Abstract : There are investigated questions of optimum pulse control of the spatial orientation of an axially symmetric space vehicle (SV). It is assumed that control of the SV is carried out by two pairs of control jets (CJ), one of which is fastened in the vehicle and creates a moment about the axis of symmetry, and the second pair is fixed in a cardan suspension and can create a moment about any axis orthogonal to the axis of symmetry of the apparatus. Optimum control of orientation of the axis of rotation which is the axis of symmetry of the SV is found. Conditions are determined under which control of orientation can be carried out by one pair of CJ fastened in the vehicle. Control is optimized of orientation of the SV rotating about a principal axis of inertia which is not the axis of symmetry. Optimum control of the spatial orientation of an axially symmetric SV is investigated in general. (Author)
