A fluid machine includes: a shaft portion extending in an axis direction; a shroud provided to surround the shaft portion and having a diameter decreasing from an upstream side on one side in the axis direction toward a downstream side on another side in the axis direction, a flow path being formed between the shroud and the shaft portion and having a flow path cross-sectional area decreasing toward the downstream side; a propeller rotatably provided about an axis between the shaft portion and the shroud and configured to pump a fluid from the upstream side toward the downstream side; and a motor provided to correspond to the propeller, the motor including a rotor having a ring-like shape and being fixed to an outer circumference portion of the propeller and accommodated in the shroud and a stator having a ring-like shape surrounding the rotor and being fixed in the shroud, in which the motor is a conical motor in which diameters of the rotor and the stator decrease from the upstream side toward the downstream side.

Fluid machine and underwater vehicle

A fluid machine includes: a shaft portion; a shroud having an inside surface with a diameter decreasing from an upstream side toward a downstream side, a flow path being formed between the shroud and the shaft portion and having a flow path cross-sectional area decreasing toward the downstream side; a propeller rotatably provided about an axis between the shaft portion and the shroud and configured to pump a fluid from the upstream side toward the downstream side; and a motor provided to correspond to the propeller and including a rotor having a ring-like shape fixed to an outer circumference portion of the propeller and accommodated in the shroud and a stator having a ring-like shape surrounding the rotor and fixed in the shroud, in which a plurality of the propellers are provided to be spaced apart in the axis direction, the motors are provided in an identical number to the propellers to correspond to each of the propellers, and of a plurality of motors, the rotor of the motor positioned more on the downstream side has a smaller average outside diameter.

Fluid machine for underwater vehicle and underwater vehicle

A fluid machine includes: a shaft portion extending in an axis direction; a shroud provided to surround the shaft portion, and forming a flow path between the shroud and the shaft portion, the flow path having one side in the axis direction serving as an upstream side and another side in the axis direction serving as a downstream side; a first propeller provided rotatably around the axis between the shaft portion and the shroud; a second propeller provided rotatably around the axis between the shaft portion and the shroud on the downstream side of the first propeller; an outer periphery driving motor provided in the shroud and configured to rotationally drive the first propeller; and an inner periphery driving motor provided in the shaft portion and configured to rotationally drive the second propeller in a direction opposite to the rotational direction of the first propeller.

A fluid machine includes: a shaft portion extending in an axis direction; a shroud provided to surround the shaft portion, and forming a flow path between the shroud and the shaft portion, the flow path having one side in the axis direction serving as an upstream side and another side in the axis direction serving as a downstream side; a propeller provided rotatably around the axis between the shaft portion and the shroud; a motor provided in the shroud and configured to rotationally drive the propeller; and a bearing apparatus provided only to the shaft portion, out of the shroud and the shaft portion, and rotationally supporting the propeller.

A positioning member is a carrier positioning member that is fixed to a base and that positions, on the base, a carrier storing a plurality of plate-shaped loads such that front faces or rear faces thereof face the base. The positioning member comprises two front-side stoppers that come into contact with two opening edge parts being end parts of an opening in the carrier, and restrict movement of the carrier to a front side, and two rear-side stoppers that come into contact with two plate-shaped end parts formed on a rear side in the carrier, and restrict movement of the carrier to the rear side and movement in a direction vertical to the base.

Carrier positioning member and carrier placement platform

Provided is an aerial vehicle having a structure in which a rotating body has been excluded from a portion that can be touched by a user during flight. An aerial vehicle includes: a balloon unit; a control unit provided at the bottom of the balloon unit; and a plurality of micro-mechanisms (micro blowers), each of which blows out air. The micro blowers have a structure in which a vibrating member is vibrated in a space in communication with a plurality of openings, thereby blowing out, through a second opening, the air that has flowed into the space through a first opening. The control unit controls the micro blowers to change the position or the attitude of the aerial vehicle.

Aerial vehicle

A fluid machine includes: a shaft portion; a shroud surrounding the shaft portion and including an inside surface that forms a flow path-forming surface defining a flow path with the shaft portion; a first propeller rotatably provided in the flow path; a second propeller rotatably provided on a downstream side of the first propeller in the flow path; and a motor including a rotor that is fixed to an outer circumferential portion of the second propeller and that is accommodated in the shroud, and a stator that surrounds the rotor via a clearance and that is fixed in the shroud. A portion of the flow path-forming surface on a downstream side of the second propeller decreases in diameter toward the downstream side, and the shroud includes an inlet flow path that is open at a portion between the first propeller and the second propeller of the flow path-forming surface.
