The paper studies the efficiency of new static analysis techniques for electrohydraulic control actuators of rocket packs, namely, the computational technique for their static patterns (speed and power, or torque) with a given accuracy and in minimal time. The proposed techniques are based on numerical integration of the nonlinear differential equations systems in dynamic mathematical models of the control actuators of rocket packs. They have two main cycles: a command input and time. According to these techniques, the process of numerical integration of nonlinear differential equations in dynamic mathematical models of the control actuators, with each fixed value of the command input, continues until the average values of the linear (angular) speed of the control actuator output device are rather constant, while calculating either the speed or power (torque) pattern. The latter is produced by the control actuator output device. It is shown that such techniques are applicable for the static analysis of the control actuators with a changeable structure.
