Abstract

Solid fuel reacts with an oxidizer during combustion of a propellant to increase performance. Representative solid fuels are aluminum, cyclotrimethylenetrinitramine (RDX) and octahydro-1, 3,5,7-tetra nitro-1,3,5,7-tetrazocin (HMX). During combustion, these compounds generate white smoke by reacting with moisture and produce materials that are harmful to the environment, such as carbon monoxide, carbon dioxide, and methane gas. This study prepared a high-nitrogen-containing energetic material, hydrazinium 5-aminotetrazolate (HAT), which could be applied as a solid fuel. The compound was characterized by nuclear magnetic resonance (NMR) spectroscopy, and a thermal analysis was measured by differential scanning calorimetry (DSC). Also, the specific impulses and volumes of detonation gases were calculated using the EXPLO5 program.

고체연료는 추진제 연소 시 산화제와 반응하여 추진제 성능을 증가시키는 역할을 한다. 대표적인 고체연료는 Al, RDX, HMX 등이 있다. 이들 물질은 연소 시 수분과 만나 흰색 연기를 발생시키고, 일산화탄소, 이산화탄소, 메탄가스 등의 환경유해 물질을 다량 발생시킨다. 이러한 문제를 해결하기 위해 본 연구에서는 고체 연료로 사용 가능한 고질소 에너지 물질인 hydrazinium 5-aminotetrazolate(HAT)를 제조하였다. 분광분석(NMR)을 통해 HAT의 구조를 분석하였으며, DSC를 이용하여 열특성 분석을 하였다. 또한, EXPLO5 프로그램을 이용하여 비추력, 가스발생량 등을 계산하였다.
