Abstract: Air-ground vehicle fuel tank configurations and associated features are described that can be incorporated in the structural design of a vehicle in ways that improve both the ground mobility and flight capability of the vehicle. A vehicle frame may include a fuel tank with a main tank and two or more auxiliary tanks. The main tank may be disposed along the centerline of the vehicle, and the auxiliary tanks may extend upward and outward from the main tank, for example forming a “V” shape when viewed from the front. The auxiliary tanks may be substantially arc-shaped, when viewed from the side of the vehicle, and may be attached to the main tank at each end of the arc-shape. Each of the auxiliary tanks may include an attachment mechanism configured to attach to an airfoil suspension at or near an apex of the auxiliary tanks.

Abstract: Ground vehicles that may include flight capability are described. In some examples, a vehicle frame may include a fuel tank with a main tank and at least two auxiliary tanks, with the main tank disposed substantially along the centerline of the vehicle, and the at least two auxiliary tanks extending upward and outward from the main tank. In some examples, vehicles may include a chassis, a cage attached to the chassis, a front wheelbase attached to the chassis and/or cage, a rear wheelbase attached to the chassis and/or cage, a ground steering mechanism connected to the front wheelbase and/or the rear wheelbase, a motor connected to a propeller, and a propeller shroud at least partially encircling the propeller.
