Abstract: A sea anchor includes a textile tube and a resiliently flexible support. The textile tube may include a first end and a second end. The first end may have a rim defining a mouth and the second end may be closed. In various embodiments, the resiliently flexible support is coupled to the first end of the textile tube. The resiliently flexible support, in response to the sea anchor being deployed, may be configured to expand the mouth and retain the mouth open. In various embodiments, the textile tube has a conical shape, with the mouth of the first end being a base of the conical shape and the second end being a point of the conical shape. The resiliently flexible support is a ring coupled to the rim of the first end of the textile tube, according to various embodiments.

Abstract: A restraint may include a longitudinal body having a first end and a second end. The restraint may also include a plurality of engagement features distributed between the first end and the second end. A dimension of at least one of the longitudinal body and the plurality of engagement features may vary along at least a portion of a length of the longitudinal body. The restraint may further include a head disposed at the first end of the longitudinal body. The head may define an aperture and may include a pawl that configured to individually engage the plurality of engagement features. The dimension may vary incrementally or continuously along at least the portion of the length of the longitudinal body from the first end to the second end.

Abstract: A life raft includes a base and an inflatable canopy. The base has a first side and a second side and the inflatable canopy is coupled to the first side of the base and configured to inflate and extend across the first side of the base to form a first chamber defined between the first side of the base and the inflatable canopy. The inflatable canopy is configured to inflate in response to deploying the life raft. Inflation of the inflatable canopy enables the life raft to self-right. In various embodiments, the base includes an inflatable border tube defining a first inflatable volume. The inflatable canopy may define a second inflatable volume and the first inflatable volume may be in fluidic communication with the second inflatable volume.

Abstract: An evacuation assembly of an aircraft includes an evacuation slide and a sheet coupled to the evacuation slide. The sheet may be deployable in a wind curtain configuration and a canopy configuration. In the wind curtain configuration, the sheet may extend, as a substantially vertical panel, longitudinally along opposing lateral sides of the evacuation slide. In the canopy configuration the sheet may extend over at least a portion of a top side of the evacuation slide. In the canopy configuration, the sheet may include a first portion that is the substantially vertical panel that extends longitudinally along the opposing lateral sides of the evacuation slide and a second portion that extends over the top side of the evacuation slide. The second portion of the curtain may in a furled, collapsed form in the wind curtain configuration and may be configured to unfurl in the canopy configuration.

Abstract: An evacuation assembly of an aircraft may include an evacuation slide and a sheet coupled to the evacuation slide. The sheet may be deployable in a negative lift configuration and a canopy configuration. In the negative lift configuration, the sheet may extend across at least a portion of an underside of the evacuation slide. In the canopy configuration, the sheet may extend over at least a portion of a top side of the evacuation slide. The evacuation assembly may also include a support that is coupled to and extends between the top side of the evacuation slide and the sheet in response to the sheet being in the canopy configuration.

Abstract: An aspirator may include an aspirator body that defines an annular cavity, a central channel, and an annular slit. Fluid communication between the annular cavity and the central channel may be via the annular slit. The aspirator body may include an entrainment opening through which ambient air is configured to be entrained into the central channel in response to gas flowing from the annular cavity through the annular slit and into the central channel.

Abstract: An aspirator includes an aspirator body having at least one flapper door designed to allow intake of a gas from an environment of the aspirator. The aspirator also includes an aspirator barrel having an end tip, a compressible spring, and a fabric positioned about the compressible spring, and designed to extend in response to receiving the gas and to transfer the gas from the aspirator body to the inflatable flotation device. The aspirator also includes a gas valve designed to receive a fluid from a compressed fluid source. The aspirator also includes a nozzle positioned within the aspirator body, coupled to the gas valve, and designed to receive the fluid via the gas valve and to direct at least a portion of the fluid towards the aspirator barrel such that the at least one flapper door allows the gas to flow from the environment into the aspirator barrel.
