Turbine assembly

A turbine assembly comprising:

• a first propellant that is any one of an oxidant and a fuel and is capable of catalytic decomposition;
• a second propellant that is the other of the oxidant and the fuel;
• a combustor configured to generate a propulsive force by receiving and combusting the first and second propellants;
• a first supply line configured to supply the first propellant to the combustor;
• a second supply line configured to supply the second propellant to the combustor;
• a first pump provided in the first supply line and configured to pressurize the first propellant;
• a second pump provided in the second supply line and configured to pressurize the second propellant;
• a turbine configured to be operated by a high-temperature gas and connected to the first and second pumps through a driving shaft;
• a third supply line having a front end connected to a high-temperature gas supply means, and a rear end connected to the turbine to supply the high-temperature gas to the turbine;
• a first exhaust turbine configured to be operated by an exhaust gas discharged after operating the turbine;
• a first booster pump connected to the first exhaust turbine through a first exhaust driving shaft, provided at a front end of the first supply line and configured to increase supply pressure of the first propellant by using an energy generated by the first exhaust turbine operated by the exhaust gas;
• and
• a fourth supply line having a front end connected to the turbine, and a rear end connected to the first exhaust turbine to supply the exhaust gas to the first exhaust turbine.
