Over to these parameter, the stagnation states can also be determined using this analyzer. The five probe flow analyzer is used to determine the wind tunnel test section parameters like flow angularity, Pitot pressures, static pressures, wave angles, and the presence of test section noise. Hence in order to overcome this difficulties in measurement, a five probe flow analyzer has been designed. When the wedge or cone angles are maximum, more accurate results are also obtained, but it's not possible to have a maximum angle cone or wedge because of the detached wave and tunnel blockage factors. In the analysis it is noted that the sensitivities of the calibrating instruments are maximum when it is either cone or wedge shaped. The calibration of a wind tunnel includes determining the Mach number range ad pressure range throughout the test section of the flow throughout the pattern of operating velocity. Usually a subsonic wind tunnel is calibrated using a normal Pitot tube and supersonic wind tunnels with high efficiency probes. The models are being tested at a mixture of flow velocity. The flow angularity in a wind tunnel plays a major role in test section when testing models.
