Efficiency of a launching booster multinozzle configuration for rockets with out-of-round asymmetrical nozzles

The results of analyzing ways of improving the total thrust impulse for the launching rocket boosters under severe limitations of overall dimensions are presented. Comparative performance evaluation of the launching boosters manufactured by the classical single-nozzle and multi-nozzle configurations is given. It is shown that the use of the multinozzle configuration with the out-of round asymmetrical nozzles is rational.
