Vehicle configuration with aerodynamic shaping to reduce drag, and vehicle and method for the same

A vehicle comprising:

• a vehicle configuration to reduce drag in an air stream, the vehicle configuration comprising:
• a vehicle body;
• at least one auxiliary body coupled to, and positioned a distance from the vehicle body, to form a channel between the at least one auxiliary body and the vehicle body, wherein an air flow from the air stream comprises a compressible air flow moving at one of, transonic speed, subsonic speed, or supersonic speed, through the channel;
• and
• one or more exterior profiles of one or more of, the vehicle body, and the at least one auxiliary body, the one or more exterior profiles positioned in proximity to the channel, and shaped with an aerodynamic shaping, so that the one or more exterior profiles each comprises one or more concave shape portions,
• wherein when the air flow from the air stream flows through the channel, the drag resulting from air flow interactions between the vehicle body and the at least one auxiliary body is reduced.

A method to reduce drag of a vehicle in a fluid stream, the method comprising:

• providing a vehicle configuration for the vehicle, the vehicle configuration comprising:
• a vehicle body;
• at least one auxiliary body coupled to, and positioned a distance from, the vehicle body, to form a channel between the at least one auxiliary body and the vehicle body;
• and
• one or more exterior profiles of one or more of, the vehicle body, and the at least one auxiliary body, the one or more exterior profiles positioned in proximity to the channel;
• shaping the one or more exterior profiles with an aerodynamic shaping, so that the one or more exterior profiles each comprises one or more concave shape portions, and the one or more exterior profiles comprise one or more of, a longitudinal contour with a longitudinal concavity, and a lateral contour with a lateral concavity;
• and
• reducing, with the vehicle configuration having the one or more exterior profiles shaped with the aerodynamic shaping, the drag resulting from fluid flow interactions between the vehicle body and the at least one auxiliary body, when a fluid flow from the fluid stream flows through the channel.
