Abstract: An aerial system includes a body, a propeller coupled to the body, and a motor coupled to the propeller. The motor is configured to rotate the propeller in a first direction, wherein an other portion of the aerial system rotates in an opposing second direction. The other portion of the aerial system that rotation in the opposing second direction may be the body or a second propeller. The aerial system also includes a processing system configured to control the motor to cause the aerial system to hover in a substantially fixed pose, and a camera configured to obtain images of an environment proximate the aerial system while the aerial system is hovering.

Abstract: An aerial vehicle, preferably including: a rotary wing and a protection housing enclosing the rotary wing. An aerial vehicle, preferably including: a first rotary wing module including a first rotary wing and a second rotary wing module including a second rotary wing, wherein the first rotary wing module and the second rotary wing module are preferably operable between a folded configuration and an unfolded configuration. A method of aerial vehicle operation.

Abstract: A foldable drone is provided to improve the portability of the drone, which includes a drone body and a rotary wing part connected to the drone body. The rotary wing part includes a first rotary wing module and a second rotary wing module with each having at least one rotary wing, and the first rotary wing module and the second rotary wing module are respectively articulated to two sides of the drone body, to allow the first rotary wing module and the second rotary wing module to rotate about their respective articulating shafts, so as to be folded or unfolded.

Abstract: An aerial system, preferably including one or more housings. A housing for an aerial system, preferably including: a first and second piece that cooperatively surround one or more propellers of the aerial system; and a retention mechanism that removably couples the first piece to the second piece. A method for aerial system operation, preferably including attaching and/or detaching housing pieces of the aerial system.

Abstract: An aerial vehicle including a housing, an outrunner motor including a stator mechanically coupled to the housing and a rotor rotationally coupled to the stator, and a propeller removably coupled to the rotor, the propeller including a hub and a plurality of propeller blades. A rotor, a propeller including a hub and a propeller blade, a radial alignment mechanism, a rotational retention mechanism, and an axial retention mechanism.

Abstract: A fully protected drone includes a drone body and a rotary wing connected to the drone body, and further includes a protection housing connected to the drone body. The protection housing is a meshed closed housing and has a hollow cavity. The rotary wing is mounted in the hollow cavity. According to the present application, the rotary wing is mounted in the hollow cavity of the protection housing, the rotary wing will not contact the human body, thus an operator can fly or retrieve the drone by hand, which improves the operation convenience of the rotary wing, and improves the operation security to a large extent. The protection housing is configured as a meshed closed housing. The rotary wing is mounted in the protection housing connected to the drone body, thereby reducing the overall height of the drone and improving the portability of the drone.
