摘要：

The control loop of scramjet combustor was designed to control the thrust force increment and combustor-isolator interaction (CII) by feedback of force and isolator pressure measurements, where the fuel mass flow was regulated by fuel mass flow control system based on controllable cavitating Venturi. On the direct-connect test system, two experiments were conducted to implement single level thrust force control and multi-level thrust force/CII control, respectively. The test results show that; the fuel mass flow control system works reliably with fuel regulated accurately by directed movement of Venturi; the thrust force varies with fuel mass flow almost synchronously; and the thrust force increment and CII are controlled efficiently. This work lays a foundation for further study of scramjet combustor control.
