Abstract
In aviation the aircraft aerodynamic scheme "tandem" with comparable areas of front and rear wings is known. The aerodynamic "tandem" scheme benefits by lift and cargo capacity with limited wing widths. Due to this it has found a new application in modern unmanned aerial vehicles (UAVs). However, an increase in the number of bearing surfaces also leads to an increase in the aircraft frontal resistance due to their negative interference. To reduce the reciprocation of the wings, i.e. to increase the aerodynamic quality and the transverse and track resistance of aircraft, the V- shaped wings are used. Theoretically, if you give the wing-high-plane a positive V-shaped and wing-low-plane-negative, this will reduce the impact of the front wing to the rear. The experiment really proved the ability to significantly increase the aerodynamic quality in this way (ΔKmax = 1.0 or about 10%). But the possibility of calculating the effect of numerical methods remains questionable.
