Research on Optimal Regulating Rule for Scramjet Control

摘要: Fuel control is one of the key technologies to scramjet engines, and it must effectively deal with varying inlet conditions combustion modes. For a successful system, regulating rules, that is, fuel injection rules for each injector, are great importance, which determines objects engines in whole flight envelop. This paper provides method obtaining optimal control. The based on conception firstly fixes total flow rate, then optimizes distribution rate obtain performance thrust forces stabilities.
