A completely transparent spherical body is surrounded externally by a plurality of leaf plates arranged in equal spacing along a main outer ring rack of the spherical body. Two rubber tires are included to wrap the spherical body. A rider inside the spherical body pedals to rotate the spherical body forward. A vehicle having the spherical body can be autonomously operated to move on land or water, and in the air. In addition, to operate this vehicle, no specific road or environmental requirement is needed, and no other obstacle, even a traffic accident can stop its movement.

An aircraft is provided. The aircraft includes a ducted wing portion and a fan chamber. The fan chamber is attached to a bottom of the ducted wing portion. A fan assembly is provided in the fan chamber and is operative to blow air through the ducted wing portion. The ducted wing portion is configured to direct air blown by the fan assembly down to provide lift for the aircraft.

A wing for an aircraft is disclosed having a main wing, a high lift body, and a connection assembly movably connecting the high lift body to the main wing, such that the high lift body can be moved between a retracted position and at least one extended position. The connection assembly includes a drive system having a first drive unit and a second drive unit, wherein the first drive unit has a first input section coupled to a drive shaft, a first gear unit and a first output section drivingly coupled to a first connection element. The second drive unit has a second input section coupled to the drive shaft, a second gear unit, and a second output section drivingly coupled to a second connection element. The first output section includes a first output wheel and the second output section includes a second output wheel.

A slat track roller assembly is provided so as to mount a slat track operatively associated with a wing leading edge slat for movements between retracted and deployed conditions relative to a leading edge of an aircraft wing. The slat track roller assembly may include at least forward and aft pairs of roller mechanisms connected to a respective one of opposed wing ribs of the wing leading edge in operatively rolling contact with a respective opposed lateral edge of the slat track. At least one of the roller mechanisms is positionally adjustable relative to the respectively opposed lateral edge of the slat track so as to compensate for mechanical tolerances that may be present.

An unmanned vehicle including a vehicle body, propulsion system, maneuvering system, vehicle control system, rack, sensor, and a power supply. The vehicle control may be used to control the unmanned vehicle in combination with the propulsion and the maneuvering system. The rack may include a retractable mount that may move between a down position and an up position. The sensor system may include a plurality of transient object detection sensors. The plurality of transient object detection sensors may include a sensor adapted to detect an item of interest and may provide an item of interest signal to the vehicle control system. The vehicle control system may identify an item of interest classification and may provide a classification signal. The classification signal may be determined by the item of interest classification and may be utilized to avoid detection of the unmanned vehicle by the item of interest.

An aircraft convertible between fixed-wing and hovering orientations includes a fuselage. The aircraft includes a main wing pair comprising two opposing wings attached to the fuselage, where each wing of the two opposing wings includes a fixed wing section attached to the fuselage and a movable wing section rotatably mounted to the fixed wing section. The aircraft includes at least a first propulsor mounted to the movable wing section of each of the two opposing wings. The aircraft includes at least a first rotation mechanism attached to the fixed wing section and movable wing section of each of the two opposing wings, the at least a first rotation mechanism configured to rotate the movable wing section between a first movable wing section position parallel to the fixed wing section and a second movable wing section position perpendicular to the fixed wing section.
