METHOD TO CONTROL LAUNCH OF LIQUID PROPELLANT ROCKET ENGINES OF SPACE ROCKET

摘要

FIELD: engines and pumps.;SUBSTANCE: method includes fuel ignition in engine combustion chambers, reaching the mode of the preliminary stage, inspection of operability at this mode and generation of a command to change traction of all engines to the main stage. Simultaneously with inspection of operability at the mode of the intermediate stage they measure angular deviations of swinging parts of all engines from their middle positions. If the measured angular deviation of the swinging part of at least one engine exceeds the specified value, a command is generated to switch off all engines. Otherwise all engines are changed, in case of their operability, to the mode of the main stage. Simultaneously they generate commands of control for swinging parts of engines with account of their measured angular deviations.;EFFECT: increased probability of trouble-free rocket launch.;1 dwg
