Evaluation of a Wedge on a Force Balance as a Flow Angle Probe

Abstract

A wedge wing on a force balance, designed for use at Mach numbers 1.6 and 2.0, has been evaluated as a continuously moving flow angle probe and calibrated in the range of Mach numbers from 0.6 to 1.3. Moving at standard speeds of the Captive Trajectory System (CTS), it has proved to be accurate and repeatable when operating in the three translational modes and the roll mode. Performance is also reported in the pitch and yaw motions. An extensive survey made at Mach number 0.6 shows the flow direction in the 4 tunnel used to be upward and toward the north wall with maximum components of 0.58 deg in pitch and 0.52 deg in yaw.
