A first embodiment includes a circuit based aerial vehicle including an enclosed air duct circuit with a plurality of fans within respective fan tunnels and a plurality of rotating archway assemblies. The rotating archway assemblies may include respective cylinder casings with medial archways, actuating collars at opposing ends of the cylinder casing, and a rotational cylinder rotatable along its longitudinal axis. The actuating collars may be structured to spin their respective cylinder casings along the cylinder casing longitudinal axes thereby orienting the rotational cylinders in different positions along their medial axes.

A second embodiment includes rounded cylinder assemblies with respective bulbous cylinder casings including medial actuating collars that rotate rather than the entire cylinder casing. The actuating collars themselves are structured to spin their respective rotational cylinders along the rotational cylinder longitudinal axes to orient the rotational cylinders in different positions along their medial axes.

A motor-integrated fluid machine includes a rotating part that rotates around a rotation axis; an outer peripheral part provided at an outer periphery of the rotating part; and an outer peripheral drive motor that provides power from the outer peripheral part to rotate the rotating part. The rotating part includes a rotating support ring around the rotation axis, and blades provided on a center side of the ring and provided side by side in a circumferential direction of the rotation axis. The motor includes a rotor side magnet provided on an outer peripheral side of the ring in a radial direction, and a stator side magnet provided on an inner peripheral side of the outer peripheral part to face the magnet. The motor-integrated fluid machine includes a restraining part which covers and restrains the ring and the magnet from an outside to integrate the ring and the magnet
