Abstract
This study develops a method for structural and parametric optimization of combined ballistic launchers for the selected criterion with restrictions. Mathematical modeling of intrachamber processes is carried out in the framework of a unified approach based on quasi-one-dimensional continual media equations. Three types of media are considered: gunpowder, deformable piston, and gas. For structural and parametric optimization, a genetic algorithm is used. Crossover and mutation operators have been developed for the structure and parametric optimization of combined ballistic launchers as a class of objects. Operating with a variable set of parameters is the feature of the algorithm. A parallel implementation of the genetic algorithm with the rejection of “generations” was used. A model problem was calculated as an example of the developed algorithm operation. As a result, one can observe the evolution of the ballistic launcher structure by the rate of muzzle velocity.
