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.

U. S. and NATO allies have recently increased their emphasis on reducing the hazards of tactical munitions that contain energetic materials and actively started many investigations on Insensitive munitions(IM) of missile propulsion. All subcomponents of rocket motor should be properly designed and understood to increase IM properties. Insensitive propellant, motor case, ignitor and mitigation devices are important components of IM technologies of rocket motors.

The cost of preparing munitions in weapon system operation and management has been rapidly increasing and current weapon systems have become complicated and diverse due to new warfare pattern changes and the rapid growth of advanced scientific technology. Moreover, as a part of the execution plans of creative economics, the Korean government is actively reviewing how to minimize the costs of preparing munitions. Accordingly, this study derived the issues of munitions management for decreasing munitions preparing costs. First, the issues of munitions management were introduced through review and analysis with respect to the munitions classification criteria, regulations and systems, and equipment maintenance information systems. Second, we proposed the application and necessity for the real-name system which is responsible for munitions management and the fragmentation of the maintenance instructions status classification criteria.. Also, we were analyzed that the effects depending on the application. Finally, we proposed that the linkage system which is currently military active with equipment maintenance information systems as well as the total life-cycle management system (TLCSM) improvements to the itemized data and records management system by utilizing IT technology CMB that must be done in order to improve the issues.
