Abstract:

The book discusses the differential equations of the perturbed motion of a rocket for three different dynamic models an ideally rigid body an elastic inhomogeneous rod a rigid body with cavities partially filled with liquid. In the study of the dynamic characteristics of the rocket, the oscillations of liquid in tanks were replaced by the oscillations of mathematical pendulums. Results are given of an experimental investigation of the fuel oscillating in tanks. A presentation is made of the methods of determining the modes and frequencies of the natural vibrations of the fuselage. A determination is made of the amplitude-phase frequency characteristics of the rocket, and of those features of the characteristics that are due to the fuel oscillating in tanks and the elastic vibrations of the fuselage. A stability analysis of rocket motion leads to a formulation of additional requirements on the frequency characteristics of the control system and on the location of the gyroscope along the fuselage. Attention is given to certain methods of stabilizing the oscillating motion of fuel in tanks as well as the elastic vibrations of the fuselage. Author
