Abstract: The landing gear actuation system includes an attachment point integral to a movable member, a flexible pull member having a first end coupled to the attachment point, and a motor configured to move the flexible pull member, wherein the movement of the flexible pull member moves the attachment point and the movable member.

Abstract: A shock strut assembly is disclosed herein. The shock strut assembly includes a shock strut cylinder defining a mixed fluid chamber, a shock strut piston defining a liquid chamber, the shock strut piston operatively coupled to slide within the shock strut cylinder, an orifice support tube coupled to the shock strut cylinder and defining an orifice between the liquid chamber and the mixed fluid chamber, a retainer housing coupled to the orifice support tube and configured to restrict a flow of liquid from the liquid chamber to the mixed fluid chamber, a spring retainer coupled to the orifice support tube and disposed over the retainer housing, and a spring disposed between the retainer housing and the spring retainer.

Abstract: A helically shaped dynamic seal ring is provided. The helically shaped dynamic seal ring includes a spirally wound body and a snubbing orifice area formed in the spirally wound body. The spirally wound body is configured to expand in response to contacting a snubbed stroke range of an actuator piston. The spirally wound body is configured to contract in response to distancing from the snubbed stroke range of the actuator piston.

Abstract: A metering unit is provided. The metering unit includes a metering pin analog and a translation shaft. The metering pin analog is configured to translate about the translation shaft in a first direction in response to a load pressure acting on an annular region of a bottom portion of the metering pin analog. The metering pin analog is configured to translate about the translation shaft in a second direction opposite the first direction in response to the load pressure ceasing.

Abstract: A metering pin for use in a multi-actor damping system is disclosed herein. The multi-actor damping system may be used in a shock strut assembly to alter a damping curve of the shuck strut assembly. The metering pin may be configured to transition the multi-actor damping system from a first damping actor configuration to a second damping actor configuration. The first damping actor configuration may correspond to a first damping curve. The second damping actor configuration may correspond to a second damping curve. The first damping curve being different than the second damping curve.

Abstract: A landing gear actuation system is disclosed herein. The landing gear actuation system includes a trunnion sprocket coupled to a movable member, a drive motor, and a flexible drive member extending between and to the motor and the trunnion sprocket. The motor is configured to move the flexible drive member, wherein the movement of the flexible drive member moves the trunnion sprocket and the movable member. The flexible drive member may be a belt or a chain.
