FIELD: aircraft engineering.
SUBSTANCE: proposed method consists in creation of counteracting torque by exhaust gas flow thrust reactive forces as reactive jets of helicopter gas turbine driven by separated power portion generated by engine gas generator along with their crosswise-tangential feed into supporting airflow created by rotor. Rotor torque is developed by rotor drive turbine from another portion of kinetic power generated by gas generator along with air intake from rotor central zone, less active one, or from outside of rotor action zone. Compensation torque is controlled by varying the resultant of forces of reactive jet at their counteraction without changing the increased reaction of support flow to the rotor, or the degree of redistribution of kinetic flow of the engine by conversion of said flow into reactive jets at bypassing the rotor drive turbine with preservation of invariable rotor thrust.
EFFECT: increased lift.
