We have previously reported that the PBE (Partial Bleed Expander) cycle LH2/LO2 engine has good performance at a 10kN-thrust. In this report, we discuss the PBE cycle LH2/LO2 engine and other low-temperature-cycle engines at a 100kN-thrust. The PBE cycle 100kN engine has the same engine performance as that of the GG (Gas generater) cycle engine. Among the engine whose thrust chambers are regeneratively cooled, the PBE cycle 100kN engine has the best performance; start transient simulation analysis showed that the PBE cycle engine can start without trouble. It is not suitable that both the nozzle skirt and the thrust chamber of the PBE cycle 100kN engine be regeneratively cooled.
