Abstract
Development of a reliable instrumentation for the measurement of the airflow characteristics has great importance during a flight test campaign or during wind tunnel tests. The airspeed, static pressure, airflow angles, and other variables must be well known since they are deeply related to the aerodynamic characteristics of an airplane. Among the several types of instruments for this duty, we chose the multi-hole probe as a device for the measurements due to its wide applicability. The aim of this paper is to show the design and development of a five-hole probe that was used to update the flight test platform CEA-FDAS, so that it can generate more reliable data and that can be used for broader operating conditions. The probe was designed based on previous works developed in this laboratory and it was calibrated in a subsonic wind-tunnel to check its accuracy and precision, ensuring its reliability. The developed probe is capable to operate in several flight conditions of a light aircraft and can be used during a certification flight test campaign. Moreover, its operating range can be extended by modifying its pressure sensors or its tip shape. It was designed in such a way that it can be adapted to be used for different scenarios.
