Abstract: A rear wing for a motor vehicle includes a first end, a second end, and an aerodynamic surface including a pressure side extending between the first end and the second end, a first end plate is arranged at the first end, and a second end plate is arranged at the second end. At least one of the first end plate and the second end plate includes a selectively deployable aerodynamic surface.

Abstract: A method of forming an additive manufactured component comprises depositing a first layer of build material on a build platform within an additive manufacturing machine, depositing reinforcement fibers into the first layer of build material, orienting the reinforcement fibers within the first layer of build material, lowering the build platform, depositing a second layer of build material on top of the first layer of build material, depositing reinforcement fibers into the second layer of build material, and orienting the reinforcement fibers within the second layer of build material.

Abstract: A flow conditioning device includes a body portion having first and second ends and an interior surface defining a channel extending from the first end to the second end, and one or more flow conditioning elements disposed within the channel. Each of the one or more flow conditioning elements is integrally formed with the interior surface of the body portion, and may be a respective flow straightening tube, a flow straightening vane, a hole array plate, a turning vane, a swirling vane, a helical ridge formed along a respective longitudinal segment of the interior surface, or another configuration. The body portion and the one or more flow conditioning elements may be formed by an additive manufacturing process, and may optionally be made of the same material.
