Abstract
A dynamic five-hole probe includes a pressure sensing part, a pressure measuring hole transition section, a pressure acquisition section, dynamic pressure sensors and flexible wall pressure buffering tubes, the pressure sensing part being provided with pressure measuring holes to sense three dimensional dynamic pressure components of an airflow; the pressure measuring hole transition section transits from an inlet end surface five-hole structure into an outlet end surface five-hole structure; the pressure acquisition section has therein a centrally symmetric pressure measuring hole structure; pressure sensor mounting holes are in communication with the five pressure measuring holes; each of the dynamic pressure sensors is mounted in a corresponding one of the sensor mounting holes to measure a dynamic pressure of the airflow. The pressure sensing part may have a diameter of 3 mm or less.
