Aerodynamic Errors of the Systems Aimed at Measuring the Static Pressure of an Aircraft in the Sliding Modes of Flight

详细

We propose mathematical models of errors of the onboard measurements of static pressure of an aircraft in the sliding modes of flight based on the use of hydrodynamic models of flow around thin bodies. We also analyze and estimate the schemes of location of Pitot static probes traditionally used in the aviation practice, as well as the algorithms intended for the compensation of errors in the calculators of air-data systems. The results of determination of the component of aerodynamic error in the sliding modes of flight are presented. The accumulated data have been obtained in the course of flight tests of numerous transport aircrafts.
