specific Embodiment approach
[0035] The specific embodiment of the present invention comprises the following steps:
[0036] The first step is to collect the angle of attack α and angle of sideslip β of the flow field of the controlled object, and substitute the angle of attack α and angle of sideslip β into the DOE-based surrogate model obtained through the theory of experimental design through array calculation, and obtain the required The nozzle arrangement matrix of the job [K];
[0037] The second step is to collect the incoming flow velocity V of the flow field of the controlled object ∞ and fluid density ρ ∞ , calculated by zero mass jet excitation frequency, the future flow velocity V ∞ and fluid density ρ ∞ Substituting the DOE-based surrogate model obtained through the experimental design theory, so as to obtain a reference excitation frequency f 0 ;
[0038] In the third step, the nozzle arrangement matrix [K] obtained in the first and second steps, the angle of attack α, the sideslip angl...
