FIELD: engines and pumps.
SUBSTANCE: bench for static tests of rocket engine housing includes power rack with attachment elements of the housing under test, device for creation of pressure inside the housing, and piston connected to the power rack. Piston is hinged to power rack through a rod and located in nozzle flange of the housing. Piston rod is installed at acute angle to axis of nozzle flange, hinged to the piston and can be adjusted as to the length. On power rack there is a row of holes to install the rod hinge.
EFFECT: improving test accuracy owing to development of lateral force and bending moment on nozzle flange during loading of rocket engine housing with internal pressure.
