| Abstract |
In response to the growing demand for unsteady aerodynamic measurements, there has been an increased interest in utilizing pressure scanning modules. The Wiener-filtered inverse system response model has demonstrated effectiveness in reconstructing intricate unsteady pressure signals obtained remotely through pressure scanners. The evolution of small, compact direct-mount pressure scanners presents an opportunity to reduce pneumatic tubing length, connecting measurement ports to the scanner manifold. This reduction enhances the dynamic range for unsteady pressure measurements when coupled with signal reconstruction. However, it is essential to note that the reduction in tubing length, while reducing time lag in remote measurements, also introduces a heightened risk of signal amplification due to resonance effects in the tubing. This amplification poses a challenge as it can distort the signal, underscoring the need for signal reconstruction. This study assesses the effectiveness of a direct-mount pressure scanner in capturing time-resolved pressure data around a symmetric flat plate in static angle of attack configurations. Employing various analytical tools, the accuracy of reconstructed unsteady pressure signals from remote measurements using the direct-mount pressure scanner will be thoroughly evaluated. |
