Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Mathematical Model of a Static Pressure Probe With an External Profiled Surface LUU CONG KIEM, MAI XUAN DUC, I.P. EFIMOV The article presents a mathematical model and the results of modeling a static pressure probe with an external profi led surface at an airfl ow rate from 13.89 m/s to 69.44 m/s. The model was obtained on the basis of modeling the static pressure probes with an external profi led surface in the ANSYS program. Comparison of the results of aerodynamic tests of static pressure probe with an external profi led surface in the wind tunnel of Ulyanovsk Instrument Manufacturing Design Bureau, JSC, and their modeling in the ANSYS program is presented. The developed mathematical model makes it possible to calculate the pressure coeffi cient of static pressure probe according to the following initial data: geometric parameters of static pressure probe, the speed of the incoming airfl ow and the fl ight altitude. The results of the search for combinations of geometric parameters of static pressure probe with an external profi led surface, the deviation of the pressure coeffi cient of which is minimal when the speed of the incoming airfl ow changes, are presented. Keywords: static pressure probe with an external profi led surface, static pressure, pressure perception, pressure coefficient, ANSYS. DOI: 10.25791/pribor.1.2025.1553 Pp. 40-49.
