Directional dynamic absolute pressure sensor shroud and arrangement

A pressure sensor assembly for simultaneously providing a time-resolved total pressure and steady state flow angles of an airflow, said assembly comprising:

• an outer shroud including a front face, a rear face, and a central bore having a wall, wherein the central bore includes a cylindrical portion and a front tapered portion extending through the front face of the shroud, and wherein the central bore is offset from a center axis of the shroud;
• a dynamic absolute pressure sensor positioned within the bore and providing a time-resolved total pressure measurement, wherein the absolute pressure sensor is positioned within the bore so as to be spaced from the wall and allow the airflow to flow through the bore between the sensor and the wall;
• and
• first and second spaced apart static pressure ports extending from the front face of the shroud to the rear face of the shroud and adjacent to the bore, said first and second pressure ports providing a pressure that can be measured by pressure probes, wherein a combination of the time-resolved total pressure measurement and pressure measurements from the probes provides a steady state flow angle of the airflow.

A pressure sensor assembly for simultaneously providing a time-resolved total pressure and steady state flow angles for testing airflow for an aircraft engine inlet, said assembly comprising:

• an outer shroud including a front face, a rear face, and a central bore having a wall, wherein the central bore is offset from a center axis of the shroud;
• a dynamic absolute pressure sensor positioned within the bore and providing a time-resolved total airflow pressure measurement;
• and
• first and second spaced apart static pressure ports extending from the front face of the shroud to the rear face of the shroud and adjacent to the bore, said first and second pressure ports providing a pressure that can be measured by pressure probes, wherein a combination of the time-resolved total pressure measurement and pressure measurements from the probes provides a steady state flow angle of the airflow in a yaw and pitch direction.
