Abstract: A turbopump includes a casing, a rotational shaft rotatably supported on the casing, and an impeller mounted on a side of the rotational shaft and pressurizing a fluid flowing into the impeller from an inlet of the casing, wherein axial thrust is controlled as a clearance formed between the impeller and the casing in a length direction of the rotational shaft varies according to a fluid pressure difference between front and rear sides of the impeller.
