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.
