초록

로켓의 노즐 외부에서 형성되는 플룸으로 인하여 발사 위치나 비행궤적이 노출 될 수 있는데, 본 논문에서는 플룸을 감소시킬 수 있는 고체 추진제의 후연소 반응 억제제에 대하여 연구 결과를 제시하였다. 후연소 방지제가 무연계 고체추진제의 내탄도 성능과 일차 연기에 미치는 영향을 분석하였으며, 후연소 반응 방지제로 $K_2SO_4$를 1.1% 적용하여 후연소 반응이 크게 감소하는 것을 알 수 있었다. 또한 $K_2SO_4$의 함량이 증가하면 압력지수가 미세하게 증가하며, 1차 연기의 발생량도 증가하므로 1.1% 이하를 사용해야 AGARD 기준으로 1차 연기 A등급에 부합되는 것으로 분석되었다.

This paper describes a study on after-burning suppressant in a solid propellant to reduce the plume formed outside of rocket nozzles, which could expose the launch site and the flight track. The minimum smoke propellant to enhance the stealth ability was formulated in terms of the kinds and the effects of after-burning suppressant on the ballistic performance and the amount of primary smoke. A after-burning suppressant, $K_2SO_4$ of about 1.1% weight content was found to show profound reduction of the rocket plume, giving negligibly slight increase in pressure exponent of burning rate. Also minimum smoke propellant with less than 1.1% of $K_2SO_4$ corresponds to A-class satisfaction in primary smoke by AGARD standard.
