PURPOSE: A turbo pump system having a planetary gear device is provided to increase the efficiency of the turbo pump system by installing the planetary gear device between an oxidant pump and a fuel pump. CONSTITUTION: A turbo pump system comprises an oxidant pump(100), a fuel pump(200), a turbine(300) and a planetary gear device(400). The oxidant pump increases the pressure of oxidant to supply the oxidant to a combustion chamber. The oxidant pump comprises an oxidant pump shaft(110). The fuel pump increases pressure of fuel to supply the fuel to the combustion chamber. The fuel pump comprises a fuel pump shaft(210). The turbine transfers driving force to the fuel pump and the oxidant pump. The planetary gear device is coupled between the oxidant pump and the fuel pump. |
