TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Significant advances in the use of fast responding Pressure-Sensitive Paint have recently been achieved as demonstrated by a multi-camera fast PSP test conducted in the 16 foot transonic wind tunnel at AEDC. The unsteady pressure results from this test demonstrated excellent accuracy and spatial resolution, establishing the technical readiness of the fast PSP sensor. During the program, two issues were identified that would significantly improve the fast PSP system performance, 1) real-time data processing, and 2) acquisition of both mean and unsteady data using a single entry. Here we propose the continued development of the fast PSP system by addressing these issues. To enable real-time data processing, a system composed of a computer with a large block of memory, a multi-core processer, and several high end video cards (GPUs) has been assembled. Modern GPUs include thousands of floating point processors and large blocks of memory which enable parallel computations to be executed on individual images. Fast PSP data is an ideal application of this technology as many of the computations can be performed on each image independently. Preliminary tests by ISSI have demonstrated improvements of a factor of three to thirty in processing time using this approach. Acquisition of both mean and unsteady pressure during a single tunnel entry would increase tunnel productivity and can be used to improve the accuracy of the unsteady pressure data. Unfortunately, fast PSPs are generally very temperature sensitive which limits their use in acquiring mean pressure data. ISSI has recently developed a fast PSP formulation with low temperature sensitivity. This formulation will be optimized for use in large wind tunnels and enable acquisition of mean and unsteady pressure data using a single PSP.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
There is considerable interest in measurements of unsteady pressure for evaluation of computational models and study of flow physics on hypersonic inlets, compressors, aeroelasticity, and rotorcraft aerodynamics. This system will provide advancement of the state-of-the-art in this field as the proposed research will develop a system for the measurement of continuous distributions unsteady pressure that require no physical modifications to the model and produces data with high spatial resolution. The fast PSP technology could be deployed to wind tunnels at Ames, Glenn, and Langley for testing on a variety of programs that have need of unsteady pressure measurements. Specific applications include Aircraft Acoustics, Flow Control, Supersonic Inlets, and Launch Vehicles.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
There is considerable interest in measurements of unsteady pressure for evaluation of computational models and study of flow physics on hypersonic inlets, compressors, acoustics, and aeroelasticity. This system will provide advancement of the state-of-the-art in this field as the proposed research will develop a system for the measurement of continuous distributions unsteady pressure that requires no physical modifications to the model and produces data with high spatial resolution. ISSI has sold several production PSP systems world-wide. There is significant interest among these customers in fast responding PSP. ISSI is currently involved in discussions with several commercial aircraft manufactures regarding the potential of a fast responding PSP system for evaluation of landing bay acoustics. Development of this system for wind tunnel testing is seen as a first step in this process.
