Abstract:
PROBLEM TO BE SOLVED: To provide a pod for an unmanned aircraft capable of being removed and re-mounted. SOLUTION: The pod includes an outer shell, and various payloads are retained in an inner side. A first surface of a frame of the aircraft is provided with a plurality of connection parts or electric connection parts. A plurality of mounting parts are used for removably mounting the pod to the first surface. Accordingly, using the same unmanned aircraft, a wide range of payload can be transported by merely removing the pod and mounting it to an aircraft core fixed with the different pod. These pods are shaped so as to form a part of an outer part of the aircraft, and when the pods are mounted to the frame, they enhance air dynamic characteristic of the aircraft.

Abstract:
PURPOSE: A rotational bottom-blade vehicle is provided to implement scouting and observation in an indoor place as well as in a small space. CONSTITUTION: A fixed-pitch propeller(2) is horizontally installed around a central shaft(1). A power unit(3) is installed on the top of the central shaft of the propeller. A control unit(4) is installed on the bottom of the central shaft of the propeller, and includes a controller and a rudder(30). One end of each of first to forth attachment plates(11~14) is attached to the control unit in the form of cross. Legs(40) are vertically attached beneath the other end of each attachment plate. The rudder is attached to the bottom of the first and second attachment plates by hinges(32).
Abstract:
PROBLEM TO BE SOLVED: To provide a mode of controlling a drone that enables it to fly over typical turning paths.SOLUTION: Respective motors of a drone (10) can be controlled to rotate at different speeds in order to pilot the drone both in attitude and speed. A remote control appliance (16) produces a command to turn along a curvilinear path, and the command comprises a left or right turning direction parameter and a parameter that defines the radius of curvature of the turn. The drone receives the command and acquires instantaneous measurements of linear velocity components, of angles of inclination, and of angular speeds of the drone. On the basis of the received command and the acquired measurements, set-point values are generated for a control loop for controlling motors of the drone, and the set-point values control horizontal linear speed and inclination of the drone relative to a frame of reference associated with the ground so as to cause the drone to follow the curvilinear path at a predetermined tangential speed (u).
