includes a plurality of sealing liner layers and further includes at least one slip layer disposed between adjacent sealing liner layers of the plurality of sealing liner layers. The at least one slip layer includes a polyethylene (PE) material, and the at least one slip layer is configured to permit at least one sealing liner layer of the plurality of sealing liner layers to move at least partially into a hole created by a projectile.

摘要： A modular powered air purifying respirator (PAPR) is provided including one or more of a first inlet configured to receive an ambient gas; a gas filter in fluid communication with the first inlet and configured to filter the ambient gas; a blower configured to boost at least one of a flow rate or a pressure of the ambient gas entering and/or exiting the gas filter; a second and independent inlet configured to receive a non-ambient gas; a first outlet configured to selectively provide a breathing gas to a user from the ambient gas or the non-ambient gas; and/or a controller and switching device configured to select the source of the breathing gas between the first inlet and the second inlet. Embodiments may also include a power source for the blower.

摘要： A fuel cell includes a flexible body and first and second fittings attached to the flexible body. The first and second fittings each include a first opening configured for ingress or egress of a fluid, and each include second openings extending through outer portions of the first and second fittings. The first and second fittings are more rigid than the flexible body. The fuel cell further includes a first elongated interconnect attached to the first fitting through one or more of the second openings extending through the outer portion of the first fitting and connected to the second fitting through one or more of the second openings extending through the outer portion of the second fitting such that the first elongated interconnect couples together the first and second fittings.

摘要： 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.

摘要： A filter housing for use with a protective mask or other personal protective equipment is described including a base, a top, a sidewall connecting the top and the base, and a void that houses a filter medium or a filter medium cannister. The housing also includes an inlet with an inlet opening for receiving ambient gas into the container, an outlet including an outlet opening for discharging gas from the container to the protective mask, and an interface for removably securing the filter housing to the protective mask or other personal protective equipment. The base may include a concave surface substantially surrounding the opening and the interface, and a space between the void and the concave surface of the base may be partitioned by a plurality of members connected at least partially to the base or the sidewall and define a substantially planar surface facing the void.
