Abstract: A heated floor panel assembly for aircraft includes an impact layer made from a 2-D or 3-D woven high temperature thermoplastic fiber matrix impregnated with a resin. The impact layer can further include woven metallic fibers. The assembly also includes a stack of structural layers, a heating layer, and a core layer for absorbing shear stress.

Abstract: A de-icing assembly for a surface of an aircraft includes: a carcass with a first layer, a second layer, and a carcass centerline and a plurality of seams sewn into the carcass, wherein the plurality of seams join the first and second layers of the carcass together. The assembly includes a plurality of inflation passages formed by the plurality of seams and disposed between the first and second layers of the carcass. The system also includes a manifold fluidly connected to and disposed beneath the carcass, the manifold comprising a width and a manifold centerline oriented approximately perpendicular or parallel to the carcass centerline.

Abstract: An ice protection system may include a blade and an electrothermal heater including a carbon nanotube (CNT) element and a metal element. The CNT element may be a CNT fabric or a CNT yarn. The metal element may be coupled to the CNT element via a metallization process, or the like. The electrothermal heater element may include an electric sheet resistivity between 0.01 and 0.5 ohms/square.

Abstract: Additively manufactured heating elements for tubes are made from a positive temperature coefficient heater ink printed on the tube. A bus bar is likewise printed onto the tube using a conductive ink. The positive temperature coefficient heater ink and bust bar conductive ink are encapsulated with a closing adhesive.

Abstract: A heated floor panel assembly with an impact layer is made to absorb blunt force and protect a heating element inside the assembly. The assembly further includes a plurality of structural layer made of a reinforced polymer matrix, one or more core layer with a honeycomb or foam structure for absorbing shear stress, and a heating layer containing the heating element. The impact layer is a composite layer with a resin impregnated fiber matrix.

Abstract: A hose intervention clamp is provided for clamping a hose/connection nipple assembly, wherein the hose/connection nipple assembly has a hose and a connection nipple having a locking slot. The hose intervention clamp includes a locking ring, an upper clamp portion, and a lower clamp portion pivotally connected to the upper clamp portion. The upper and lower clamp portions are pivotally moveable relative to each other from a first at least partially open position to a second locking position, and in the second locking position the upper and lower clamp portions define a recess for receiving the hose/nipple assembly. The locking ring is configured to be received in the locking slot when the upper and lower clamp portions are in the second locking position. A hose intervention clamp system includes a hose/connection nipple assembly having a hose and a connection nipple having a locking slot, and the described clamp.
