FIELD: test benches of artillery barrels, applicable for follow-up of the parameters of "knife" twist of jet projectile launchers from polymeric tubes. SUBSTANCE: the test bench has a fixed bed for attachment of the launching tube or its fragment, flange and a rotary disk. The rotary disc is provided with a simulator of the jet projectile with obliquely set knives, that is positioned in the mating square window of the rotary disk. The rotary disc is coupled to the adjusting yoke of the braking device including a brake drum secured on the flange that is provided with a pair of reactive strain rods. The rotary disc is provided with a pair of calibrating force exciters with devices for measurement of the simulator displacement and its force. EFFECT: enhanced reliability of test results approximate to the natural ones. 2 cl, 5 dwg
