Query: Standard reference for high-speed tunnel design

This book is an excellent standard reference for the design oftransonic, supersonic, and hypersonic wind tunnels. Was often used in the design of the Mach-4 and Mach-6 Ludwieg tubes at Purdue University, 1990-2001. Although it is dated, it is the only comprehensive monograph. See also "Experimental Methods of Hypersonics" by Lukasiewicz, which contains less design info.A great deal of facility construction went on before the publication date of 1965, and not all that many facilities have been built since.
