Abstract

As the interest in lunar exploration increases, a throttleable engine is regarded as a important technology. Variable area injectors have been identified to be the most reliable throttling method. Pintle injector is a representative injector of the variable method. It has a simple design and inherent combustion stability. Therefore, it is necessary to research the pintle injector. The present study investigates the concept of the injector, the design factors, and the latest development trends for pintle injector design.

현재 국내외적으로 달 탐사에 대한 관심이 높아지고 있다. 달 탐사를 위해서는 가변추력 엔진 기술의 확보가 매우 중요하다고 할 수 있다. 엔진 추력 조절 방식 중 면적 조절을 통한 유량 변경 방식은 가장 신뢰성 있는 기술로 평가되며, 대표적으로 핀틀 분사기가 있다. 핀틀 분사기는 구조가 비교적 단순하며 연소불안정에 강하다는 강점을 가진다. 따라서 현 시점에서 가변추력을 위해 신뢰성 있는 기술로 여겨지는 핀틀 분사기에 대한 연구가 선행될 필요가 있다. 본 연구에서는 핀틀 분사기의 기본 개념과 설계 인자를 살펴보고 전반적인 설계 절차를 확립하며, 국내외 최신 개발 동향을 파악하고자 하였다.
