A supervision system for an aircraft for monitoring a safe charging of portable electrical devices of a passenger who may be in an attentive or an inattentive state, comprising a passenger seat, a power supply station assigned to the seat and used to supply electrical power to the portable electrical device, the portable electrical device being connected to the power supply station, a camera, which detects the state of the passenger situated on the seat, and an arrangement to distinguish whether the passenger is in an attentive or inattentive state. A method for safe charging of portable electrical devices is also presented and described, comprising the steps of detecting a passenger with a camera, analyzing whether the passenger is in an attentive state or in an inattentive state, and, if the passenger is in an attentive state, supplying a power supply station with electrical power to be provided to a portable electrical device connected to the power supply station.

A passenger cabin monitoring system includes infrared cameras disposed in respective passenger rest compartments, a flight attendant information system including at least one display and at least one speaker, and a computing device in communication with the infrared cameras and the flight attendant information system. The computing device is configured to detect a temperature of a portion of passenger rest compartment based on one or more thermal images generated by a respective infrared camera of the passenger rest compartment. The computing device is further configured to compare the temperature of the portion of the passenger rest compartment with a predetermined critical temperature and provide an audible alert and/or a visual alert via the flight attendant information system to indicate a critical status of the passenger rest compartment when the temperature of the portion of the passenger rest compartment is above the predetermined critical temperature.

A multilayer thermoformable film to protect the surface of a workpiece includes an underlayer having first and second faces. The underlayer is made from an adhesive material configured to adhere to the surface of the workpiece by the first face. At least one layer of polymer material is attached to the second face of the adhesive underlayer. The layer of polymer material is resistant to erosion by solid particles and to erosion by liquid particles. It is formed from a polymer material chosen from a polyurethane, a polyether ether ketone and a polyethylene having a very high molecular weight, with a Shore D hardness of between 50 and 65 D. A method of surface protection of the workpiece includes thermoforming the film in a shape adapted to match the shape of at least a portion of the workpiece and applying the film thermoformed onto the surface of the workpiece.

A fire seal end cap including a cap portion and a plug portion, wherein the plug portion protrudes from the cap portion, and wherein the cap portion and the plug portion are formed from a fire-resistant material.

A blade de-icing system for a blade to be de-iced that has a body extending between a leading edge and a trailing edge, said leading edge ending at an apex. The system includes a de-icer component having a recess formed therein and being positioned on said leading edge of said blade so that said de-icer component covers and extends away from said apex and so that said recess is positioned at said apex of said leading edge; and an anti-erosion strip provided in said recess of said de-icer component; wherein said anti-erosion strip and said recess are sized and shaped such that said anti-erosion strip fits within said recess so that outer surface of said anti-erosion strip is flush with the outer surface of said de-icer component. A method of manufacturing the same is also described herein.

Aspects of the present disclosure present floor panels and floor panel assemblies that include incorporated burnthrough resistant materials and/or include burnthrough resistant layers applied to floor panels used in floor panel assemblies, along with methods for inhibiting fire penetration into compartments and methods of making and installing burnthrough resistant floor panels and floor assemblies including such apparatuses and methods as they relate to vehicles, including aircraft.

A device for suppressing and/or extinguishing a fire associated with a container may include a housing defining a hollow sleeve and a column configured to be received within the hollow sleeve. The column may define a first chamber, a second chamber, at least one aperture, and a piercing end configured to pierce a barrier. The first chamber may be configured to receive an expansion agent, and the second chamber may be configured to receive a fire extinguishing agent. The device may be configured such that upon activation of the expansion agent, the column extends from the housing so as to enable the piercing end to penetrate the container and to enable the fire extinguishing agent to be delivered into an interior of the container via the at least one aperture.

An engine pylon that is used for supporting an engine, the engine pylon including a pylon body having an upper pylon and a lower pylon. The pylon further includes a fairing that covers the pylon body such that the upper pylon and fairing define a predetermined region. Moreover, the pylon includes a first drain that is configured to discharge a flammable liquid leaking from a pipe provided within the predetermined region into outside air; and a ventilation path configured to bring the inside of the predetermined region into communication with the outside air. The first drain includes a drain port and a drain pipe, wherein the drain pipe extends in a rear direction from the drain port and has an outlet at a rear end of the drain pipe, the outlet being located past a rear end of the upper pylon and a rear end of the lower pylon.

A gas turbine engine has a nacelle providing an external skin of the engine, a casing structure radially inwards of the external skin and providing an outer surface of an air flow duct of the engine, and plural engine components located in the bay formed between the casing structure and the nacelle. The components are part of either a first set of components or a second set of components. The components of the first set are all the components from the bay which are potential ignition sources, and the components of the second set are all the remaining components from the bay. The engine further has a container located in the bay, the container being fireproof capable of withstanding the application of heat by a standard flame for 15 minutes and the container containing the components of the first set.

A support arrangement include a mount, a cover, and a metallic mesh body. The mount has a base portion and a mount clamping portion. The cover has a plate portion and a cover clamping portion, the cover fixed to the base portion of the mount and the cover clamping portion registered to the mount clamping portion. The metallic mesh body is arranged between the mount clamping portion and the cover clamping portion to compressively support a sensor element between the mount clamping portion and the cover clamping portion. Fire and overheat detection systems, gas turbine engines with fire and overheat detection systems, and methods of making support arrangements for fire and overheat detection systems are also described.
