A system for rolling landing gear is illustrated. System includes a skid component attached to an aircraft and comprising at least a skid tube oriented laterally to a longitudinal axis of the aircraft. System also includes at least a wheel journaled on a rotational fulcrum and at least a biasing means attaching the rotational fulcrum to the skid tube, wherein the biasing means comprises at least a leaf spring and exerts a recoil force resisting upward displacement of the rotational fulcrum with respect to the skid tube.

Various implementations directed to composite skid member with varying cross-sections are provided. In one implementation, an aircraft landing gear assembly may include two composite skid members configured to contact the ground, where each composite skid member includes a first cross-section and a second cross-section, and where the first cross-section is different than the second cross-section. The aircraft landing gear assembly may also include two cross members configured to couple to a fuselage of an aircraft and configured to interconnect the two composite skid members.

This disclosure provides an unmanned aerial vehicle, including a central body; a plurality of arms, connected to the central body; a plurality of motor mounting bases, respectively disposed at ends of the plurality of arms away from the central body; a plurality of motors, respectively mounted on the plurality of motor mounting bases; a plurality of propellers, respectively connected to the plurality of motors, wherein the plurality of motors is configured to drive the propellers to rotate; and a plurality of antennas, respectively disposed on the plurality of motor mounting bases, wherein the plurality of propellers is located lower than the plurality of antennas. The unmanned aerial vehicle provided by this disclosure may ensure open space for mounting the antennas, featuring longer flight duration, fewer folding steps, and a higher storage speed.

Embodiments of the present invention relate to the field of aircraft technologies, and provide an unmanned aerial vehicle including an unmanned aerial vehicle body and a landing gear. The landing gear is entirely accommodated in the unmanned aerial vehicle body when being in a folded state. When being folded, the landing gear in the present invention is entirely accommodated in the unmanned aerial vehicle body, and therefore neither causes unnecessary resistance in air nor blocks an aerial photographing field of view in an aerial photographing process of the unmanned aerial vehicle. In addition, when the unmanned aerial vehicle is not in use, the landing gear is accommodated in the unmanned aerial vehicle body, so that the unmanned aerial vehicle is very compact in structure and easy to accommodate and carry.
