FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering. Drone aircraft comprises power plant consisting of piston engine and extra motors coupled with their relevant propellers, fuselage, wings, fin and stabilising plates. Wings are secured to fuselage sequentially, one higher the other by 5% to 10% of wing chord. Distance between previous wing rear edge and next wing front edge makes 5% to 15% of wing chord. Wings represent sweep forward and sweep back, sweep making up to 20°. Power plant comprises main engine provided with one or two screws and secured to fuselage to turn vertically through ±15°, and extra motors secured on first wing.
