摘要

对于一个具有可变成分的空间体，假定了利用内能的机制所产生的受控(可变)质量放电速率。在这个假设的基础上，在狭义相对论中推导出了无外力的动力学方程，它的解使得在整个运动速度的物理范围内研究关键的火箭动力学和天体物理学问题成为可能。

Equations of Motion of a Space Body at a Variable Velocity of Discharging Combustion Products in the Prerequisites of the Special Theory of Relativity

A controlled (variable) rate of mass discharge generated by the mechanism of using the internal energy is postulated for a space body with variable composition. Based on this postulate, equations of the dynamics without external forces are derived within the special theory of relativity, the solution of which makes it possible to study crucial rocket dynamics and astrophysics problems over the entire physical range of speeds of motion.

期刊介绍： Doklady Physics is a journal that publishes new research in physics of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
