Abstract

Water rocket is a pressurized liquid propellant rocket that shares the same basic principles of space launch vehicles. Water rockets can be used as an engineering educational material for the liquid rocket principles and the launch vehicle systems, far beyond the scope of K-12 level science education. In this paper, the principles and theories of water rocket propulsion and flight dynamics was investigated at the level of undergraduate rocket engineering classes. Also, the system level design and operation of water rocket is summarized by including the components of launch vehicle, launch pad, payload and recovery as well as altitude measurement methods.

물로켓은 우주발사체와 동일한 기본원리를 가지는 가압식 액체추진제 로켓이다. 물로켓은 청소년용 과학교육 교보재 수준을 훨씬 넘어, 대학 수준의 액체 로켓 및 발사체 체계 공학 교육의 도구로 활용될 수 있다. 본 논문에서는 물로켓의 추진 및 비행 원리와 이론을 대학 학부의 로켓 공학 교육 수준에서 고찰하였다. 아울러 발사체와 발사대, 탑재체, 회수 및 고도 장치와 방법 등 체계 수준의 물로켓 설계와 운영에 대한 사항들을 정리하였다.
