FIELD: aviation.
SUBSTANCE: invention relates to the field of aviation, particularly to the rotary-winged aircraft designs. Rotary-winged aircraft (20) of hybrid type comprises rotor (1), at least two traction elements (2, 2'), respectively installed, each, on half-wings (3, 3') arranged symmetrically on both sides of the middle front-rear XOZ plane, horizontal tail unit (8) located in rear area of above rotary-winged aircraft (20) on both sides from said middle front-rear plane XOZ, and two keels (21, 21') located respectively on both sides of said middle front-rear XOZ plane. Each of said two keels (21, 21') contains lower left/right keel blade (22, 22') located under said horizontal tail unit (8), and upper left/right keel blade (23.23)') located above said horizontal tail unit (8).
EFFECT: possibility to reduce and even eliminate vibration problems, characteristic for tail fins in form of inverted U.
