Alkyl Ammonium Perchlorate가 혼합형 추진제의 연소에 미치는 영향
Effect of Alkyl Ammonium Perchlorate on Combustion of Composite Propellant
HTPB/IPDI/AP 추진제의 열분석과 연소 속도 측정을 통하여 n-alkyl trimethyl ammonium perchlorate(ATAP)의 첨가가 혼합형 고체 추진제의 연소 속도에 미치는 효과를 연구하였다. ATAP의 첨가로 추진제의 연소 속도가 낮아지는 것은 ATAP가 산화제인 과연소만 암모늄의 분해를 억제한다기 보다는 열분해시 발열량을 적게 하기 때문이다. 따라서 알칼기가 큰 ATAP를 첨가한 추진제의 열분해시 발열량이 분자량이 작은 ATAP경우보다 더 적어서, 분자량이 큰 ATAP가 추진제의 연소 속도를 감소기키는 데 더 효과적이었다.
The effect of n-alkyl trimethyl ammonium perchlorate(ATAP)on the burning rate of HTPB/IPDI/AP solid propellants was investigated by thermal analysis and burning rate measurement. The reason that the addition of ATAP resulted in decreasing the burning rate of composite solid propellant appeared to be the reduction of the exother-mic energy during thermal decomposition rather than the suppression of the decomposition of AP. Since the exother-mic energy of ATAP with the large alkyl group was less than that of on with the small alkyl group, the former was more effective on the decrease in the burning rate of composite solid propellent than the latter.
