Abstract: This paper outlines the design and development of the 450 N Ethanol/H 2 O 2 liquid rocket engine, "Polaris-1."It provides a preliminary approach to liquid rocket design.The combustion chamber was designed using CEA analysis and method to minimize wall surface area.A bell nozzle with a third-order polynomial contour was designed.To improve performance, a bi-swirling injector and film cooling technique were applied.The torch ignition method was adopted, and a 3-DoF flight simulation predicted a maximum altitude of 225 meters.Future work will validate engine performance through 6-DoF simulations and combustion tests, with redesigns made if necessary based on the results.초 록 본 논문은 450 N급 Ethanol/H 2 O 2 액체 로켓 엔진 "Polaris-1"의 설계 및 개발 과정을 다루며, 액체 로켓 설계에 필요한 기초적인 접근 방법을 제시하고자 한다.연소실 형상은 CEA 분석과 벽면적 최소화 기법을 통해 설계하였으며, 노즐은 3차 다항식 형상의 벨 노즐로 선정하였다.또한,
