The invention discloses a fixed-wing unmanned aerial vehicle for surveying and mapping, which comprises a front vehicle body, a shape-preserving surveying and mapping pod, a vehicle body deformation device, a rear vehicle body, a connection rotating device, a rear wing, a semi-rigid transition wing section and a bendable dish-shaped polyhedral frame, the shape-preserving surveying and mapping pod is arranged at the bottom of the front vehicle body, and the vehicle body deformation device is arranged at the rear part of the front vehicle body; the invention relates to the technical field of engineering surveying and mapping. According to the fixed-wing unmanned aerial vehicle for surveying and mapping, a variable connecting wing pneumatic layout and a rear power and front three-point type shape correction undercarriage layout are adopted, and the problems that an unmanned aerial vehicle with a high aspect ratio is difficult to execute aerial survey tasks in weather with large wind power and an unmanned aerial vehicle with a small aspect ratio is difficult to economically execute aerial survey tasks at a low flight speed can be solved; the unmanned aerial vehicle executes an aerial survey task in the mode of the minimum sweepforward angle and the maximum aspect ratio so as to prolong the space time and improve the use economy, and when the low-altitude wind power is increased, the unmanned aerial vehicle continues to work in the mode of the small aspect ratio.

    本发明公开了一种测绘用固定翼无人机,包括前机体、保形测绘吊舱、机身变形装置、后机体、连接转动装置、后翼、半刚性过渡翼段和可变弯碟形多面体架,保形测绘吊舱设置在前机体的底部,机身变形装置设置在前机体的后部,本发明涉及工程测量测绘技术领域。该测绘用固定翼无人机使用可变联接翼气动布局、后置动力和前三点式修形起落架布局,可解决大展弦比无人机难以在风力较大的天气执行航测任务,小展弦比无人机难以在较低的飞行速度下经济地执行航测任务的问题,当天气良好时,该无人机以最小前掠角和最大展弦比模式执行航测任务,以延长留空时间,提高使用经济性,当低空风力增大时,该无人机以小展弦比模式继续工作。
