Purpose: This study proposes the main sources of uncertainty and uncertainty analysis of a measurement system of insensitive munitions tests. Methods: We established the mathematical model for calculating measurement uncertainty of insensitive munitions tests, conducted experiments for calculating uncertainties of dynamic sensitivity and overshoot value, and estimated the distributions of uncertainty factors. Results: The measurement uncertainty calculation methods are presented, which include experimental data processing methods for calculating uncertainties of dynamic sensitivity and overshoot value. Conclusion: The measurement of explosion pressure in insensitive munitions tests is an important issue to the reporting test results and classifying reaction types. The more efforts to ensure the reliability of the insensitive munitions tests results are required.

With the advent of low cost, miniature and high-g hardened inertial sensors and actuators, many kind of smart munitions are becoming practical such as 1D or 2D TCM, SFM, Range Extended GPS guided munitions and so on. They have more complicated trajectory control algorithm than conventional munitions'. Therefore it is necessary to study the complicated operation algorithm of smart munitions with M&S in advance of developing them. The purpose of this paper is to introduce a practical M&S method to study an operation concept of smart munitions using PRODAS and Matlab.

We have developed a weapon effectiveness evaluation model for top-attack smart munitions(WEEM/TASM), which is a many on many Monte Carlo Model evaluating the effectiveness of top-attack smart munitions against armoured ground vehicles. In this model the battle is reduced to a one-sided battle situation in that the target vehicles are regarded as being stationary and passive. It can simulate the whole attack process of smart munitions from firing artillery dispenser to sensing and hitting processes after dispense. It can also calculate the probability of kill of each target and the numbers of rounds required to fulfill the degree of damage in statistical manners. In this paper, we describe the basis for our design concepts reflected in the model to simulate the weapon effectiveness of top-attack smart munitions and provide simulation results for an example case.

Our government has been continuously making an effort to improve safety management and prevent accidents in small-to-medium sized enterprises, but the accidents are still happening. Since there hasn't been a study on the actual state of safety management for the munitions manufacturing industry so far, this paper aims to investigate and analyze the actual state of the munitions manufacturing companies in Kyung-In area and it also shows the countermeasures of improvement.

With the development of micro electronic circuits and optical equipment, the demand for developing smart munitions with the ability to autonomously search for and attack targets has increased. Since the electronic components within smart munitions are affected by high temperatures, pressure, and impulsive forces upon the combustion of gunpowder, stability and reliability need to be secured for them. Securing those stability and reliability requires soft recovery system which can decelerate smart munitions. A theoretical analysis of flow is performed for the secure recovery of bullets on the basis of Navier-Stokes equation for compressible fluids. The inner pressure on a pressure tube, the speeds of bullets, and the deceleration of munitions are calculated theoretically. Theoretical results are compared with the data from the experiment with soft recovery system set up at the laboratory.

예기치 않은 외적인 자극에 의한 사고를 막기 위하여 에너지 물질을 함유한 전술 유도무기의 위험성을 감소시킬 필요성이 증대되어, 유도무기 둔감화에 대한 연구가 미국과 나토에서 1980년대 후반부터 활발히 시작되었다. 로켓모터의 둔감성능을 향상시키기 위해서는 추진제를 비롯하여 로켓모터의 모든 부품들이 적절한 조합으로 각각의 특성을 살려 둔감성능 향상에 도움이 되도록 설계되어야 하며 각각의 부품이 어떤 역할을 하는지 이해하여야 한다. 고체 추진기관 둔감화에 필요한 중요한 역할을 하는 구성 요소는 추진제, 연소관, 점화기 및 완화장치 등이 있다.

현대의 무기체계는 새로운 전쟁양상의 변화와 첨단 과학기술의 급격한 발달로 인하여 체계가 복잡 및 다양해지고 있으며, 무기체계의 운영 및 관리를 위한 군수비용의 급격한 증가의 양상을 보이고 있다. 또한 정부의 창조경제 수행방안으로 군의 군수비용을 최소화하기 위한 방안에 대한 적극적인 검토가 요구되고 있다. 이에 본 연구에서는 군수비용 절감을 위하여 첫째, 군수품의 분류기준, 관련 규정 및 제도, 장비정비정보체계에 대해서 분석 등을 통한 군수품 관리의 문제점을 도출하였다. 둘째, 도출한 군수품 관리 문제점에 대한 개선방안으로 실명제 및 책임제 군수관리의 필요성과 운영방안, 정비지시서 상태분류 기준 세분화 적용방안을 제시하였으며, 적용에 따른 기대효과를 분석하였다. 마지막으로 IT기술 중 CBM를 활용한 품목별 제원관리 및 기록체계를 구축 할 수 있도록 총수명주기체계관리(TLCSM)를 현 군에서 운용 중인 장비정비정보체계와의 연동할 수 있는 시스템 구축 방안을 제시하였다. 이와 같이 제시한 방안을 적용하게 된다면 군수행정의 오류방지, 단순화 및 신속화, 군수품 관리에 대한 신뢰성 향상 및 예산절감 등의 효과가 기대된다.
