FIELD: aviation.
SUBSTANCE: invention relates to the creation of multirotor high-speed combined helicopters (MSCH). An MSCH has propulsion-lift rotor systems at the wing tips, engines interconnected by synchronizing shafts and laid in the wing and rotating propellers and rotors. The MSCH is designed on the basis of various thrust of different-sized rotors (VTDR) and has two smaller rotors installed on one-piece rotary arms of V-shaped horizontal canard and two larger lifting rotors mounted in such a way that their blades planes of rotation are located between spanwise different biplane wings, forming with their internal sections in a front view sort of the left and right trapezoidal conduits and fixed to the output shafts of cantilevered gears, each of which is placed in a lower droplike fairing on the tip of an arrow-shaped front wing.
EFFECT: reduction in the required power for the longitudinal balance while hovering and improved longitudinal controllability.
