수중에서 추진되는 초고속 로켓 모터에 적용이 가능한 해수반응 금속연료 (Hydro-Reactive metal Fuel, 이하 HRF) 추진제는 연료의 적재량을 증가시키기 위해 채용하는 추진제이다. 하지만, 현재까지 HRF 추진제에 대한 연소속도 측정 기술 개발에 대한 연구는 미비한 상태이다. 본 연구팀은 연소 속도를 측정하는 기법들 중, 한 번의 실험으로 압력 변화에 따른 연소속도 측정이 가능한 초음파 법을 개발하여 고체 추진제의 연소속도를 측정하고 신뢰성을 검증하였다. 본 논문에서는 기 개발된 시스템을 이용하여 HRF 추진제의 연소 속도를 측정하였다. Hydro-Reactive metal Fuel (HRF) which has more fuel than general solid propellant reducing oxidizing agent is suitable for ultrahigh speed rocket motor in the water. However, burning rate of HRF has not been studied yet. Through the earlier studies, we established ultrasonics measurement system measuring burning rate of solid propellant as a function of pressure in a single test and verified its reliability. In this paper, we will measure burning rate of HRF using ultrasound with previous development measurement system.

Quality management is an activity that is continuously managed to meet quality requirements. This paper aims to improve quality through the development of the quality management system in integrated product support. First, the scope of the quality target is identified based on the quality control gate. After that, a plan to carry out improved quality activities was proposed by assigning responsibility for quality review, agreement, and approval of consumer and development agency. Using this quality management system, measurements of improvement are clearly identified. Also, product, processor, and person centered quality control can be performed through step-by-step Q-gate.
