Strelchenko E. Determination of safe shutdown of the oxidizer-rich stage combustion liquid rocket engines at full propellants depletion from launch vehicle tanks

The object- the oxidizer-rich stage combustion liquid rocket engine(LRE);the aim-the improvement of the liquid rocket engines safe shutdown method at full propellant depletion from launch vehicle tanks; the methods- the experimental research of a serial LRE shutdown with dynamic simulation of the full propellant depletion,method of statistical data processing for analysis of the test result and inaccuracies estimation, the experiment-calculated determination methods of the threshold continuity analytical dependences and the general selection criteria of the engine control parameters; the novelty - the new general selection criteria of the engine control parameters are formulated, the new threshold continuity analytical dependences are obtained, the LRE safe shutdown method is improved;the resuts- the payload increasing for Zenit-3SL LV by 48,5...100 kg; the branch - rocket engineering
