An evacuation system may comprise an inflatable slide, a raft compartment, and an evacuation raft. The evacuation raft may be disposed within the raft compartment. The evacuation raft may be configured to deploy in response to a water landing of an aircraft.

A flotation device that can include a multi-chamber flotation element having an active inflation chamber and a passive inflation chamber. The flotation device can have a first valve in fluid communication with the active inflation chamber but not the passive inflation chamber and an opening in fluid communication with the passive inflation chamber but not the active air chamber. The active inflation chamber can be configured to be inflated through the first valve. The active inflation chamber can be configured to expand the passive inflation chamber from a collapsed state to an expanded state as the active inflation chamber is expanded by, for example and without limitation, permitting ambient air to enter the passive inflation chamber when a pressure within the passive inflation chamber is less than an ambient air pressure.

A liferaft system comprises a container for storing a liferaft, and at least one sheet of material for fitting over an exterior surface of the liferaft container and configured to heat an interior volume of the liferaft container.

An electro-pneumatic valve assembly includes a valve having a valve housing and a poppet and a solenoid valve having an actuator housing and a valve body. The valve housing has a wall that defines a valve inlet that is arranged to receive a fluid flow from a pressurized container and defines a valve outlet and a first port. The poppet is disposed within the valve housing and is movable between a first position and a second position. The actuator housing defines an opening. The valve body has a first wall that defines an inlet that is fluidly connected to the first port and a second wall that defines an outlet that is fluidly connected to the second port.

An evacuation system may comprise a packboard, an evacuation slide configured to deploy from the packboard, and a canopy support apparatus is disclosed. The canopy support apparatus may comprise a valve extending from a proximal end of a canopy support tube toward a distal end of the canopy support tube and into an internal cavity of the canopy support tube. The valve may be configured to open a channel during inflation. The valve may be configured to seal the channel via internal pressure in the internal cavity acting on a sealing component of the valve when the canopy support tube is in an inflated state.

An evacuation slide for an aircraft may be deployable in a slide mode and a raft mode. The evacuation slide includes a head end and a toe end, with the head end having a mounting feature and the toe end being longitudinally opposite the head end. In response to the evacuation slide being in the slide mode, the head end of the evacuation slide is mounted to the aircraft via the mounting feature. In response to the evacuation slide being in the raft mode, the evacuation slide is detached from the aircraft and the mounting feature is a boarding aid, according to various embodiments.

An evacuation slide may comprise an inflatable side rail extending from a head end to a toe end of the evacuation slide. A lifeline-geometric restraint may be coupled to the inflatable side rail. A restraint pin may be coupled to the lifeline-geometric restraint. A first loop may be coupled to a first location on the evacuation slide. A second loop may be coupled to a second location on the evacuation slide. The first loop may be configured to receive the second loop and the second loop may be configured to receive the restraint pin when the evacuation slide is in a folded position. The restraint pin may be configured to translate out the second loop in response to an internal pressure of the evacuation slide exceeding a predetermined internal pressure.

An inflatable slide may comprise a ramp portion and a slide portion extending from the ramp portion. A multipurpose indicator tube may be fluidly coupled to the slide portion. A releasable restraint may be disposed between the multipurpose indicator tube and the slide portion. The releasable restraint may comprise a first restraint portion coupled to an end of the multipurpose indicator tube and a second restraint portion coupled to a toe end of the slide portion. The first restraint portion may be releasably coupled to the second restraint portion. A detachable restraint may be coupled to the slide portion and configured to detachably couple to the end of the multipurpose indicator tube.

An inflatable motor boat refers to water vehicles, in particular, to inflatable boats with outboard engines operating in low water conditions. The problem to which the invention is directed, is to improve the performance parameters of inflatable motor boats, The technical result of the claimed invention is the possibility of high-performance boating in low and extreme low depth conditions at different speeds due to the presence of the inclined longitudinal tunnel, with some configuring details in different versions, which allows to improve the water supply to the propellers of outboard engines or, in the case of water jet engines, to their water jet inlets, to optimize their location and eliminate the risk of damage thereof. The claimed technical result is achieved by the fact that the invention is an inflatable motor boat with a U-shaped hull in plan view. The hull of the inflatable motor boat is formed by open outline of inflatable boards and bow part. An inflatable bottom is attached to the hull, which bottom is divided into at least three longitudinal segments. A longitudinal tunnel is made in the middle segment of the bottom, the inner surface of which tunnel has essentially arc-shaped form. The tunnel comprises a portion having a wedge-shaped form in a vertical section, wherein the angle of inclination of the portion relative to the water surface plane is from 5 to 45. The tunnel can also comprise an additional portion with an angle of inclination from 0 to 20 relative to the water surface plane, wherein the length of the additional portion is less than the length of the wedge-shaped portion.

A life raft may include a base comprising a first side and a second side, and a self-supporting, collapsible spring canopy. The canopy may include a spring wire frame, a first panel circumscribed by the spring wire frame, and a second panel circumscribed by the spring wire frame.
