Abstract

In the article the stepped control method of intraballistic performances the
solid-propellant rocket engine is presented by change of combustion charge surface.
The optimum number of control intervals is determined. The control
methods providing with stability of any one intraballistic performance are considered
and is shown, that in the view of providing with parametric reliability the
control method based on minimizing deviations condition of all intraballistic performances
is much more effective.
