FIELD: aviation. SUBSTANCE: drives of parachute lines with pulleys and stops for lines of each parachute are mounted between center of mass of helicopter and plane of rotation of its blades. At least three parachutes are deployed beyond case of helicopter and parachute lines are placed on stops; drives of parachute lines are located around center of mass of helicopter and after complete extraction of parachutes, lines are heaved in by means of drive in order to enhanced aerodynamic coupling of parachute canopies with incoming flow of air.
