FIELD: engines and pumps. ^ SUBSTANCE: invention relates to bench equipment designed for hydraulic testing of casings of solid-propellant rocket engines (SPRE) for internal pressure. The bench, according to the invention, comprises an unloading device of a rear flange, which comprises a cylinder, which is rigidly connected to the rear flange of the body and the piston, having a support joined to a reinforced floor of the bench. At the same time the cylinder of the unloading device is installed outside the casing, and the diameter of the unloading device piston is equal or less than diameter of the rear flange throughput section. ^ EFFECT: making it possible to do a test with simulation of rocket casing loading in process of charge formation. ^ 2 dwg |
