Scientific paper
The paper examines the speed-optimal acceleration of a spacecraft with a low-thrust electroreactive engine moving at parabolic velocity in a central gravitational field, with constrained angular velocity of the thrust vector. The design of the optimal control mode is reduced to optimal control of the angular velocity and based on the solution of a variational principle with the aid of the Pontryagin principle. The variational principle is reduced to a boundary value problem for a system of eight first-order differential equations on the basis of an analysis of necessary optimality conditions.
