One of the perspective trends of improving aerial vehicle design, including small-size unmanned aircrafts is the morphing wing technology that is based on principles of adapting the wing configuration to aircraft flight conditions. For small-size aircrafts, this problem is still open because airflow over the wing corresponds to low Reynolds numbers Re ≤ 300 000 due to the main factors: small shape and low speed. As a result, the boundary level is separated at the upper surface of the aerofoil and transitions to turbulent flow and then reattaches to the surface forming a laminar separation bubble. A small-size aircraft shows a worse lift force and the aircraft performance. This article analyzes a possibility for increasing the lift force of a small-size unmanned aircraft by morphing the aerofoil configuration: in the wing plane, outside the wing plane and in the transverse plane of the wing. This required an analysis of acceptable morphing wing concepts of morphing by changing the wing area, sweep and changing the area together with sweep.
