Abstract

One of the most frightening aspects of weapons of mass destruction (WMD) is their ability to cause death in very small quantities without being visible to the public. The military authorities are making considerable effort to ensure the survivability of the combatants in the event of NBC(Nuclear, Biological and Chemical) contamination. Therefore, in this study, modules were developed for the measurement of the positive pressure and for the detection of the chemicals used for the control of the various shut-off valves used in an NBC shelter. In addition, a high performance gas tight shut-off valve was developed that can overcome the disadvantages associated with manual manufacturing, such as the occurrence of defective products and high manufacturing cost. By applying the positive pressure measurement and chemical detection modules, this valve was able to be used to control the facility. The developed gas-tight shut-off valve maintained airtight characteristics at a pressure loss of 28[Pa] at the prescribed wind velocity and an internal pressure of 30[kPa]. It is expected to be possible to control the gas-tight shut-off valve through the remote measurement of the positive pressure, thereby ensuring the foreign independence of import substitution and defense related technology in the future. In addition, by installing these valves in all of the intake ports or exhaust ports connected to the outside of the NBC shelter, it is possible to prevent the damage resulting from the rapid inflow of the storm pressure caused by conventional weapons and nuclear explosions, thereby protecting the people and equipment in the shelter.

대량살상무기를 이용한 전쟁 발발 시 가장 위협적인 것은 일반적으로 눈에는 보이지 않으면서 극소량으로도 사망에 이를 수 있다는 것이다., 군 당국은 화생방 오염상황 발생 시 전투원의 생존성을 보장하기 위해 개인 및 화생방대피분야에 대해 상당한 노력을 투입하고 있다. 따라서 본 논문에서는 화생방 방호시설에 사용되는 각종 차단밸브의 제어에 이용되는 양압측정을 위한 모듈과 화학탐지 모듈을 개발하였다. 또한, 수작업에 의한 제조 공정으로 품질의 균일성이 부족하고, 불량품 과다 및 제조 원가가 높은 단점을 개선할 수 있는 고성능 가스차단밸브를 개발하였으며, 여기에 양압측정 및 화학탐지 모듈을 적용하여 화생방방호시설의 제어에 사용하였다. 개발된 가스차단밸브는 규정풍속에서의 압력손실 28[Pa] 및 내부압력 30[kPa]에서 기밀특성을 유지하였다. 원격에서 측정된 양압에 따라 가스차단밸브의 제어가 가능하므로 향후 수입대체 및 국방관련 기술의 대외 독립성 확보가 가능할 것으로 기대된다. 또한 재래식 무기 및 핵폭발에 의한 폭풍압의 급격한 유입으로 인한 피해를 예방하기 위하여 화생방 방호시설의 외부와 연결된 모든 흡기구나 배기구에 설치하여 시설내의 인명 및 장비 등을 보호할 수 있다.
