The stepped control of intraballistic performances a solid-propellant rocket engine by change of combustion charge surface

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
