In accordance with the present invention, a cryogenic liquid fuel tank includes: a first module member (11) comprising a first planar part (111) and a first curved part (112) having a diameter increasing from the periphery of the first planar part (111) toward the front; and a second module member (12) comprising a second planar part (121) having the same size as the first planar part (111) and having a circular planar shape and a second curved part (122) having a diameter increasing from the periphery of the second planar part (121) toward the rear, wherein the first module member (11) and the second module member (12) are alternately and repetitively connected, the first planar part (111) and the second planar part (121), which are adjacent to each other, are in surface contact, and the first curved part (112) and the second curved part (122) have the peripheries of ends thereof connected. Therefore, the present invention is capable of enhancing the assembly and production efficiency of a fuel tank.

    본 발명에 따른 극저온 액체 연료 탱크는 원형의 평면 형상을 갖는 제1 평면부(111)와 제1 평면부(111)의 둘레로부터 전방 쪽으로 직경이 증가하는 형상의 제1 곡면부(112)로 이루어지는 제1 모듈 부재(11); 및 상기 제1 평면부(111)와 같은 크기를 가지며 원형의 평면 형상을 갖는 제2 평면부(121)와 상기 제2 평면부(121)의 둘레로부터 후방 쪽으로 직경이 증가하는 형상의 제2 곡면부(122)로 이루어지는 제2 모듈 부재(12)를 포함하고, 상기 제1 모듈 부재(11)와 상기 제2 모듈 부재(12)는 교대로 반복하여 연결되며, 서로 인접하고 있는 상기 제1 평면부(111)와 상기 제2 평면부(121)는 면접하고 있고, 서로 인접하고 있는 상기 제1 곡면부(112)와 상기 제2 곡면부(122)는 그 말단의 둘레가 연결되는 것을 특징으로 한다.
