Analytical study of the FV atmospheric flight dynamics under propulsive engine control

A mathematical model of the atmospheric flight of a flight vehicle being controlled by small propulsive engines is presented. The analytical solutions of differential equations are obtained for the approximate calculation of kinematic parameters in the steady-state motions. The flight dynamics and control are studied under conditions of nose lift and diving. The results are suitable for the choice of design FV parameters and synthesis of onboard algorithms of control and parametric identification.
