The System Engineering(SE) and the Earned Value Management System(EVMS), as parts of the scientific project management methodology, have been applied to Surion Helicopter R&D Program. The concept and application process of SE methodology, requirements management and applications output by DOORS program are described in this study. The concept and application process of EVMS, analysis results of schedule/cost variance for Surion RF equipment are also discussed in this study. Though the Surion R&D program is still on-going, it is found that the measures of effectiveness of SE and EVMS applications are verified.

The silencer for the medium caliber gun was studied to reduce the propagation of gun-generated noise from the firing test range to the community. Three types of silencer were made to compare the reduction of sound pressure level and the effect of chamber volume and the exit angle to the reduction of sound pressure was considered. The structural analysis and measurement of pressure in the silencer showed that the structure is safe in terms of strength. The increase of recoil force to buffer must be considered in the development of silencer. The hypothesis test on the muzzle velocity for the existence of silencer showed that there are no difference at the significance level of 0.05.

Purpose: The purpose of this study is to escape from the existing defense quality policy focused on government-led quality assurance for mass-produced items and to secure quality reliability of weapon systems through a defense quality policy paradigm shift based on designing a verification systems anchored on reliability through the enhancement of military supply quality control in the development stage, the enhancement of quality responsibility of the manufacturing contractor and other methods. Methods: For the shift to the quality-based defense quality policy, the status and the problems of the status quo are analyzed and the direction of future defense quality policy is suggested based on literature review of the concept of reliability and reliability in the field of defense, on case studies of global corporations and their quality policies, on the background on quality assurance in defense, and on case studies of quality policies in other government organizations, Results: Based on the case studies of quality policies in global corporations and other government agencies, the importance of preventive quality control from the early development stages, quality control based on the reliability of the materials and parts, and shift of the quality policy to a certification system to achieve these objectives were highlighted. Conclusion: To secure reliability of weapon system quality, the quality policy must be shifted to a system focused on reliability-based design and verification and there is a further need to enhance the operational efficiency and capacity of DTaQ based on studies and evaluation of weapon system reliability.

In order for the military organization to be reborn as a high-tech science and technology strong force, science and technology that can be applied to the military is identified at the rapid development of science and technology, This should be quickly applied to military organizations, which is a growing consensus that Defense R&D planning system centered on rioters is needed to quickly acquire advanced weapons systems. In this respect, in order to successfully achieve the current government's defense policy, the high-tech weapons system necessary for national defense is required quicklyIt is necessary to closely examine defense planning, systems, organizations, and functions to develop into a high-tech science and technology military to link from raising to acquiring, and to reorganize the power enhancement and operation system. Therefore, this study proposes a high-efficiency defense operation system that combines advanced science and technology by Korean military organizations through "Defense Innovation 4.0", and we hope that follow-up research will be conducted following this study.

All matter above absolute zero emits thermal energy. Thermal imaging system converts the infrared radiation of a scene into a live picture of that scene : the thermal image is a pictorial representation of temperature differences. This paper has outlined the principles of thermal imaging and has briefly reviewed the history, and the present day and future technology.

Recently, the LISI(Level of Information System Interoperability) model has been used to measure level of interoperability in the Ministry of National Defense. This study is proposed for improvement of interoperability level measurement method. The MND has been devoting a lot of effort to ensure defense weapon system interoperability. They enacted related regulations and developed SITES for measuring the level of interoperability. However, the LISI model has problems with using just only DITA and applying MND-AF based on Architecture development. To overcome these problems, this paper proposes how to apply reference model to LISI Model and how to apply LISI Model to MND-AF architecture development.

This paper includes a study on the performance analysis of SDINS by a simulator using Matlab/Simulink. The performance model is considered gravity and Coriolis force, and a barometer is included to damp down diversity of a perpendicular axis error. Using the simulator, the performance included gyro sensor errors was analyzed in various maneuvering patterns. Also, the performance is virtually presented for the variation of error parameters of gyro and accelerometer under GUI.

This study aims to the increasing the reliability of gun firing system of patrol killer guided missile from failure mode analysis. In order to find out the breakdown parameter, the examination process of the sources of the problems and the quality improvement activities are analyzed with performance testing data. From this study, the rate of operation and the reliability of 76 mm naval guns will be increase. And the result of the study is expected to be used as a reference data in the naval gun firing system for another failure mode analysis.

The Tactical Data Link System(TDLS) is a standardized communication link to exchange and interface positional, situational information, command and control in real time. It has been evalua ted that the link would play an important role for tactical interoperability, situation awareness, and execution of joint operations in the future war. But considering the rapidly changing war situations, even though being admitted the necessity of the TDLS of Army helicopter, one of superpowers in the Army, it is not yet built the detailed operational concept. Therefore, this work presents how to embody the TDLS through the systems engineering approach based on the TDLS operating concept analysis of helicopters-ground units.
