FIELD: aviation.
SUBSTANCE: two-position electrothermomechanical locking carabiner for parachutes with adjustable descent resistance contains mutually rotating elements. According to the invention it includes a shaft to which a bottom lever is fixed via a splined or movable key joint by means of an electrothermomechanical lock. The middle lever is secured in the middle of it on a thrust bearing. And the upper lever is fixed to the top of it on a thrust bearing by means of an electrothermomechanical lock. Wherein the upper and middle levers are connected through a splined or movable key joint and in both cases the electrothermomechanical lock is a split cylindrical bushing entering the shaft groove and wound by a wire which is attached to a segment of the split bushing, using one or two loops of nichrome wire, to which managed electrical voltage is supplied.
EFFECT: reliability increase.
