초록

본 논문은 한국형 2.75 인치 로켓 추진기관의 독자 모델 개발에 관하여 기술하였다. 개발된 한국형 2.75 인치 로켓 추진기관은 추진제 그레인의 형상변경을 통하여 화염안정성을 증대시켰으며, 점화장치에 EMI 필터를 장착하여 우발점화 방지기능을 추가하였다. 그리고 노즐 형상 변경 및 날개 수 증가를 통하여 비행안정성의 향상을 가질 수 있었다. 지상연소시험 및 온도충격시험을 통해 추진제의 성능을 검증하였으며, 약 210 발의 비행시험을 통해 기 배치된 추진기관과 비행성능이 동일함을 입증하였다. 성능개량과 더불어 한국형 독자모델 개발로 인한 지적재산권 문제 극복에 기여할 수 있는 근간을 마련했다는데 그 의의가 있다.

In this paper, the development of unique model of the 2.75 inch rocket propulsion system is described. Recently developed korean 2.75 inch rocket propulsion system shows the improvement of a flame stability resulted from a change in the configuration of propellant grain, and of an incidental ignition protection function using the EMI(electromagnetic interference) filter on ignition system. Moreover it is shown that a directional flight stability is improved by increasing the number of fins and changing the nozzle configuration. Static firing test and thermal shock test were conducted for the validation before flight, and flight test of 210 rounds of rockets was conducted to verify the trajectory uniformity. In addition, intellectual property issues can be overcome with the unique korean 2.75 inch rocket motor as well as the performance improvement.
