A System for Time Resolved Surface Pressure Measurements using Fast Pressure Sensitive Paint (University of Arizona)
Abstract
Funding is requested for instrumentation that allows capturing time resolved surface pressure data by using fast pressure sensitive paint (PSP). Such system will enable the analysis of unsteady flow phenomena, for example pitching airfoils or dynamically actuated flaps. Additionally, a fast PSP system capable of acquiring data at very short exposure times can also be used for the analysisof pressure fields on rotor blades. Pressure contours covering instantaneously a wing, a rotor or an entire model provide invaluable information that may lead to an optimized design of the model in the presence and absence of active flow control (AFC). This is hard to achieve with pressure tapsor pressure transducers that provide information at a point. Several ongoing and planned projectsin the AeroLab at the University of Arizona would greatly benefit from the requested instrumentation, all of which are of high interest to DoD.
