    摘要: An illustrative example embodiment of a transport refrigeration system includes an evaporator air management system having an evaporator heat exchanger and an air passage downstream of the evaporator heat exchanger. A two-stage fan assembly within the air passage includes a first fan stage having a first fan rotor, a first motor associated with the first fan rotor for selectively causing the first fan rotor to rotate in a first direction about a fan axis, a second fan stage having a second fan rotor in series with the first fan rotor, and a second motor associated with the second fan rotor for selectively causing the second fan to rotate in a second, opposite direction about the fan axis. The first and second fan stages draw air across the evaporator heat exchanger and through the air passage.

    摘要: A method for estimating a trailer wheel position includes identifying a first set of wheel locations in a first image. Each of the wheel locations in the first set of wheel locations is associated with a corresponding trailer angle. The first set of wheel locations is clustered and a primary cluster in the first set of wheel locations is identified. A best fit curve is applied to the primary cluster. The best fit curve is a curve associating wheel position to trailer angle. An estimated wheel position is determined by applying a determined trailer angle to the best fit curve in response to the wheel being hidden in the first image. The estimated wheel position is output to at least one additional vehicle system.

    摘要: A gas turbine engine component includes a component wall that has an exterior core gaspath side and an opposed interior side. The component wall is formed of a ceramic matrix composite that includes a plurality of fiber plies disposed in a ceramic matrix. The component wall includes a corner that connects first and second wall sections. The fiber plies extend continuously through the first wall section, the corner, and the second wall section. The fiber plies are in a stacked contiguous arrangement in the first and second wall sections and at least some of the fiber plies separate from one another in the corner to define one or more void pockets there between.
