20 Plus Years of Chimera Grid Development for the Space Shuttle. STS-107, Return to Flight, End of the Program

[摘要] This slide presentation reviews the progress in grid development for the space shuttle, with particular focus on the development from the los ofSTS-107 and the return to flight, to the end of the program. Included are views from the current Space Shuttle Launch Vehicle (SSLV) grid system, containing 1.8 million surface points, and 95+ million volume points.Charts showing wind tunnel tests comparisons, and Computational fluid dynamics (CFD) vs 1A613B wing pressures, wind tunnel test comparison with CFD of the proposed ice/frost ramp configuration are shown.The use of pressure sensitive paint and particle imaging velocimetry was used to support debris transport tools, The actual creation of the gridsand the use of overset CFD to assess the external tank redesign was also reviewed.It also asks was the use of the overset tool the right choice. The presentation ends with a review of the work to be done still.
