ON THE STABILITY OF THE STABILIZED MOTION OF A CARRIER ROCKET WITH A LIQUID-PROPELLANT JET ENGINE AND AN ONBOARD DIGITAL COMPUTER IN THE STABILIZATION LOOP

Abstract

The problem of choosing the values of the variable parameters of the digital stabilizer of the cosmic stage of a carrier rocket with a liquid-propellant jet engine and an onboard digital computer in the stabilization loop, which ensures stable movement of the stage along the entire active section of the flight trajectory, is considered. The effect of the stabilizer quantization period on the stability region of a closed-loop stabilization system is considered. It is recommended to choose the intersection of stability regions corresponding to uniformly distributed moments of time along the active section of the stage flight trajectory as acceptable values for the variable parameters of the stabilizer of a non-stationary stabilization object.
