  • Publication number: 20170183081
    Abstract: A multi-rotor passenger-carrying aircraft with foldable aircraft arm is disclosed, including an aircraft body, a fixing mechanism, a connector and an aircraft arm. The fixing mechanism is fastened on the aircraft body, an end of the aircraft arm is articulated to the fixing mechanism, the fixing mechanism is provided with at least one first mounting hole, and the aircraft arm is provided with at least one second mounting hole. When the aircraft arm is in a folded state, one end of the connector is removably attached to the fixing mechanism through a first fastener, and the other end of the connector is removably attached to the aircraft arm through a second fastener, so that the fixing mechanism is kept to be at a first angle with the aircraft arm. When the aircraft arm is in a working state, a third fastener is adapted to pass through both the first and second mounting holes to cause the fixing mechanism to be fixedly connected to the aircraft arm and kept at a second angle with the aircraft arm.

  • Publication number: 20170183088
    Abstract: A multi-rotor passenger-carrying aircraft is disclosed, including an aircraft body with a passenger-carrying cabin and at least three aircraft arms arranged on the aircraft body. Each of the at least three aircraft arms is provided with a first propeller arranged above the aircraft arm and driven to rotate by a first driving device, and a second propeller arranged below the aircraft arm and driven to rotate by a second driving device. The aircraft can effectively reduce the area it occupies and meet the requirement of carrying capacity by arranging propellers of smaller size both above and below each aircraft arm instead of separately arranging a propeller of larger size on each aircraft arm in traditional means. Meanwhile, the multi-rotor passenger-carrying aircraft can implement various flight actions during flight by adjusting the rotate speed of the different driving devices respectively, which is convenient to control, with good maneuverability and controllability.
