스페이스x 근황.jpg
인류역사상 가장 크고 강한 스타쉽 로켓 2차 테스트발사 준비중
거기에 핫스테이징 기술 테스트 준비중
핫 스테이징이란 1단 부스터와 2단 우주선이 분리될때
보통은 단분리후 2단 연소가 시작되는데
단분리 전부터 2단 연소를 먼저 시작하고 그 뒤에 단분리를 하는 시스템임
그것때문에 스테이지 사이에 저렇게 구멍이 송송 뚫린 디자인이 됨.
완전 신기술은 아니고 예전부터 있던 방식임.
이런식으로 아직 분리가 안된상황에서 2단연소를 하면서 단분리를함.
이렇게 했을때 장점은 단분리가 되고 2단연소전까지 추력 공백이 생기고 속도 손실이 발생하는데
이걸 최소화 하기위해 핫스테이징 방법을 쓰려는것.
