Analiza efikasnosti bojnih glava parčadnog dejstva protiv "mekih" ciljeva
Efficiency analysis of a fragmentation warhead against soft targets
Sažetak
Efikasnost sistema naoružanja se često razmatra sa aspekta unapređenja metoda vođenja i upravljanja, kao i aerodinamike projektila. U ovom radu reč je o istraživanju mogućnosti poboljšanja efikasnosti bojne glave parčadnog dejstva putem unapređenja njene konstrukcije. U cilju povećanja efikasnosti bojne glave protiv mekih ciljeva razmotrene su različite geometrijske konfiguracije bojne glave, različiti položaji tačaka iniciranja, kao i materijal i oblik unapred formiranih fragmenata. Osnovu studije predstavlja numeričko određivanje statičke raspodele vektora brzine generisanih fragmenata. Na osnovu ove raspodele razvijen je novi program koji omogućava određivanje efikasnosti bojne glave. Pokazano je da pomenute promene konstrukcionih parametara značajno utiču na efikasnost bojne glave. Rezultati simulacija se veoma dobro slažu sa rezultatima eksperimentalnog ispitivanja. Novi program za proračun efikasnosti bojnih glava, odnosno ranjivosti ciljeva, može se smatrati korisnim dopunskim alatom za sistemsku inženjersku analizu efikasnosti sistema naoružanja.
Abstract
The efficiency of the weapon system has been usually studied by altering the guidance and control or aerodynamics of the missile. This research investigated methods of enhancing the efficiency of the weapon system against soft targets based on the fragmentation warhead design. Different warhead geometric configurations, initiation points, as well as premade fragment material and shapes have been studied to enhance overall weapon efficiency against soft target. The study considered the static fragment distribution and velocity as the base for the analysis. A new vulnerability code has been developed based on the mean area of effectiveness to prove the study using both simulations and field tests. There were significant improvements on the weapon efficiency by altering the warhead parameters. The simulated results showed good correspondence with the test results. The newly developed vulnerability code can be considered as an additional system engineering analysis tool for the calculations of weapon efficiency.
