FIELD: physics.
SUBSTANCE: invention relates to experimental aerodynamics, particularly to wind tunnels. Disclosed is method and device for its implementation, during determination of difference between preset and measured pressure can calculate fictitious or actual cross-section area of leakage/leakage slot Fni and determine control element - throttling or filling.
EFFECT: technical result consists in the possibility to obtain this information under conditions of incomplete information on the reason of pressure change in the wind tunnel circuit, and also to take into account the perturbing factor at pressure control, and application in automatic control system of various types of wind tunnels with high accuracy in automatic mode.
