Provided is a gas turbine system in which electricity consumption of a battery when starting or stopping a gas turbine engine is reduced and sufficient battery power during flight can be secured. The present invention includes a plurality of gas turbine engines 21, 22, and 23, generators 41, 42, and 43, a battery 5, and a controller 7. The controller 7 decides at least one main starting gas turbine engine 21 from the plurality of gas turbine engines before the plurality of gas turbine engines are started, starts the main starting gas turbine engine 21 using electricity from the battery 5, and starts the secondary starting gas turbine engines 22 and 23 of the plurality of gas turbine engines other than the main starting gas turbine engine 21 using electricity from the generator 41 connected to the main starting gas turbine engine 21 after the main starting gas turbine engine 21 reaches a steady state.

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.

Provided is a method for an unmanned aerial vehicle to handle goods in cooperation with an autonomous vehicle. The method comprises capturing, by the unmanned aerial vehicle, an image of the autonomous vehicle having a goods storage box, recognizing, by the unmanned aerial vehicle, a marker displayed in the goods storage box by analyzing the captured image, identifying, by the unmanned aerial vehicle, a region occupied by the marker on the captured image, adjusting a relative position of the unmanned aerial vehicle and the autonomous vehicle, wherein the marker displayed in the goods storage box is covered by a lid of the goods storage box and placed in a state that cannot be captured by the unmanned aerial vehicle, and the marker is exposed in a state that can be captured by the unmanned aerial vehicle only when the lid of the storage box is opened by communication between the unmanned aerial vehicle and the autonomous vehicle.

In one embodiment there is provided a flying toy that can be manually pumped with air. The pressurized air is kept in a canister and use to drive a propeller to propeller the toy for flight.

An unmanned aerial vehicle (UAV) comprises a flight control system and an electromechanical system directed by the flight control system. The flight control system is configured to track a position of a beacon that is in motion and monitor a difference between an actual position of the unmanned aerial vehicle and a desired position of the unmanned aerial vehicle relative to the position of the beacon. The flight control system configures one or more flight objectives based on one or more factors comprising whether the difference between the actual position and the desired position exceeds a threshold, wherein the flight objectives comprise a velocity objective and a position objective. The flight control system also commands the electromechanical system based at least on the one or more flight objectives.

Stereo ranging systems having pairs of imaging devices may be calibrated by projecting beams of light into the fields of view of the imaging devices and comparing the appearances of reflections of the beams depicted within images captured thereby. Where the reflections appear consistently within the images, the stereo ranging systems may be determined to be calibrated and operating properly. Where the reflections do not appear consistently within the images, the stereo ranging systems may be determined to be not calibrated or not operating properly. The light sources may be light-emitting structures such as diodes or reflective objects. A vector generated based on inconsistencies in appearances of reflections within images may be used to adjust the images. Images adjusted based on such vectors may be used to determine ranges to objects depicted therein or for any other purpose.

A movable device includes: at least one lift generating unit for generating a pressure difference between opposite sides thereof to generate a lift force; a movable device body connected to the lift generating unit to be movable by means of the lift force generated by the lift generating unit; and at least one supply duct, the number of which corresponds to the number of the lift generating unit, wherein on end of the supply duct is disposed on one side of the lift generating unit and, when the lift generating unit operates, fluid is suctioned through the other end of the supply duct to be supplied into the lift generating unit.

Shape memory actuators may be used in unmanned aerial vehicles to control various components. For example, shape memory actuators may adjust cant angles of motors, propellers, and other propulsion mechanisms. In addition, shape memory actuators may adjust positions or orientations of various other components of unmanned aerial vehicles, including wings, control surfaces, motor arms, frame sections, payload doors, and landing gears. The shape memory actuators may be formed of various shape memory materials, may be one-way or two-way shape memory actuators, and may change their configurations responsive to heat and/or magnetic fields.
