Patent number: 11932427Abstract: Provided is an unmanned aircraft which is capable of stably taking off. In one example, the unmanned aircraft has an aircraft body which includes an information acquisition device, a plurality of rotary wings, and a protective member disposed around the rotary wings. Each of the rotary wings has a rotation axis which is tilted with respect to a vertical direction by a given angle, such that the rotary wings generate a forward thrust force. The aircraft body has a lower edge which includes a middle lower edge and a forward lower edge, wherein the protective member has a lower edge including the forward lower edge. The forward lower edge is located above the middle lower edge, and the forward lower edge has a rear end located backward of a rear end of the rotary wing.Type: GrantFiled: August 16, 2021Date of Patent: March 19, 2024Assignees: ACSL Ltd., NIS Co., Ltd.Inventors: Soki Kuga, Yusuke Inagaki, Patrik Ken Takeuchi
