Low-power-consumption unmanned aerial vehicle based on dynamic gliding

The invention discloses a low-power-consumption unmanned aerial vehicle based on dynamic gliding. The unmanned aerial vehicle comprises a shaped air bag, deformation air bags, and wings, wherein an inner portion of the shaped air bag is supported by a high-strength framework, and the shape of the air bag can be kept unchanged in a deflating process; the deformation air bags are connected with theshaped air bag through a three-way pipe, three connectors of the three-way pipe are connected with the shaped air bag and the two deformation air bags respectively, the total volume of each deformation air bag is half of the volume of the shaped air bag, and density of air filled in the shaped air bag and the deformation air bags is lower than the density of air; and a pitch axis of each wing is connected with a bearing seat arranged at the bottom of the three-way pipe through a bearing. According to the unmanned aerial vehicle, gliding advancing is utilized, an effective attack angle is smallin a gliding process, a r
