홀 추력기란? | 홀 추력기(Hall thruster)는 고리 또는 원통 형태의 공동을 갖는 정전기적 추력기(electrostatic thruster) 이다. 추력기 내 반지름 방향의 강한 자기장과 축 방향 전기장은, 전자를 E×B 표류(E-cross-B drift)를 통하여 추력기 내에 효율적으로 구속한다. | |
방전 전압과 추력, 방전 전류는 서로 어떤 관계인가? | 결과는 방전 전압이 증가할수록 전자 평균 에너지, 이온화율, 이온의 밀도가 증가하는 반면에 중성종의 밀도가 감소함을 나타내었다. 방전 전압과 추력, 방전 전류는 서로 비례하는 관계를 나타내었다. |
