헬기 장갑소재의 요구방호수준에 관한 연구 -국방경영의 관점에서-

Abstract

In modern warfare, the concept of combat line is getting expanded and has affected weapon systems. The Survivability of helicopter has been originally vulnerable due to low altitude operation and limitation of maneuverability. But, we expect that the vulnerability increase in changing warfare. Developed countries has already developed the upgrade model in order to increase the protection level of helicopter. But, the application of protection material is closely connected to cost of weapon acquisition and maintenance. The objective of this study is to provide the procedure to calculate the thickness of helicopter’s armored material according to the desired protection level. This study provide the level of protection material under development on international standards that has applied to protection of helicopter. The thickness of protection material is inversely proportional to cost of acquisition and maintenance, so we should apply minimum protection thickness that meets the desired protection level for effective military management. In experimental approach, we have suggested experimental method for protection level in international standards(STANAG 4569, NIJ, etc.). In theoretical approach, we proposed the process to calculate thickness of protection material which is a type of high hardness steel, which the desired protection level is 99% using 0.3 inch diameter bullet at 100yards. The study is meaningful to provide an approach to set the optimized level of protection for weapon system and to analyze the acquisition alternatives to estimate the acquisition cost of weapon system. And further defense manager can refer to the study results to manage the total ownership cost including operational & maintenance cost as well as defense acquisition cost.
