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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
