Abstract
A system for total pressure measurement of a propulsive stream through a turbine engine, the system incorporates a track circumferentially mounted on a fan exhaust nozzle proximate a trailing edge. A carriage is mounted in the track and adapted for translation through a range of azimuthal angles relative to an engine centerline. A pressure measurement rake extends from the carriage and has a probe mount protruding radially inward into a fan flow duct with a plurality of pressure probes mounted to a leading edge of the probe mount.

19. A method for total pressure measurement of a propulsive stream, the method comprising:
-
activating a motor through a motor controller as commanded by a control system; positioning a carriage of a pressure measurement rake at a desired location in a track; transmitting pressure data from radially spaced locations of a plurality of pressure probes mounted to the carriage through a telemetry unit to a data processor; and activating the motor to reposition the carriage at a next selected location. - View Dependent Claims (20)
