An aircraft inlet closed loop flow control apparatus and a control method

The present invention provides a closed loop aircraft inlet flow control device and a control method, control device microjet regulator, signal processor, a real-time controller, pressure sensor and a pressure pulsations sensors, real-time adjustment by microfluidization pressure , closed-loop control of the flow of intake flow. The control method comprising the steps of: a pressure sensor failure is determined; B Analyzing pulsating pressure sensor fault; c... Calculating dimensionless feedback value;. D calculate a control target value;. E determines the steady state and updating control instructions;. F signal measurement and processing; g. Repeat steps a ~ f. Aircraft air intake of the present invention a closed loop flow control device and a control method can reduce the number of sensors, to improve the reliability and maintainability of the control system to reduce the sensitivity of the flight control system, it is advantageous in simplifying the control law design and improve Control effect.
