Abstract

U radu je predstavljen integralni pristup istraživanju parametara projektovanja raketa sa aspekta usaglašavanja ograničenja proisteklih iz zadataka mehanike pri posebnim uslovima gađanja balističkih ciljeva koji nameću različite konstruktivne kompromise...

An integral approach has been presented on the research of missile design parameters from the aspect of harmonizing the limitations arising from the tasks of mechanics under the special conditions of hiting ballistic targets that impose various constructive compromises. Shooting target was analyzed for the most complex procedure of defense against ballistic targets. Basis on previous, it was establish criteria for require missile impact parameters and its ideal limit capabilities. The required normal acceleration, miss distance and control effort for each of the threshold missions are estimated. Based on the established criteria, a further aerodynamic design procedure is given, which is manifested through the selection of body geometric and aerodynamic performances, as well as appropriate control concepts for the requirements of the required maximum normal acceleration in the conditions of threshold flight missions. The synthesis of the autopilot of the vertical launch of the missile was performed, as well as the determination performances of the selected type of thrust vector control system and aerodynmaics for the purpose of hybrid control analysis. In particular, the propulsion performance assessment was carried out to integrate total flight and impact assessment of axial acceleration during the initial phase after vertical launch. The results of the influence parameters on the dynamic characteristics of the vertical launch of the missile in the active phase for hybrid control are presented. A mathematical model of possible use of a warhead for direct hit by an explosive-formed projectile was performed. Design approach and application of explosively-formed projectiles is presented as a potential useful warhead based on the adopted analytical and numerical methods.
