Abstract: Solenoid-operated pressure-regulator modules, aircraft inflatable slide assemblies, and methods for assembling solenoid-operated pressure-regulator modules are described. The solenoid-operated pressure-regulator modules include a primary inflation valve, a secondary inflation valve, a secondary valve actuator, a solenoid, an inflatable slide, and a gas source. The solenoid-operated pressure-regulator modules are configured to selectively enable a fluid connection between a gas source and an inflatable slide to enable inflation of the inflatable slide. The primary inflation valve includes a main cavity, a command cavity, an inlet through which a gas enters the main cavity, an outlet, a poppet that controls a gas flow from the inlet to the outlet, and a valve divider separating the main cavity from the command cavity. The secondary inflation valve is fluidly coupled to the outlet of the primary inflation valve.

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.
