Abstract

Environmental problem of the solid propellants is an issue of growing importance in solid rocket. For examples, ammonium perchlorate (AP) as an solid propellants oxidizer could create a poisonous gas and atmospheric pollutions, such as HCl. Among the several oxidizers, N-guanylurea dinitramide (GuDN) is an effective candidate substance for eco-friendly oxidizer, which has high performance, pressure exponent, and eco-friendly smog during combustion for solid propellant of gas generator. In this paper, the theoretical analysis of characteristics as a gas generator propellant, propellant manufacturing processability, propellant hardness properties and combustion characteristics were studied.

고체 추진제의 환경적 문제는 고체 로켓에서 중요한 이슈로 부각되고 있다. 예를 들어 고체추진제의 산화제인 ammonium perchlorate (AP)는 염산과 같은 독성 가스와 대기 오염을 발생시켜 환경적 문제를 야기한다. 산화제 중 N-guanylurea dinitramide (GuDN)는 높은 성능과 압력 지수를 가지고 있으며, 가스발생기 추진제에서 연소하는 동안 친환경적인 연기를 배출하는 성질을 가지고 있기 때문에 환경친화적으로 효과적인 후보 물질이다. 본 논문에서는 가스발생기 추진제로서 특성에 대하여 이론적 분석, 추진제 제조공정성, 추진제 경도 특성 및 연소특성에 대하여 연구하였다.
