Annotations languages:

The results of delay coefficient computations of static pressure and amendments on the delay of pressure to the flight height and speed of aircraft Su-27 through the method of determination of gas-dynamic parameters are resulted. The results of pressure computation in the system with different geometrical parameters are shown, the rational are chosen. The measuring system of air parameters with new pipelines diameters has the improved inertia descriptions. The got results can be used for modernization of aircraft in rising of flight parameters measuring exactness.
Keywords: measuring system, error of pressure delay, delay coefficient
