FIELD: engines and pumps. ^ SUBSTANCE: rocket engine test device includes engine housing and a stock with an eye lug and nozzle throats, which are located at its bottom. Stock is installed coaxially to the housing, and nozzle throats are located symmetrically relative to the stock. Plugs are installed in nozzle throats with possibility of axial movement. A balance-beam is hinged in the stock eye lug, and the rods connected to the balance-beam are arranged on plugs. ^ EFFECT: invention ensures more precise imitation, during the test, of stress and strain state of the engine design, which appears during its operation. ^ 2 dwg |
