Abstract: The present disclosure provides a method for coating a composite structure, comprising forming a first slurry by combining a first pre-slurry composition comprising a first phosphate glass composition, with a primary flow modifier and a first carrier fluid, wherein the primary flow modifier comprises at least one of cellulose or calcium silicate; applying the first slurry on a surface of the composite structure to form a base layer; and heating the composite structure to a temperature sufficient to adhere the base layer to the composite structure.

Abstract: A releasable restraint for an inflatable slide is disclosed, in accordance with various embodiments. The releasable restraint may comprise a first mating portion having a receptacle. The releasable restraint may comprise a second mating portion having a protrusion. The protrusion may be configured to fit within the receptacle. An adjustment fastener may be coupled to the receptacle and configured to adjust a coupling strength of the releasable restraint.

Abstract: An electro-thermal ice protection system for an airfoil comprises: a metal foil heater including an integral parting strip, the metal foil heater configurable to cover at least a portion of a leading edge of the airfoil with the integral parting strip disposed along an air-stagnation zone of the leading edge; and a controller coupled electrically to the metal foil heater for controlling electrical energy from a power source to the metal foil of the heater in accordance with a pulse duty-cycle and for controlling power to the parting strip of the heater to maintain the air-stagnation zone virtually free of ice formation.

Abstract: An inflatable evacuation slide includes a feature to ensure against buckling of the sliding surface under load. In one embodiment, the slide is made from a fabric sliding surface stretched between two lateral side rail tubes. The lateral side rail tubes are supported by a plurality of transverse tubes and transverse trusses such that the side rail tubes maintain the sliding surface in a taut condition suitable for use as a slide. The foot end of the slide includes an additional longitudinal tube extending from the toe end partway toward the head end of the slide. This toe end longitudinal tube acts as a pneumatic spring to support a sliding passenger as he or she reaches the extreme toe end of the evacuation slide.
