Abstract An Organic Rankine Cycle (ORC) for thermal absorption and recovery system is proposed for cooling scramjet. The heat which must be taken away by fuel coolant from cooling scramjet is converted to other forms of energy. The performance parameter of an ORC thermal management system has been performed and the thermodynamic analysis method of the system is depicted. The efficiency, the output power of the system and the multiplication ratio of fuel heat sink with different working fluids by evaporation pressure and condensation temperature are evaluated. Numerical results indicate that the performance parameters have different changing with evaporation pressure and condensation temperature. Therefore, it can be concluded from thermodynamic analysis that valuable output power can be drawn by employing an ORC thermal absorption and recovery system for hypersonic vehicle
