FIELD: transportation.
SUBSTANCE: transport-combat helicopter comprises fuselage, lifting propeller with blades made of polymer composites, four-blade X-shaped antitorque rotor, twin-engined power plant with dust protection device, helicopter control system, screen-exhaust unit, nonretractable landing gear, nondetachable movable gun. The system is provided with hydraulic stop unit. Hydraulic stop unit interacts with upper angular walking beam of longitudinal control guide. Therefor magnet crane of hydraulic stop unit switching on is connected to airspeed signalling device and to micro switch which rod is kinematically connected with upper angular walking beam of lifting propeller general pitch control line using double-arm lever with roller and profile collar.
EFFECT: improvement of transport-combat helicopter reliability.
