摘要

A multistage rocket is considered, made according to the model: the central block (last stage), to which four side blocks (boosters) are connected in parallel. The paper assumes a linear dependence of the mass of the fuel tank block on the initial volume of the fuel in the tank, and the mass of each engine is assumed to be proportional to the initial mass of the rocket. It has been shown that the use of boosters with different fuel reserves, which are separated as they burn out, makes it possible to increase the delivered payload with minor design changes compared to the use of four identical boosters. The increase in the mass of the rocket payload has been estimated for several variants of using boosters with different fuel reserves.
