The invention discloses a high-altitude long-endurance unmanned aerial vehicle layout with an ultrahigh lift-drag ratio, and belongs to the technical field of aircraft design. The invention provides an unmanned aerial vehicle layout which has ultra-long hang time and relatively high flight speed and is used for reducing the number of equipment in a flight formation under the condition of meeting global coverage. A fuselage is in lap joint with wings through a laminar flow hanging frame, a laminar flow nacelle is arranged at the tail of the fuselage, a power system is arranged in the laminar flow nacelle, a fuselage undercarriage is arranged at the bottom of the fuselage, and wing tip undercarriages are arranged at wing tips of the wings to complete take-off and landing work in a matched mode; empennages are arranged on the two sides of the laminar flow nacelle; the fuselage undercarriage adopts a bicycle type undercarriage, the empennage is a retractable empennage, the power system adopts an ultra-large bypass ratio power system, and the wings are variable oblique swept wings. According to the unmanned aerial vehicle layout, cross-generation improvement of the comprehensive performance of the high-altitude long-endurance unmanned aerial vehicle is achieved.

    一种超高升阻比的高空长航时无人机布局,属于飞行器设计技术领域。本发明提出一种既具有超长的滞空时间,可具有较高的飞行速度的无人机布局用以满足全域覆盖的条件下缩减飞行编队内的装备数量。本发明的机身通过层流挂架与机翼搭接,机身尾部布置层流短舱,层流短舱内设置有动力系统,机身底部布置机身起落架,机翼翼尖布置有翼尖起落架配合完成起降工作,层流短舱两侧布置有尾翼,机身采用吊舱式层流隐身化机身,机身起落架采用自行车式起落架,尾翼为可收放尾翼,动力系统采用超大涵道比动力系统,机翼为可变斜掠翼。本发明的无人机布局实现高空长航时无人机综合性能的跨代提升。
