The paper investigates the individual and combined effects of disturbance factors including thrust misalignment, the offset of the centre of gravity and misalignment of the principal axes of inertia on falling point distribution of a type of unguided rocket (fin-stabilized rockets with single-stage solid-propellant rocket engines). The mathematical model used in the paper is developed from an available rocket motion model and solved for a representative rocket which is BM-21 rocket. The obtained results show dependencies of falling point deviation on disturbance parameters. These dependencies agree with the standard data given in the firing table; in addition, they are fuller and more insight ful than the previous research.
