Industrial Automatic Control Systems and Controllers Annotation << Back Mathematical Model for Calculating the Deviation of Pressure Coefficient of Flow-type Static Pressure Probe Caused by Airflow Angularity Luu Cong Kiem, I.P. Efimov The article deals with a mathematical model of flow-type static pressure probe, which connects the deviation of pressure coefficient with the geometric parameters of flow-type static pressure probe and the angle of airflow angularity. The model is developed on the basis of the results of modeling in ANSYS of a variational series of flow-type static pressure probes. Combinations of the geometric parameters of flow-type static pressure probe were obtained, at which the deviation of pressure coefficient of flow-type static pressure probe, caused by airflow angularity, was minimal. Keywords: flow-type static pressure probe; static pressure; pressure perception; aerodynamic error; geometric parameters; altitude-speed parameters; airflow angularity; pressure coefficient; deviation of pressure coeffi cient; ANSYS.
