Simulacija rafala višecevnog bacača raketa

Abstract

U radu je predstavljena procedura za efikasno simuliranje rafala višecevnog bacača raketa i uticaja rakete na ostale delove sistema. Analizirano je ponašanje rakete u odnosu na referentnu idealnu trajektoriju, koju generiše idealna raketa. Kvalitet rafalne vatre je rasturanje padnih tačaka na cilju što je mera preciznosti i tačnosti. U radu je razmatran samo uticaj preciznosti, tj. rasturanja raketa, pri čemu se smatra da je greška tačnosti zanemarljiva. Na taj način identifikuju se sopstveni (municijski) uticaji na fenomen rasturanja trajektorija. Rasturanje na cilju upoređeno je sa rasturanjem na kraju aktivne faze u takozvanim estimatorskim koordinatama (detektorskoj ravni) i biće utvrđena njihova korelacija.

This paper presents a procedure for an efficient simulation of MLRS barrage fire as well as of the effects of rocket parameters. The rocket behavior will be analyzed with reference to an ideal trajectory generated by an ideal rocket. The quality of MLRS fire is expressed through dispersion of impact points in the target area thus representing precision and accuracy. This work assumes absolutely correct accuracy and concentrates primarily on the effects of precision i. e. on the dispersion of rockets. Other types of effects on rocket dispersion, such as those of atmosphere, launching, etc. are neglected. The ammunition effects on the trajectory dispersion will be thus identified. The dispersion in the target area will be correlated with the dispersion of trajectory points at the end of the active (rocket motor burn out) phase.
