The present invention relates to an oxidizer piping fixing device in a fuel tank, which includes: a fuel tank (10) in which fuel is received and an inner partition (11) is formed; an oxidizer tank (20) which is provided on an upper side of the fuel tank (10) and in which an oxidizer is received; an oxidizer pipe (21) connected into the oxidizer tank (20) and penetrating a space between the inner partitions (11) of the fuel tank (10) to be connected to an engine; and a fixing device provided between the inner partition (11) and the oxidizer pipe (21), thereby removing heat air force caused by being exposed to the outside, reducing the entire weight, and more easily implementing control of a natural frequency.

    본 발명은 내부에 연료가 수용되되 내측에 내부격벽(11)이 형성되는 연료탱크(10), 상기 연료탱크(10)의 상측에 배치되되 내부에 산화제가 수용되는 산화제탱크(20), 상기 산화제탱크(20) 내부와 연결되되 상기 연료탱크(10)의 내부격벽(11) 사이를 관통하여 엔진으로 연결되는 산화제배관(21) 및 상기 내부격벽(11) 및 산화제배관(21) 사이에 배치되는 고정장치를 포함하여 이루어져, 외부 노출에 따른 열공력을 제거하고 전체 중량을 감소시킴과 고유진동수 제어가 보다 용이하게 이루지는 연료탱크 내 산화제배관 고정장치에 관한 것이다.
