METHOD FOR CONTROL OF STARTING sustainer engine upper stage and team 'TROUBLE upper stage' on a site DORAZGONA

摘要

A method for controlling start the main engine booster and forming command "Emergency booster" on site dorazgona consisting in that, after separating the upper stage of a rocket - carrier in a raised flight mission times include at specified in the flight mission interval pulse correction motors time compression of the fuel in the tanks, trigger boosters, calculating the apparent acceleration nominal value of the main engine, determine the minimum allowable level of the apparent acceleration, f Filtering measured values ​​of the apparent acceleration, after a fixed time interval after the command to start the main engine compares the magnitude of the apparent acceleration of work propulsion engine with a minimum acceptable level, if it exceeds - form characteristic "Starting main engine" and continued refinement of the control sequence diagram at the site dorazgona, when exceeding the allowable rate consecutive number of recorded cases in which the current value of the filtered apparent acceleration is below the straight fittings for the level, form the characteristic "Do not start the main engine" and command "Shutting down the main engine, characterized in that after the formation of feature" Do not start the main engine "preserve orientation upper stage is zeroed filtered value of the apparent acceleration, is changed to the set value specified in the flight mission times when power correction pulse and the main engine, while achieving these moments include appropriate motors controlled by the magnitude of the apparent acceleration of slave
