摘要：【中文】本发明提供一种可长航时宽速域高机动巡飞的无人飞行器。该巡飞无人飞行器主要包括：机身、设置在所述机身两侧的一对可折叠的机翼内翼段、沿展向可伸缩的机翼外翼段，设置在所述机身尾部的一对可折叠上V型尾翼、一对可折叠腹鳍以及机身尾部的动力。所述机身两侧的两个可变体折叠机翼根据使用需求，可在机翼自身所在平面内转动，实现折叠与变后掠翼功能；所述沿展向可伸缩的外翼段，以辅助增大机翼展弦比；所述机身尾部的一对可折叠上V型尾翼和一对可折叠腹鳍，以增强机动性，相对常规尾翼具有低的阻力特性；所述动力安装于机身后段，可选安装涡喷动力、活塞动力、涡喷/活塞双动力，使巡飞无人飞行器高效稳定飞行。折叠机翼在不同速度下位置的变换，以及沿展向可伸缩的外翼段，可折叠的上V型尾翼、可折叠腹鳍、机身尾部动力，共同提高了巡飞无人飞行器在不同速度环境下的适应能力。 【EN】The invention provides an unmanned aerial vehicle capable of long-endurance, wide-speed-range and high-maneuvering cruising. This patrol and fly unmanned vehicles mainly includes: the aircraft comprises an aircraft body, a pair of foldable wing inner wing sections arranged on two sides of the aircraft body, a wing outer wing section capable of stretching along the unfolding direction, a pair of foldable upper V-shaped empennages arranged on the tail part of the aircraft body, a pair of foldable ventral fins and power of the tail part of the aircraft body. The two variable folding wings on the two sides of the machine body can rotate in the plane where the wings are located according to use requirements, so that the functions of folding and variable sweepback wings are realized; the outer wing section is telescopic along the spanwise direction so as to assist in increasing the aspect ratio of the wing; a pair of foldable upper V-shaped empennages and a pair of foldable ventral fins at the tail part of the fuselage to enhance maneuverability, and the tail wing has low resistance characteristic compared with the conventional empennages; the power is installed in the rear section of the aircraft body, and the turbojet power, the piston power and the turbojet/piston dual power can be selectively installed, so that the cruise unmanned aircraft can fly efficiently and stably. The positions of the folding wings are changed at different speeds, the outer wing sections which can stretch along the unfolding direction, the folding upper V-shaped empennage, the folding ventral fins and the power of the tail of the unmanned aerial vehicle body jointly improve the adaptability of the cruise unmanned aerial vehicle under different speed environments.
