Abstract: An aircraft wing with a wing structure and a spoiler movable between a stowed configuration and a deployed configuration are disclosed. The spoiler includes an actuator configurable between an engaged mode and a disengaged mode. When the actuator is in the engaged mode, the actuator can restrict movement of the spoiler and move the spoiler between the stowed configuration and deployed configuration. In the disengaged mode, the actuator allows free movement of the spoiler, such that the spoiler may pop up due to reduced air pressure on the aircraft wing.

Abstract: A vortex generator, includes a vane, mountable on an aerodynamic surface of an aircraft, and an actuator that rotates the vane between a stowed position and a deployed position. The actuator includes a linear actuator, composed at least in part of a shape memory alloy (SMA), that when thermally activated facilitates rotation of the vane between the stowed position to the deployed position. Thermal activation of the SMA is caused via one or more of joule heating, conduction, and induction in response to one or more of an electronic command signal and a wireless command signal. The electronic command signal and the wireless command signal may be transmitted in response to ambient conditions, aircraft flight conditions, and aircraft mission.

A driving cam located within the housing is associated with an upstream side of the braking system. The driving cam is configured to rotate when a torque is applied to the upstream side. The braking system has a wedging cam and a plurality of cylindrical rollers. The wedging cam located within the housing and is associated with a downstream side of the braking system. The wedging cam is configured to react and prevent back-drive motion when torque is applied to the downstream side. The plurality of cylindrical rollers is positioned between the wedging cam and the housing. The plurality of cylindrical rollers is configured to wedge between a surface of the wedging cam and the housing when the torque is applied to the downstream side.

Abstract: The present disclosure relates to a secondary airfoil apparatus, system and method for improving lift, takeoff, landing and aerodynamic performance of a floatplane. The secondary airfoil can be integrated into the floatplane during manufacture, or retrofitted to an existing floatplane after manufacture. The secondary airfoil is itself of sufficient structural rigidity to withstand any and all forces added by the airfoil during floatplane operation. The secondary airfoil is fixedly attached between the floats of the floatplane, and are purposefully not attached to spreader bars that can exist typically between the floats. The secondary airfoil can be arranged at an optimal angle of incidence and vertical lift position relative to the primary airfoil, or wing of the aircraft, and relative to the floats center of gravity and drag for optimal maneuverability of the floatplane.

Abstract: A static aircraft seat privacy panel may include a body. At least a portion of a surface of the body may be shaped to at least partially conform with at least a portion of an aircraft seat. A lower edge of the body may be configured to couple to a floor via a set of floor-mounted components. The set of floor-mounted components may be within the floor separate from a set of seat tracks of an aircraft seat compliant with 16G force requirements for aviation transport. An upper edge of the body may be configured to be offset a selected distance from a surface of one or more overhead structures of the aircraft cabin when the body is coupled to one or more structures positioned proximate to a ceiling of the aircraft cabin. The static aircraft seat privacy panel may be compliant with 9G force requirements for aviation transport.
