摘要: Abstract Sustained power supply and thermal protection of electronic elements are two essential problems for developing long-endurance reusable hypersonic aircrafts. In this study, a combined cooling (CPC) system is established between high temperature incoming air low fuel based on turbine organic Rankine cycle (ORC). The investigated thermodynamic analysis. rotating modeled with mean diameter 150 mm 3D CFD simulation. turbulence models main flow channel k-omega SST, respectively. And the method verified land experimental test. Finally, performance CPC theoretically researched. ORC can obviously increase output system. With designed turbine, real 118.5 kW, higher by 20.7% than turbine’s 98.2 kW. obtained mass rate 0.292 kg/s. blade be cooled reasonable 5 g/s per blade.
