Industrial Automatic Control Systems and Controllers Annotation << Back To the Question of Improving the Accuracy of Measuring Altitude-speed Parameters in Automated Control Systems of Aircraft Luu Cong Kiem, I.P. Efimov The article deal with a mathematical model for finding the geometric parameters of air pressure probes for a given value of the deviation of the pressure coefficient, obtained as a result of simulation in ANSYS of a variational series of fl ow-type air pressure probes. Software has been developed to search for geometric parameters of air pressure probes which deviation of pressure coefficient does not exceed a set value. An example of searching for geometric parameters of air pressure probes with a maximum deviation tolerance of the pressure coefficient of 0,16 is given. Keywords: ANSYS, static pressure; flow-type air pressure probe; pressure perception; aerodynamic error; geometric parameters; altitude-speed parameters; flight speed; pressure coefficient; deviation of pressure coefficient.
