LIQUID-PROPELLANT ROCKET ENGINE TEST STAND Russian patent published in 1998 - IPC

FIELD: test stands for testing liquid-propellant rocket engines observing criteria of hydrodynamic similarity of lines delivering propellant components to liquid-propellant rocket engine. SUBSTANCE: test stand includes service tanks 1 which are connected with separating reservoirs by means of service lines 2. Separating reservoirs 3 are connected with booster reservoir 4 by means of pipe lines and with liquid-propellant rocket engine 4 under test by means of starting lines 5. Separating reservoirs are provided with cut-off valves 7 with seats 8 which are tightly connected with inlet of starting lines. Valves drives 9 are located on the outside of separating reservoirs. Valves and their drives are interconnected mechanically by means of links 10 passed through holes fitted with seals 11 in walls of separating reservoirs. Service lines and compressed gas pipe lines are fitted with cut-off pneumatic valves. EFFECT: enhanced efficiency and reliability. 1 dwg
