This paper continues previous work and completes the design of the rocket's orbits which can hit the moon. In this paper, the relations between the initial conditions and the positions on the moon's sphere of influence are imperoved, based on the double two-body problem. Further, the effects of other disturbing factors (solar and planetary gravitation, drag of atmosphere etc,) on successfully hitting the moon, except lunar gravitation and first order terms of the terrestrial field of gravitation are discussed....

This paper continues previous work and completes the design of the rocket's orbits which can hit the moon. In this paper, the relations between the initial conditions and the positions on the moon's sphere of influence are imperoved, based on the double two-body problem. Further, the effects of other disturbing factors (solar and planetary gravitation, drag of atmosphere etc,) on successfully hitting the moon, except lunar gravitation and first order terms of the terrestrial field of gravitation are discussed. The results show that these factors can be neglected. In the last part, the deflections which are produced by the errors of initial values are studied, from which,the allowable maximum errors of the initial values are calculated.

A preliminary analysis for the dynamic Characteristics of a variable-thrust rocket engine control-loop system under investigation is presented.Employing the testing results and with the aid of equivalent approach,the mathematical descriptions for the main links of such a system are introduced,and then the analytical models and impulse transfer functions of this system are given. According to the calculation results,the effect of design parameters on the stability, the static error and the time response is analysed.In order that the analysis is based on the reliable initial data,the experimental method for obtaining these data is illustrated briefly in the last section.
