Stealth unmanned aerial vehicles

摘要

The invention relates to aviation engineering, in particular, to a class of unmanned aerial vehicles. Unmanned aircraft wing has diamond shape in plan with a sweep angle of the front and rear edges 35 ± ⁰ -45 ^0, a profile of relative thickness moderate, variable spanwise 0.18-0.12 providing balancing apparatus for a small value of the lift coefficient C _y = 0.2, corresponding to the maximum aerodynamic efficiency. An air inlet is formed of two parts with the edges parallel to the edges of the wing and its channels have a curved axis, the flat nozzle is manufactured with curved guides shielding turbine engine in the rear hemisphere, the edge of the nozzle are also parallel to the edges of the wing. The utility model is aimed at reducing the radar visibility and improved apparatus for balancing angle of attack corresponding to the maximum value of aerodynamic quality.
