“…Pulsed and continuous-wave (CW) lasers have been widely used in PSP experiments (Morris et al 1992, Andreev et al 1993, Lifshitz et al 1993, Engler & Klein 1997, Lyonnet et al 1998. The narrow-band emission from a laser can be easily distinguished from emitted luminescence.…”

Key Words pressure-sensitive paints, optical measurement techniques, photogrammetry, aerodynamic loads, wind tunnel testing s Abstract An optical technique is described that is often used nowadays to measure surface pressures on wind tunnel models and flight vehicles. The technique uses luminescent coatings, which are painted on the model surface, excited by light of appropriate wavelength, and imaged with digital cameras. The intensity of the emitted light is inversely proportional to the surface pressure. Hence, the surface pressures can be measured efficiently and affordably with a high spatial resolution. The theory and chemistry of how such coatings work and the parameters that affect them are presented. The required hardware and software are described, with emphasis on the different measurement systems and procedures. The various error sources are discussed, and correction schemes that can be used to minimize them are presented. Sample results, covering a wide range of conditions and applications, are presented and discussed.

“…The response time t is therefore mainly controlled by the thickness I of the binder layer and can be written as (3) where D is the diffusion coefficient of oxygen, A more detailed description of different pressure sensitive paint formulations ("open PSP formulations", "binary paint") as well as a more complex theoretical background of the use of Stern-Volmer equation are presented in [7] and [8],…”

“…The PSP method gives qualitative as well as quantitative pressure images of the observed model surfaces [2], without any disturbance of conventional pressure tap measurements, that can influence the flow over the entire surface of a wind tunnel model and introduce measurement errors. Therefore, this method could be used on model surfaces for flow visualization [3] and it can also be used to provide detailed aerodynamic information about the model aerodynamics [4].…”

Visualization of aerodynamic effects on a three-dimensional double-delta wing aircraft model was conducted using an optical pressure measurement system, based on the Pressure Sensitive Paint (PSP) technique, and in addition a laser-light sheet method. The combination of PSP technology with the laser-light sheet method, provides a good understanding of the flow around the wind tunnel model. In recent years, this novel PSP-technology has attracted considerable attention in the aerospace community. The PSP technique can be used to realize absolute pressure measurements on a surface of a model and in addition to evaluate quantitative aerodynamic flow phenomena using a scientific grade camera and image processing techniques. The PSP system was tested in the Transonic Wind Tunnel of the German Aerospace Center in Gottingen (TWG) under real flow conditions. Instantaneous pressure distributions are recorded in almost real-time so that the recognition and analysis of the vortex dynamics on the model surface is possible. Even the vortex breakdown process, as well as the fine structured Kelvin-Helmholtz instabilities and secondary vortex structures, can be detected by this measurement technique.

“…This method can also be used for flow visualization and to provide detailed static pressure information about the model's aerodynamics. PSP techniques have been widely used in wind tunnels for investigations in transonic and supersonic flow [9]. The objectives of the aerodynamic testing of the plug nozzle model are to acquire new knowledge about:…”

SummaryPressure field measurements on a Linear Plug Nozzle model were conducted to evaluate the feasibility and accuracy of measurements using DLR's Pressure Sensitive Paint (PSP) system in the high-speed wind tunnel at Merkers (HWK) of TU-Dresden. A part of the nozzle surface was coated with binary PSP paint. Results show that the optical pressure measurement system with binary paint can be used in the HWK facility. In addition, the paper gives a summary of the thrust vector calculations based on measured static pressure distributions on the plug surface using thrust vector control.
