TLDR
In this paper, a method for calibrating a five-hole probe for extending the useful measurement range up to flow angularities of 85° is described, which involves adjustment of the calibration coefficients to allow valid calibration at larger flow angles.Abstract:
A new method is described for calibrating a five-hole probe for extending the useful measurement range up to flow angularities of 85°. The calibration method involves adjustment of the calibration coefficients to allow valid calibration at larger flow angles. The extended range calibration curves for flow angularity, total and static pressures are presented. The present range is valid in pitch only when the yaw ports are nulled.read more

Development of a functional relationship between port pressures and flow properties for the calibration and application of multihole probes to highly three-dimensional flows
A. J. Pisasale,Noor A. Ahmed +1 more
TL;DR: In this paper, a functional relationship is developed, based on theoretical considerations, that relates the port pressure directly to the flow properties and details a procedure that enables flow properties to be determined from the measured pressures of the multihole probe.

Theory and calibration of non-nulling seven-hole cone probes for use in complex flow measurement
TL;DR: A seven-hole conical pressure probe capable of measuring flow conditions at angles up to 75 degrees relative to its axis is described in this article, where three-variable third order polynomials are used to represent local values of total pressure, static pressure, Mach number and relative flow angles.

Measurement of post-separated flowfields on airfoils
TL;DR: In this paper, a small pitch yaw pressure probe was used for remote traversing in the vertical axis and remote yawing of plus or minus 180 deg. The calibration of the probe indicates a useful pitch angle range of about + or minus 45 deg.
