AI Technical Summary
Existing scramjet engines cannot effectively adjust the distribution of combustion heat release zones under a wide range of inflow conditions, resulting in unstable operating conditions and an inability to suppress combustion oscillations in a timely manner.
By adopting a distributed fuel injection scheme and combining a combustion mode discrimination feedback mechanism based on real-time wall pressure measurement, the distribution of combustion heat release zone and the suppression of combustion oscillations in the combustion chamber are achieved by adjusting the fuel injection strategy.
It achieves smooth transition of combustion modes and effective suppression of combustion oscillations under a wide range of inflow conditions, thereby improving the operational robustness of the scramjet engine.
