Abstract
Results on flight dynamics of an axisymmetric vehicle with a control action in the form of gas jet ejection are reported. The differences in the flight trajectories with and without allowance for the pressure redistribution over the vehicle surface due to transverse gas jet ejection are considered and analyzed. Targeted software is developed on the basis of the equations of motion of a material point in space and rotation of the flying vehicle around its center of mass. The influence of the pressure redistribution over the axisymmetric vehicle surface owing to ejection of a lateral transverse gas jet on the flight trajectory and on the rate of vehicle deviation in terms of the yaw angle is demonstrated.
