Abstract

The paper considers the problem of determining the optimal control law for the thrust vector of an active-reactive type penetrator designed for penetrating and studying the subsurface layer of celestial bodies. Optimization of the thrust vector control for the active-reactive type penetrator was conducted. A law for the variation of the thrust of a solid-propellant rocket engine was derived, represented as a quadratically increasing dependence with low curvature. The calculation of the mass variation function for the active-reactive type penetrator is presented. The formulated conclusions can serve as a basis for justifying the operation mode of the solid-propellant rocket engine of the active-reactive type penetrator for movement in dense soils.
