Description

technical field

[0001] The present application relates to the technical field of aero-engines, and specifically provides a device for measuring aerodynamic parameters of an engine flow field. Background technique

[0002] When measuring the total temperature, total pressure and static pressure parameters of the airflow in the engine flow field, the measuring sensor in the measuring device has direction sensitivity. Parameter measurement requires that the pressure-sensing hole of the measuring sensor head is parallel to the direction of the incoming flow, and the direction-insensitive angle range of various measuring sensors is limited.

[0003] At present, the commonly used fixed probes for total temperature, total pressure and static pressure measurement probes cannot adjust the angles of the measuring heads on the probes facing the incoming flow after installation, and when measuring the flow field parameters of certain sections in the engine test , the direction of the i...
