FIELD: aviation.
SUBSTANCE: invention relates to aircraft engineering, particularly, to combined helicopters-rotorcraft. Unmanned rotorcraft with transverse position of rotors has separate cruise propulsor, rotors. Movement with forward horizontal speed is provided only due to propulsive force created by sustainer. Rotary rotors feature low peripheral speed of blade ends of about 150 m/s. Main part of lift in horizontal flight, about 80%, is created by wing, and screws supplement remaining lift, about 20%, and perform function of ailerons for roll control.
EFFECT: creation of apparatus for investigation of high horizontal speed limits with rotorcraft of such scheme, confirmation of optimality of selected ratio of contributions of wing and rotors in creation of lift required to maintain stable horizontal flight.
