Basic TTD - machine gun exists in two versions (I do not know the difference except the weight, it seems that they have different lengths of the main and some differences on the holster)
The propulsion of the weapon is the pressure of the gases taken from the barrel.
Tensioning is electropyrotechnic, three pyropatrons PPL.
Triggering is electromechanical. The start of the barrel block when the firing is interrupted is ensured by a spring placed between the barrels.
The cartridges have a classic mechanical match.
The weapon is designed as a weapon for Mi-24 helicopters in the USPU-24 shooting range and for the armament of Mi-24 and Mi-8/17 series helicopters in the GUV-8700 suspension container (9A669)
