Abstract: An aircraft may include an interior and a deployable liquid cooler. The deployable liquid cooler may include a deployable heat exchanger that may be fluidly coupled to at least one heat source of the aircraft. The deployable liquid cooler may receive a cooling system fluid from the heat source for circulation through the deployable heat exchanger. The deployable heat exchanger may be movable between a stowed position in the aircraft interior and a deployed position outside the aircraft. The deployable heat exchanger may transfer heat of the cooling system fluid to an environment outside of the aircraft when the deployable heat exchanger is in the deployed position.

Abstract: An apparatus and method for wind debris detection comprises a spring loaded probe that is deployed on the leading edge of an aircraft wing into an area where debris formation might impact wing aerodynamic performance. The probe travel is sensed by sensors (angular displacement, linear displacement, proximity, torque, load cell on spring, and the like), and if the sensor(s) detect that probe travel is limited then presence of debris is indicated.

Abstract: A composite stator vane for a gas turbine engine comprising a plurality of compression molded, heat cured plies, the plies including a plurality of centrally located internal plies of reinforcement material of unidirectional yarns of para-aramid fibers, a plurality of plies of resin impregnated graphite fiber material on each side of the centrally located plies of reinforcement material, and an external steel wire mesh ply on the leading edge of the vane.

Abstract: A turbofan engine fan stator assembly includes stator vanes readily insertable through the outer shroud into the stator assembly hub. Elastomeric grommets seal between the vanes, shroud and hub, and an outer band radially inwardly compresses the assembly. The vanes are radially secured to the hub only through frictional engagement with the hub grommet.
