  • Patent number: 11433954
    Abstract: A vehicle includes a first trailer having a rear end, and a second trailer having a front. The second trailer is coupled to the first trailer. The vehicle also includes at least one flexible membrane that includes a perimeter coupled to the rear end. A seal is formed between the perimeter and the rear end. The vehicle further includes a pressurization source coupled to the vehicle, and at least one port defined in and extending through the rear end. The at least one port is enclosed by the perimeter and in fluidic communication with the pressurization source. In a deployed profile, the at least one flexible membrane extends between the rear end of the first trailer and the front of the second trailer.

  • Patent number: 11325662
    Abstract: A system for reducing drag on a trailer includes a flexible membrane including a perimeter coupled to a rear end of the trailer. A variable-volume cavity is defined between the flexible membrane and the rear end. The system also includes a source of pressurized gas coupled to the trailer and in fluidic communication with the variable-volume cavity, and a controller operable to control a flow of the pressurized gas from the source to the variable-volume cavity such that the flexible membrane is moved from a stowed profile, wherein the flexible membrane is collapsed against the rear end of the trailer, to a first deployed profile, wherein the flexible membrane is maintained in a first pre-selected tapered aerodynamic shape projecting rearward from the rear end.
