Abstract: A rail extension, comprising: a base extending from an end of the rail extension, wherein the base includes vehicle rail attachments configured to attach to a vehicle rail; a front member configured for attachment to a bumper beam; a body extending from the base to the front member; wherein the body comprises reinforcing members; wherein the body comprises a first polymeric material; wherein the reinforcing members comprise a second polymeric material.

Abstract: A beam configured to couple to a vehicle includes end areas comprising end midpoints that are equidistant from a top face and a bottom face on a vertical axis when the beam is positioned on a vehicle, and a central area positioned between the end areas, the central area having a central area midpoint that is equidistant from the top face and the bottom face on the vertical axis when the beam is positioned on a vehicle and that is positioned in the center of the beam along the longitudinal axis. The longitudinal axis of the beam passes through the end area, wherein the central area is capable of rotating about the longitudinal axis when the beam is impacted by an applied force.

Abstract: A cooling arrangement for a gas turbine engine includes a discharge channel for airflow from a compressor, a first cooling channel, and at least one aperture providing communication between the flow of air through the discharge channel and the first cooling channel. A restrictor device in the aperture regulates the flow of air between the discharge channel and the first cooling channel. The restrictor device deforms to vary air flowing through the aperture in response to a physical condition of the engine. This physical condition of the engine may be that of the temperature of air flowing through the discharge channel or the power output of the gas turbine engine. The restrictor device may be a boreplug, which may be a two-way shape memory alloy.
