UNMANNED STEALTH AIRCRAFT Russian patent published in 2009 - IPC B64C39/02 B64C39/10 

FIELD: aircraft industry.

SUBSTANCE: invention refers to aircraft industry, and namely to unmanned stealth aircrafts. Unmanned stealth aircraft is made according to "flying wing" aerodynamic design in horizontal plane in the form of a rhomb all the four wing edges of which are equal to each other lengthwise, and front wing edges are parallel to rear wing edges which are located opposite. Front wing edges make 40 deg angles with a straight line perpendicular to longitudinal axis. Each elevon on the rear wing edges is three-section, and has individual and independent control of each section. Inlet holes of air intakes are made so that they do not project beyond the clean line of aircraft upper surface; they are made in the form of triangles if to look from above. Flat outlet nozzle is made so that it does not project beyond the lines of wing center section, and its lower edge coincides with rear edge of wing center section.

EFFECT: improving unmanned aircraft stealthiness, and improving in-flight stability and controllability.
