Turbine assembly

A turbine assembly comprising:

• a first propellant that is any one of an oxidant and fuel and is capable of catalytic decomposition;
• a second propellant that is the other of the oxidant and 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 a high-temperature gas to the turbine;
• a first exhaust turbine configured to be operated by an exhaust gas discharged after operating the turbine;
• an energy storage part connected to the first exhaust turbine through a first exhaust driving shaft and configured to store at least a part of 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.
