  perforation
It is shown that perforation as a hydraulic factor can improve significantly the parameters of the sonic ejector in the critical regime.
      
Induction of subsonic wind tunnels with slight perforation
      
The plane limiting boundary problem on the subsonic flow over a dipole is solved in elementary functions for the case of small velocity perturbations at the stream boundary and a low perforation factor.
      
The solution obtained, while not coinciding with the solution for the case of unperforated walls everywhere when the perforation factor equals zero, gives a simple rule for allowing for induction.
      
From the solution obtained, the optimum degree of perforation of the wall is found for which distortion of the pressure coefficient on the surface of the model is a minimum in comparison with the unbounded flow round the body.
